-> **Important Note** Katenary is a tool to help building Helm Chart from a docker-compose file, but docker-compose doesn't propose as many features as what can do Kubernetes. So, we strongly recommend to use Katenary as a "bootstrap" tool and then to manually enhance the generated helm chart.

+<h3>🚀 Unleash Productivity with Katenary! 🚀</h3>
+</div>
+
+Tired of manual conversions? Katenary harnesses the labels from your "`compose`" file to craft complete Helm Charts
+effortlessly, saving you time and energy.
+
+🛠️ Simple automated CLI: Katenary handles the grunt work, generating everything needed for seamless service binding
+and Helm Chart creation.
+
+💡 Effortless Efficiency: You only need to add labels when it's necessary to precise things.
+Then call `katenary convert` and let the magic happen.
+
+## What ?
+
+Katenary is a tool to help to transform `compose` (`docker compose`, `podman compose`, `nerdctl compose`, ...) files
+to a working Helm Chart for Kubernetes.
+
+Today, it's partially developed in collaboration with [Klee Group](https://www.kleegroup.com). Note that Katenary is
+and **will stay an open source and free (as freedom) project**. We are convinced that the best way to make it better is to
+share it with the community.
+
+The main developer is [Patrice FERLET](https://repo.katenary.io/metal3d).
+
+## Install
+
+You can download the binaries from the [Release](https://repo.katenary.io/Katenary/katenary/releases) section. Copy the binary
+and rename it to `katenary`. Place the binary inside your `PATH`. You should now be able to call the `katenary` command.
+
+On Linux, you can use the `install.sh` from the repository to install it in your `$HOME/.local/bin` directory:
+
+```bash
+sh <(curl -sSL https://repo.katenary.io/Katenary/katenary/raw/branch/master/install.sh)
+```
+
+All OS, if you've installed Go on your computer, you can install using:
+
+```bash
+go install -u katenary.io/cmd@latest
+# or use a release
+go install -u katenary.io/cmd@v3.0.0
+```
+
+## Or, build yourself
 
 If you've got `podman` or `docker`, you can build `katenary` by using:
 
@@ -12,62 +63,106 @@ make build
 ```
 
 You can then install it with:
+
 ```bash
 make install
 ```
 
-It will use the default PREFIX (`~/.local/`) to install the binary in the `bin` subdirectory. You can force the PREFIX value at install time, but maybe you need to use "sudo":

-# Usage
+If that goes wrong, you can use your local Go compiler:
 
 ```bash
-Usage of katenary:
-  -appname string
-    	sive the helm chart app name (default "MyApp")
-  -appversion string
-    	set the chart appVersion (default "0.0.1")
-  -chart-dir string
-    	set the chart directory (default "chart")
-  -compose string
-    	set the compose file to parse (default "docker-compose.yaml")
-  -force
-    	force the removal of the chart-dir
-  -version
-    	Show version and exit
+make build GO=local
+
+# To force OS or architecture
+make build GO=local GOOS=linux GOARCH=arm64
 ```
 
-Katenary will try to find a `docker-compose.yaml` file inside the current directory. It will check *the existence of the `chart` directory to create a new Helm Chart inside a named subdirectory. Katenary will ask you if you want to delete it before recreating.
+Then place the `katenary` binary file inside your PATH.
+
+## Tips
+
+We strongly recommend adding the completion call to you SHELL using the common `bashrc`, or whatever the profile file
+you use.
+
+E.g.,
+
+```bash
+# bash in ~/.bashrc file
+source <(katenary completion bash)
+# if the documentation breaks a bit your completion:
+source <(katenary completion bash --no-description)
+
+# zsh in ~/.zshrc
+source <(katenary completion zsh)
+
+# fish in ~/.config/fish/config.fish
+katenary completion fish | source
+
+# experimental
+# powershell (as we don't provide any support on Windows yet, please avoid this...)
+```
+
+## Usage
+
+```text
+
+Katenary is a tool to convert compose files to Helm Charts.
+
+Each [command] and subcommand has got an "help" and "--help" flag to show more information.
+
+Usage:
+  katenary [command]
+
+Examples:
+  katenary convert -c docker-compose.yml -o ./charts
+
+Available Commands:
+  completion        Generates completion scripts
+  convert           Converts a docker-compose file to a Helm Chart
+  hash-composefiles Print the hash of the composefiles
+  help              Help about any command
+  help-labels       Print the labels help for all or a specific label
+  schema            Print the schema of the katenary file
+  version           Print the version number of Katenary
+
+Flags:
+  -h, --help      help for katenary
+  -v, --version   version for katenary
+
+Use "katenary [command] --help" for more information about a command.
+```
+
+Katenary will try to find a `docker-compose.yaml` or `docker-compose.yml` file inside the current directory. It will
+check \*the existence of the `chart` directory to create a new Helm Chart inside a named subdirectory. Katenary will ask
+you if you want to delete it before recreating.
 
 It creates a subdirectory inside `chart` that is named with the `appname` option (default is `MyApp`)
 
-> To respect the ability to install the same application in the same namespace, Katenary will create "variable" names like `{{ .Release.Name }}-servicename`. So, you will need to use some labels inside your docker-compose file to help katenary to build a correct helm chart.

-What can be interpreted by Katenary:
-
-- Services with "image" section (cannot work with "build" section)
-- **Named Volumes** are transformed to persistent volume claims - note that local volume will break the transformation to Helm Chart because there is (for now) no way to make it working (see below for resolution)
-- if `ports` and/or `expose` section, katenary will create Services and bind the port to the corresponding container port
-- `depends_on` will add init containers to wait for the depending service (using the first port)
-- `env_file` list will create a configMap object per environemnt file (⚠ todo: the "to-service" label doesn't work with configMap for now)
-- some labels can help to bind values, for example:
-    - `katenary.io/ingress: 80` will expose the port 80 in a ingress
-    - `katenary.io/to-service: VARNAME` will convert the value to a variable `{{ .Release.Name }}-VARNAME` - it's usefull when you want to pass the name of a service as a variable (think about the service name for mysql to pass to a container that wants to connect to this)

-- `katenary.io/env-to-service` binds the given (coma separated) variables names  to {{ .Release.Name }}-value
-- `katenary.io/ingress`: create an ingress and bind it to the given port
-- `katenary.io/secret-envfiles`: force the creation of a secret for the given coma separated list of "env_file"
-- `katenary.io/ports` is a coma separated list of ports if you want to avoid the "ports" section in your docker-compose for any reason
-- `katenary.io/configma-volumes` is a coma separated list of directory (should be declared as volumes also) to transform to a configMap object 
+These labels could be found by `katenary help-labels`, and can be placed as labels inside your docker-compose file:
+
+```text
+To get more information about a label, use `katenary help-label <name_without_prefix>
+e.g. katenary help-label dependencies
+
+katenary.v3/configmap-files:	[]string			Inject files as Configmap.
+katenary.v3/cronjob:		object				Create a cronjob from the service.
+katenary.v3/dependencies:	[]object			Add Helm dependencies to the service.
+katenary.v3/description:	string				Description of the service
+katenary.v3/env-from:		[]string			Add environment variables from another service.
+katenary.v3/exchange-volumes:	[]object			Add exchange volumes (empty directory on the node) to share data
+katenary.v3/health-check:	object				Health check to be added to the deployment.

+katenary.v3/ingress:		object				Ingress rules to be added to the service.

+katenary.v3/values-from:	map[string]string		Add values from another service.
+```
+
+## Katenary.yaml file and schema validation
+
+Instead of using labels inside the docker-compose file, you can use a `katenary.yaml` file to define the labels. This
+file is simpler to read and maintain, but you need to keep it up-to-date with the docker-compose file.
+
+For example, instead of using this:
+
+```yaml
+services:
+    web:
+        image: nginx:latest
+        katenary.v3/ingress: |-
+            hostname: myapp.example.com
+            port: 80
+```
+
+You can remove the labels, and use a `katenary.yaml` file:
+
+```yaml
+web:
+    ingress:
+        hostname: myapp.example.com
+        port: 80
+```
+
+To validate the `katenary.yaml` file, you can use the JSON schema using the "master" raw content:
+
+`https://repo.katenary.io/Katenary/katenary/raw/branch/master/katenary.json`
+
+It's easy to configure in [LazyVim](https://www.lazyvim.org/), using `nvim-lspconfig`,
+create a Lua file in your `plugins` directory, or apply the settings as the example below:
+
+```lua
+-- yaml.lua
+
+return {
+  {
+    "neovim/nvim-lspconfig",
+    opts = {
+      servers = {
+        yamlls = {
+          settings = {
+            yaml = {
+              schemas = {
+                ["https://repo.katenary.io/Katenary/katenary/raw/branch/master/katenary.json"] = "katenary.yaml",
+              },
+            },
+          },
+        },
+      },
+    },
+  },
+}
+```
+
+Use this address to validate the `katenary.yaml` file in VSCode:
+
+```json
+{
+    "yaml.schemas": {
+        "https://repo.katenary.io/Katenary/katenary/raw/branch/master/katenary.json": "katenary.yaml"
+    }
+}
+```
+
+> You can, of course, replace the `master` with a specific tag or branch.
+
+## What a name…
+
+Katenary is the stylized name of the project that comes from the "catenary" word.
+
+A catenary is a curve formed by a wire, rope, or chain hanging freely from two points that are not in the same vertical
+line. For example, the anchor chain between a boat and the anchor.
+
+This curved link represents what we try to do, the project is a stretched link from docker-compose to helm chart.

+# How Katenary works behind the scene
+
+This section is for developers who want to take part in Katenary. Here we describe how it works and the expected
+principles.
+
+## A few important points
+
+Katenary is developed in Go. The version currently supported is 1.20. For reasons of readability, the `any` type is
+preferred to `interface{}`.
+
+Since version v3, Katenary uses, in addition to `go-compose`, the `k8s` library to generate objects that are guaranteed
+to work before transformation. Katenary adds Helm syntax entries to add loops, transformations, and conditions.
+
+We really try to follow best practices and code principles. But, Katenary needs a lot of workarounds and string
+manipulation during the process. There are, also, some drawbacks using standard k8s packages that make a lot of type
+checks when generating the objects. We need to finalize the values after object generation.
+
+**This makes the coding a bit harder than simply converting from YAML to YAML.**
+
+> If Katenary only generated YAML objects, the algorithms would be much simpler and would require less generation work.
+
+## General principle
+
+During conversion, the `generator` package is primarily responsible for creating "objects". The principle is to generate
+one `Deployment` per `compose` service. If the container coming from "compose" exposes ports (explicitly), then a
+service is created.
+
+```mermaid
+flowchart TD
+
+    D[Deployment]:::outputs@{shape: curv-trap}
+    C[Container List]@{shape: docs}
+    ConfigMap:::outputs@{shape: curv-trap}
+    Secrets:::outputs@{shape: curv-trap}
+    H[Helm Chart.yaml file]:::outputs@{shape: curv-trap}
+    Val[Values files]:::outputs@{shape: curv-trap}
+    PVC:::outputs@{shape: curv-trap}
+    S[Service]:::outputs@{shape: curv-trap}
+    
+    A[Compose file]:::inputs --> B[Compose parser]
+    B --> G[Generator]
+    G --> P[Ports exposed to services] ---> S
+    G ------> H
+    G --> C --> D
+    G ------> Val
+    G ....-> M[Merge Continainers if same-pod] 
+    M ..-> C
+    G --> E[Environment variables] ----> Secrets & ConfigMap
+    G--> V[Bind volumes] -------> PVC
+    V -----> CF[ Create ConfigMap\nfor static files as\nconfigmap-files] --> ConfigMap
+
+    Secrets & ConfigMap -- create envFrom --> D
+    V -- bind volumes --> D
+    
+```
+
+If the declaration of a container is to be integrated into another pod (via the `same-pod` label), this `Deployment` and
+its associated service are still created. They are deleted last, once the merge has been completed.
+
+## Conversion in "`generator`" package
+
+The `generator` package is where object struct are defined, and where you can find the `Generate()` function.
+
+The generation fills `HelmChart` object using a loop:
+
+```golang
+for _, service := range project.Services {
+    dep := NewDeployment(service)
+    y, _ := dep.Yaml()
+    chart.Templates[dep.Filename()] = &ChartTemplate{
+        Content: y,
+        Servicename: service.Name,
+    }
+}
+```
+
+**A lot** of string manipulations are made by each `Yaml()` methods. This is where you find the complex and impacting
+operations. The `Yaml` methods **don't return a valid YAML content**. This is a Helm Chart YAML content with template
+conditions, values and calls to helper templates.
+
+> The `Yaml()` methods, in each object, need contribution, help, fixes, enhancements... They work, but there is a lot of
+> complexity. Please, create issues, pull-requests and conversation in the GitHub repository.
+
+The final step, before sending all templates to chart, is to bind the containers inside the same pod where it's
+specified.
+
+For each source container linked to the destination:
+
+- we get the deployment of the source
+- we copy the container to the destination deployment
+- we get the associated service (if any)
+- we then copy the service port to the destination service
+- we finally remove the source service and deployment
+
+> The `Configmap`, secrets, variables... are kept.
+
+It finally computes the `helper` file.
+
+## Conversion command
+
+The `generator` works the same as described above. But the "convert" command makes some final steps:
+
+- generate `values.yaml` and `Chart.yaml` files from the `HelmChart` object
+- add comments to the `values.yaml` files
+- add comments to the `Chart.yaml` files

+# Why those dependencies?
+
+Katenary uses `compose-go` and several Kubernetes official packages.
+
+- `github.com/compose-spec/compose-go`: to parse compose files. It ensures :
+    - that the project respects the "compose" specification
+    - that Katenary uses the "compose" struct exactly the same way `podman compose` or `docker compose` does
+- `github.com/spf13/cobra`: to parse command line arguments, sub-commands and flags. It also generates completion for
+  bash, zsh, fish and PowerShell.
+- `github.com/thediveo/netdb`: to get the standard names of a service from its port number
+- `gopkg.in/yaml.v3`:
+    - to generate `Chart.yaml` and `values.yaml` files (only)
+    - to parse Katenary labels in the compose file
+- `k8s.io/api` and `k8s.io/apimachinery` to create Kubernetes objects
+- `sigs.k8s.io/yaml`: to generate Katenary YAML files in the format of Kubernetes objects
+
+There are also some other packages used in the project, like `gopkg.in/yaml` to parse labels. I'm sorry to not list the
+entire dependencies. You can check the `go.mod` file to see all the dependencies.

+# Frequently Asked Questions
+
+## Why Katenary?
+
+The main author[^1] of Katenary is a big fan of Podman, Docker and makes a huge use of Compose. He uses it a lot in his
+daily work. When he started to work with Kubernetes, he wanted to have the same experience as with Docker Compose.
+He wanted to have a tool that could convert his `docker-compose` files to Kubernetes manifests, but also to Helm charts.
+
+Kompose was a good option. But the lacks of some options and configuration for the output Helm chart made him think
+about creating a new tool. He wanted to have a tool that could generate a complete Helm chart, with a lot of options
+and flexibility.
+
+[^1]: I'm talking about myself :sunglasses: - Patrice FERLET, aka Metal3d, Tech Lead and DevOps Engineer at Klee Group.
+
+## What's the difference between Katenary and Kompose?
+
+[Kompose](https://kompose.io/) is a very nice tool, made by the Kubernetes community. It's a tool to convert
+`docker-compose` files to Kubernetes manifests. It's a very good tool, and it's more mature than Katenary.
+
+Kompose is able to generate Helm charts, but [it could be not the case in future releases](https://github.com/kubernetes/kompose/issues/1716) for several reasons[^2].
+
+[^2]:
+    The author of Kompose explains that they have no bandwidth to maintain the Helm chart generation. It's a complex
+    task, and we can confirm. Katenary takes a lot of time to be developed and maintained. This issue mentions Katenary as
+    an alternative to Helm chart generation :smile:
+
+The project is focused on Kubernetes manifests and proposes to use "Kustomize" to adapt the manifests. Helm seems to be
+not the priority.
+
+Anyway, before this decision, the Helm chart generation was not what we expected. We wanted to have a more complete
+chart, with more options and more flexibility.
+
+> That's why we decided to create Katenary.
+
+Kompose didn't manage to generate a values file, complex volume binding, and many other things. It was also not able
+to manage dependencies between services.
+
+> Be sure that we don't want to compete with Kompose. We just want to propose a different approach to the problem.
+
+Kompose is an excellent tool, and we use it in some projects. It's a good choice if you want to convert
+your `docker-compose` files to Kubernetes manifests, but if you want to use Helm, Katenary is the tool you need.
+
+## Why not using "one label" for all the configuration?
+
+That was a discussion I had with my colleagues. The idea was to use a single label to store all the configuration.
+But, it's not a good idea.
+
+Sometimes, you will have a long list of things to configure, like ports, ingress, dependencies, etc. It's better to have
+a clear and readable configuration. Segmented labels are easier to read and to maintain. It also avoids having too
+many indentation levels in the YAML file.
+
+It is also more flexible. You can add or remove labels without changing the others.
+
+## Why not using a configuration file?
+
+The idea was to keep the configuration at a same place, and using the go-compose library to read the labels. It's
+easier to have a single file to manage.
+
+By the way, Katenary auto accepts a `compose.katenary.yaml` file in the same directory. It's a way to separate the
+configuration from the compose file. It uses
+the [overrides' mechanism](https://docs.docker.com/compose/multiple-compose-files/merge/) like "compose" does.
+
+## Why not developing with Rust?
+
+Seriously...
+
+OK, I will answer.
+
+Rust is a good language. But, Podman, Docker, Kubernetes, Helm, and mostly all technologies around Kubernetes are
+written in Go. We have a large ecosystem in Go to manipulate, read, and write Kubernetes manifests as parsing
+Compose files.
+
+> Go is better for this task.
+
+There is no reason to use Rust for this project.
+
+## Any chance to have a GUI?
+
+Yes, it's a possibility. But, it's not a priority. We have a lot of things to do before. We need to stabilize the
+project, to have a good documentation, to have a good test coverage, and to have a good community.
+
+But, in a not so far future, we could have a GUI. The choice of [Fyne.io](https://fyne.io) is already made, and we
+tested some concepts.
+
+## I'm rich (or not), I want to help you. How can I do?
+
+You can help us in many ways.
+
+- The first things we really need, more than money, more than anything else, is to have feedback. If you use Katenary,
+  if you have some issues, if you have some ideas, please open an issue on the [GitHub repository](https://github.com/Katenary/katenary).
+- The second thing is to help us to fix issues. If you're a Go developer, or if you want to fix the documentation,
+  your help is greatly appreciated.
+- And then, of course, we need money, or sponsors.
+
+### If you're a company
+
+We will be happy to communicate your help by putting your logo on the website and in the documentation. You can sponsor
+us by giving us some money, or by giving us some time of your developers, or leaving us some time to work on the project.
+
+### If you're an individual
+
+All donators will be listed on the website and in the documentation. You can give us some money by using
+the [GitHub Sponsors]()
+
+All main contributors[^3] will be listed on the website and in the documentation.
+
+> If you want to be anonymous, please tell us.
+
+[^3]:
+    Main contributors are the people who have made a significant contribution to the project. It could be code,
+    documentation, or any other help. There is no defined rules, at this time, to evaluate the contribution.
+    It's a subjective decision.

+# Welcome to Katenary documentation
+
+🚀 Unleash Productivity with Katenary! 🚀
+
+Tired of manual conversions? Katenary harnesses the labels from your "compose" file to craft complete Helm Charts
+effortlessly, saving you time and energy.
+
+🛠️ Simple automated CLI: Katenary handles the grunt work, generating everything needed for seamless service binding
+and Helm Chart creation.
+
+💡 Effortless Efficiency: You only need to add labels when it's necessary to precise things. Then call `katenary convert`
+and let the magic happen.
+
+<div style="margin: auto" class="zoomable">
+![](statics/workflow.svg)
+</div>
+
+# What is it?
+
+Katenary is a tool made to help you to transform "compose" files (`compose.yaml`, `docker-compose.yml`,
+`podman-compose.yml`...) to complete and production ready [Helm Chart](https://helm.sh).
+
+You'll be able to deploy your project in [:material-kubernetes: Kubernetes](https://kubernetes.io) in a few seconds
+(of course, more if you need to tweak with labels).
+
+It uses your current file and optionally labels to configure the result.
+
+It's an open source project, under MIT license, originally partially developed at [Smile](https://www.smile.eu).
+
+Today, it's partially developed in collaboration with [Klee Group](https://www.kleegroup.com). Note that Katenary is
+and **will stay an open source and free (as freedom) project**. We are convinced that the best way to make it better is to
+share it with the community.

+
+## Install Katenary
+
+Katenary is developed using the :fontawesome-brands-golang:{ .gopher } [Go](https://go.dev) language.
+The binary is statically linked, so you can simply download it from the [release
+page](https://github.com/Katenary/katenary/releases) of the project in GitHub.
+
+You need to select the right binary for your operating system and architecture, and copy the binary in a directory
+that is in your `PATH`.
+
+If you are a Linux user, you can use the "one line installation command" which will download the binary in your
+`$HOME/.local/bin` directory if it exists.
+
+```bash
+sh <(curl -sSL https://repo.katenary.io/Katenary/katenary/raw/branch/master/install.sh)
+```
+
+!!! Info "Upgrading is integrated to the `katenary` command"
+Katenary propose a `upgrade` sub-command to update the current binary to the latest stable release.
+
+    Of course, you need to install Katenary once :smile:
+
+!!! Note "You prefer to compile it, no need to install Go"
+You can also build and install it yourself, the provided Makefile has got a `build` command that uses `podman` or
+`docker` to build the binary.
+
+    So, you don't need to install Go compiler :+1:.
+
+    But, note that the "master" branch is not the "stable" version. It's preferable to switch to a tag, or to use the
+    releases.
+
+To compile it, you can use the following commands:
+
+```bash
+git clone https://repo.katenary.io/Katenary/katenary.git
+cd katenary
+make build
+make install
+```
+
+`make install` copies `./katenary` binary to your user binary path (`~/.local/bin`)
+
+You can install it in other directory by changing the `PREFIX` variable. E.g.:
+
+```bash
+make build
+sudo make install PREFIX=/usr/local
+```
+
+Check if everything is OK using `katenary version` and / or `katenary help`
+
+## Install completion
+
+Katenary uses the very nice project named `cobra` to manage flags, argument and auto-completion.
+
+You can activate it with:
+
+```bash
+# replace "bash" by "zsh" if needed
+source <(katenary completion bash)
+```
+
+Add this line in you `~/.profile`, `~/.bash_aliases` or `~/.bashrc` file to have completion at startup.
+
+## What a name
+
+A catenary is the curve that a hanging chain or cable assumes under its own weight when supported only at its ends.
+I, the maintainer, decided to name "Katenary" this project because it's like a chain that links a boat to a dock.
+Making the link between the "compose" world and the "Kubernetes" world is the main goal of this project.
+
+Anyway, it's too late to change the name now :smile:
+
+!!! Note "But I like this name!"
+
+    I spent time to find it :wink:
+
+## Special thanks to
+
+I really want to thank all the contributors, testers, and of course, the authors of the packages and tools that are used
+in this project. There is too many to list here. Katenary can work because of all these people. Open source is a great
+thing! :heart:

+# Labels documentation
+
+Katenary proposes labels to set in `compose.yaml` files (or override files) to configure the Helm Chart generation.
+Because it is sometimes needed to have structured values, it is necessary to use the YAML syntax.
+While compose labels are string, we can use _here-doc_ syntax using `|` to use YAML multiline as value.
+
+```yaml
+label-name: |-
+    # this is actually a multiline string here
+    key1: value1
+    key2: value2
+```
+
+Katenary will try to _Unmarshal_ these labels.
+

+## Detailed description
+
+<!-- START_DETAILED_DOC : do not remove this tag !-->
+### katenary.v3/configmap-files
+
+Inject files as Configmap.
+
+**Type**:  `[]string`
+
+It makes a file or directory to be converted to one or more ConfigMaps 
+and mounted in the pod. The file or directory is relative to the 
+service directory.
+
+If it is a directory, all files inside it are added to the ConfigMap.
+
+If the directory as subdirectories, so one configmap per subpath are created.
+
+!!! Warning
+    It is not intended to be used to store an entire project in configmaps.
+    It is intended to be used to store configuration files that are not managed 
+    by the application, like nginx configuration files. Keep in mind that your
+    project sources should be stored in an application image or in a storage.
+
+**Example:**
+
+```yaml
+volumes
+  - ./conf.d:/etc/nginx/conf.d
+labels:
+  katenary.v3/configmap-files: |-
+    - ./conf.d
+```
+
+
+### katenary.v3/cronjob
+
+Create a cronjob from the service.
+
+**Type**:  `object`
+
+This adds a cronjob to the chart.
+
+The label value is a YAML object with the following attributes:
+- command: the command to be executed 
+- schedule: the cron schedule (cron format or @every where "every" is a 
+  duration like 1h30m, daily, hourly...)
+- rbac: false (optionnal), if true, it will create a role, a rolebinding and
+  a serviceaccount to make your cronjob able to connect the Kubernetes API
+
+**Example:**
+
+```yaml
+labels:
+    katenary.v3/cronjob: |-
+        command: echo "hello world"
+        schedule: "* */1 * * *" # or @hourly for example
+```
+
+
+### katenary.v3/dependencies
+
+Add Helm dependencies to the service.
+
+**Type**:  `[]object`
+
+Set the service to be, actually, a Helm dependency. This means that the 
+service will not be exported as template. The dependencies are added to 
+the Chart.yaml file and the values are added to the values.yaml file.
+
+It's a list of objects with the following attributes:
+
+- name: the name of the dependency
+- repository: the repository of the dependency
+- alias: the name of the dependency in values.yaml (optional)
+- values: the values to be set in values.yaml (optional)
+
+!!! Info
+    Katenary doesn't update the helm depenedencies by default.
+    
+    Use `--helm-update` (or `-u`) flag to update the dependencies.
+    
+    example: <code>katenary convert -u</code>
+
+By setting an alias, it is possible to change the name of the dependency 
+in values.yaml.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/dependencies: |-
+    - name: mariadb
+      repository: oci://registry-1.docker.io/bitnamicharts
+
+      ## optional, it changes the name of the section in values.yaml
+      # alias: mydatabase
+
+      ## optional, it adds the values to values.yaml
+      values:
+        auth:
+          database: mydatabasename
+          username: myuser
+          password: the secret password
+```
+
+
+### katenary.v3/description
+
+Description of the service
+
+**Type**:  `string`
+
+This replaces the default comment in values.yaml file to the given description. 
+It is useful to document the service and configuration.
+
+The value can be set with a documentation in multiline format.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/description: |-
+    This is a description of the service.
+    It can be multiline.
+```
+
+
+### katenary.v3/env-from
+
+Add environment variables from another service.
+
+**Type**:  `[]string`
+
+It adds environment variables from another service to the current service.
+
+**Example:**
+
+```yaml
+service1:
+  image: nginx:1.19
+  environment:
+      FOO: bar
+
+service2:
+  image: php:7.4-fpm
+  labels:
+    # get the congigMap from service1 where FOO is 
+    # defined inside this service too
+    katenary.v3/env-from: |-
+        - myservice1
+```
+
+
+### katenary.v3/exchange-volumes
+
+Add exchange volumes (empty directory on the node) to share data
+
+**Type**:  `[]object`
+
+This label allows sharing data between containres. The volume is created in 
+the node and mounted in the pod. It is useful to share data between containers
+in a "same pod" logic. For example to let PHP-FPM and Nginx share the same direcotory.
+
+This will create:
+
+- an `emptyDir` volume in the deployment
+- a `voumeMount` in the pod for **each container**
+- a `initContainer` for each definition
+
+Fields:
+  - name: the name of the volume (manadatory)
+  - mountPath: the path where the volume is mounted in the pod (optional, default is `/opt`)
+  - init: a command to run to initialize the volume with data (optional)
+
+!!! Warning
+    This is highly experimental. This is mainly useful when using the "same-pod" label.
+
+**Example:**
+
+```yaml
+nginx:
+  # ...
+  labels;
+    katenary.v3/exchange-volumes: |-
+      - name: php-fpm
+        mountPath: /var/www/html
+php:
+  # ...
+  labels:
+    katenary.v3/exchange-volumes: |-
+      - name: php-fpm
+        mountPath: /opt
+        init: cp -ra /var/www/html/* /opt
+```
+
+
+### katenary.v3/health-check
+
+Health check to be added to the deployment.
+
+**Type**:  `object`
+
+Health check to be added to the deployment.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/health-check: |-
+    livenessProbe:
+      httpGet:
+        path: /health
+        port: 8080
+```
+
+
+### katenary.v3/ignore
+
+Ignore the service
+
+**Type**:  `bool`
+
+Ingoring a service to not be exported in helm chart.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/ignore: "true"
+```
+
+
+### katenary.v3/ingress
+
+Ingress rules to be added to the service.
+
+**Type**:  `object`
+
+Declare an ingress rule for the service. The port should be exposed or 
+declared with `katenary.v3/ports`.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/ingress: |-
+    port: 80
+    hostname: mywebsite.com (optional)
+```
+
+
+### katenary.v3/main-app
+
+Mark the service as the main app.
+
+**Type**:  `bool`
+
+This makes the service to be the main application. Its image tag is 
+considered to be the Chart appVersion and to be the defaultvalue in Pod
+container image attribute.
+
+!!! Warning
+    This label cannot be repeated in others services. If this label is
+    set in more than one service as true, Katenary will return an error.
+
+**Example:**
+
+```yaml
+ghost:
+  image: ghost:1.25.5
+  labels:
+    # The chart is now named ghost, and the appVersion is 1.25.5.
+    # In Deployment, the image attribute is set to ghost:1.25.5 if 
+    # you don't change the "tag" attribute in values.yaml
+    katenary.v3/main-app: true
+```
+
+
+### katenary.v3/map-env
+
+Map env vars from the service to the deployment.
+
+**Type**:  `map[string]string`
+
+Because you may need to change the variable for Kubernetes, this label
+forces the value to another. It is also particullary helpful to use a template 
+value instead. For example, you could bind the value to a service name 
+with Helm attributes:
+`{{ tpl .Release.Name . }}`.
+
+If you use `__APP__` in the value, it will be replaced by the Chart name.
+
+**Example:**
+
+```yaml
+env:
+  DB_HOST: database
+  RUNNING: docker
+  OTHER: value
+labels:
+  katenary.v3/map-env: |-
+    RUNNING: kubernetes
+    DB_HOST: '{{ include "__APP__.fullname" . }}-database'
+```
+
+
+### katenary.v3/ports
+
+Ports to be added to the service.
+
+**Type**:  `[]uint32`
+
+Only useful for services without exposed port. It is mandatory if the 
+service is a dependency of another service.
+
+**Example:**
+
+```yaml
+labels:
+  katenary.v3/ports: |-
+    - 8080
+    - 8081
+```
+
+
+### katenary.v3/same-pod
+
+Move the same-pod deployment to the target deployment.
+
+**Type**:  `string`
+
+This will make the service to be included in another service pod. Some services 
+must work together in the same pod, like a sidecar or a proxy or nginx + php-fpm.
+
+Note that volume and VolumeMount are copied from the source to the target 
+deployment.
+
+**Example:**
+
+```yaml
+web:
+  image: nginx:1.19
+
+php:
+  image: php:7.4-fpm
+  labels:
+    katenary.v3/same-pod: web
+```
+
+
+### katenary.v3/secrets
+
+Env vars to be set as secrets.
+
+**Type**:  `[]string`
+
+This label allows setting the environment variables as secrets. The variable 
+is removed from the environment and added to a secret object.
+
+The variable can be set to the `katenary.v3/values` too,
+so the secret value can be configured in values.yaml
+
+**Example:**
+
+```yaml
+env:
+  PASSWORD: a very secret password
+  NOT_A_SECRET: a public value
+labels:
+  katenary.v3/secrets: |-
+    - PASSWORD
+```
+
+
+### katenary.v3/values
+
+Environment variables to be added to the values.yaml
+
+**Type**:  `[]string or map[string]string`
+
+By default, all environment variables in the "env" and environment
+files are added to configmaps with the static values set. This label
+allows adding environment variables to the values.yaml file.
+
+Note that the value inside the configmap is `{{ tpl vaname . }}`, so 
+you can set the value to a template that will be rendered with the 
+values.yaml file.
+
+The value can be set with a documentation. This may help to understand 
+the purpose of the variable.
+
+**Example:**
+
+```yaml
+env:
+  FOO: bar
+  DB_NAME: mydb
+  TO_CONFIGURE: something that can be changed in values.yaml
+  A_COMPLEX_VALUE: example
+labels:
+  katenary.v3/values: |-
+    # simple values, set as is in values.yaml
+    - TO_CONFIGURE
+    # complex values, set as a template in values.yaml with a documentation
+    - A_COMPLEX_VALUE: |-
+        This is the documentation for the variable to 
+        configure in values.yaml.
+        It can be, of course,  a multiline text.
+```
+
+
+### katenary.v3/values-from
+
+Add values from another service.
+
+**Type**:  `map[string]string`
+
+This label allows adding values from another service to the current service.
+It avoid duplicating values, environment or secrets that should be the same.
+
+The key is the value to be added, and the value is the "key" to fetch in the
+form `service_name.environment_name`.
+
+**Example:**
+
+```yaml
+database:
+  image: mariadb:10.5
+  environment:
+    MARIADB_USER: myuser
+    MARIADB_PASSWORD: mypassword
+  labels:
+    # we can declare secrets
+    katenary.v3/secrets: |-
+      - MARIADB_PASSWORD
+php:
+  image: php:7.4-fpm
+  environment:
+    # it's duplicated in docker / podman
+    DB_USER: myuser
+    DB_PASSWORD: mypassword
+  labels:
+    # removes the duplicated, use the configMap and secrets from "database"
+    katenary.v3/values-from: |-
+      DB_USER: database.MARIADB_USER
+      DB_PASSWORD: database.MARIADB_PASSWORD
+```

+Package generator generates kubernetes objects from a "compose" file and transforms them into a helm chart.
+
+The generator package is the core of katenary. It is responsible for generating kubernetes objects from a compose file and transforming them into a helm chart. Conversion manipulates Yaml representation of kubernetes object to add conditions, labels, annotations, etc. to the objects. It also create the values to be set to the values.yaml file.
+
+The generate.Convert\(\) create an HelmChart object and call "Generate\(\)" method to convert from a compose file to a helm chart. It saves the helm chart in the given directory.
+
+If you want to change or override the write behavior, you can use the HelmChart.Generate\(\) function and implement your own write function. This function returns the helm chart object containing all kubernetes objects and helm chart ingormation. It does not write the helm chart to the disk.

+# Basic Usage
+
+Basically, you can use `katenary` to transpose a docker-compose file (or any compose file compatible with
+`podman-compose` and `docker-compose`) to a configurable Helm Chart. This resulting helm chart can be installed with
+`helm` command to your Kubernetes cluster.
+
+For very basic compose files, without any specific configuration, Katenary will create a working helm chart using the
+simple command line:
+
+```bash
+katenary convert
+```
+
+This will create a `chart` directory with the helm chart inside.
+
+But, in general, you will need to add a few configurations to help Katenary to transpose the compose file to a working
+helm chart.
+
+There are two ways to configure Katenary:
+
+- Using the compose files, adding labels to the services
+- Using a specific file named `katenary.yaml`
+
+The Katenary file `katenary.yaml` has benefits over the labels in the compose file:
+
+- you can validate the configuration with a schema, and use completion in your editor
+- you separate the configuration and leave the compose file "intact"
+- the syntax is a bit simpler, instead of using `katenary.v3/xxx: |-` you can use `xxx: ...`
+
+But: **this implies that you have to maintain two files if the compose file changes.**
+
+For example. With "labels", you should do:
+
+```yaml
+# in compose file
+services:
+    webapp:
+        image: php:7-apache
+        ports:
+            - 8080:80
+        environment:
+            DB_HOST: database
+        labels:
+        katenary.v3/ingress: |-
+            hostname: myapp.example.com
+            port: 8080
+        katenary.v3/map-env: |-
+            DB_HOST: "{{ .Release.Name }}-database"
+```
+
+Using a Katenary file, you can do:
+
+```yaml
+# in compose file, no need to add labels
+services:
+    webapp:
+        image: php:7-apache
+        ports:
+            - 8080:80
+        environment:
+            DB_HOST: database
+
+# in katenary.yaml
+webapp:
+    ingress:
+        hostname: myapp.example.com
+        port: 8080
+
+    map-env:
+        DB_HOST: "{{ .Release.Name }}-database"
+```
+
+!!! Warning "YAML in multiline label"
+
+    Compose only accept text label. So, to put a complete YAML content in the target label,
+    you need to use a pipe char (`|` or `|-`) and to **indent** your content.
+
+    For example :
+
+    ```yaml
+      labels:
+        # your labels
+        foo: bar
+        # katenary labels with multiline
+        katenary.v3/ingress: |-
+          hostname: my.website.tld
+          port: 80
+        katenary.v3/ports: |-
+          - 1234
+    ```
+
+Katenary transforms compose services this way:
+
+- Takes the service and create a "Deployment" file
+- if a port is declared, Katenary creates a service (`ClusterIP`)
+- if a port is exposed, Katenary creates a service (`NodePort`)
+- environment variables will be stored inside a `ConfigMap`
+- image, tags, and ingresses configuration are also stored in `values.yaml` file
+- if named volumes are declared, Katenary create `PersistentVolumeClaims` - not enabled in values file
+- `depends_on` needs that the pointed service declared a port. If not, you can use labels to inform Katenary
+
+For any other specific configuration, like binding local files as `ConfigMap`, bind variables, add values with
+documentation, etc. You'll need to use labels.
+
+Katenary can also configure containers grouping in pods, declare dependencies, ignore some services, force variables as
+secrets, mount files as `configMap`, and many others things. To adapt the helm chart generation, you will need to use
+some specific labels.
+
+For more complete label usage, see [the labels page](labels.md).
+
+!!! Info "Overriding file"
+
+    It could be sometimes more convinient to separate the
+    configuration related to Katenary inside a secondary file.
+
+    Instead of adding labels inside the `compose.yaml` file,
+    you can create a file named `compose.katenary.yaml` and
+    declare your labels inside. Katenary will detect it by
+    default.
+
+    **No need to precise the file in the command line.**
+
+## Make conversion
+
+After having installed `katenary`, the standard usage is to call:
+
+    katenary convert
+
+It will search standard compose files in the current directory and try to create a helm chart in "chart" directory.
+
+!!! Info
+Katenary uses the compose-go library which respects the Docker and Docker-Compose specification. Keep in mind that
+it will find files exactly the same way as `docker-compose` and `podman-compose` do it.
+
+Of course, you can provide others files than the default with (cumulative) `-c` options:
+
+    katenary convert -c file1.yaml -c file2.yaml
+
+## Some common labels to use
+
+Katenary proposes a lot of labels to configure the helm chart generation, but some are very important.
+
+!!! Info
+For more complete label usage, see [the labels page](labels.md).
+
+### Work with Depends On?
+
+Kubernetes does not provide service or pod starting detection from others pods. But Katenary will create `initContainer`
+to make you able to wait for a service to respond. But you'll probably need to adapt a bit the compose file.
+
+See this compose file:
+
+```yaml
+version: "3"
+
+services:
+    webapp:
+        image: php:8-apache
+        depends_on:
+            - database
+
+    database:
+        image: mariadb
+        environment:
+            MYSQL_ROOT_PASSWORD: foobar
+```
+
+In this case, `webapp` needs to know the `database` port because the `depends_on` points on it and Kubernetes has not
+(yet) solution to check the database startup. Katenary wants to create a `initContainer` to hit on the related service.
+So, instead of exposing the port in the compose definition, let's declare this to Katenary with labels:
+
+```yaml
+version: "3"
+
+services:
+    webapp:
+        image: php:8-apache
+        depends_on:
+            - database
+
+    database:
+        image: mariadb
+        environment:
+            MYSQL_ROOT_PASSWORD: foobar
+        labels:
+            katenary.v3/ports: |-
+                - 3306
+```
+
+### Declare ingresses
+
+It's very common to have an Ingress resource on web application to deploy on Kubernetes. It allows exposing the
+service to the outside of the cluster (you need to install an ingress controller).
+
+Katenary can create this resource for you. You just need to declare the hostname and the port to bind.
+
+```yaml
+services:
+    webapp:
+        image: ...
+        ports: 8080:5050
+        labels:
+            katenary.v3/ingress: |-
+                # the target port is 5050 wich is the "service" port
+                port: 5050
+                hostname: myapp.example.com
+```
+
+Note that the port to bind is the one used by the container, not the used locally. This is because Katenary create a
+service to bind the container itself.
+
+### Map environment to helm values
+
+A lot of framework needs to receive service host or IP in an environment variable to configure the connection. For
+example, to connect a PHP application to a database.
+
+With a compose file, there is no problem as Docker/Podman allows resolving the name by container name:
+
+```yaml
+services:
+    webapp:
+        image: php:7-apache
+        environment:
+            DB_HOST: database
+
+    database:
+        image: mariadb
+```
+
+Katenary prefixes the services with `{{ .Release.Name }}` (to make it possible to install the application several times
+in a namespace), so you need to "remap" the environment variable to the right one.
+
+```yaml
+services:
+    webapp:
+        image: php:7-apache
+        environment:
+            DB_HOST: database
+        labels:
+            katenary.v3/mapenv: |-
+                DB_HOST: "{{ .Release.Name }}-database"
+
+    database:
+        image: mariadb
+```
+
+This label can be used to map others environment for any others reason. E.g. to change an informational environment
+variable.
+
+```yaml
+services:
+    webapp:
+        #...
+        environment:
+            RUNNING: docker
+        labels:
+            katenary.v3/mapenv: |-
+                RUNNING: kubernetes
+```
+
+In the above example, `RUNNING` will be set to `kubernetes` when you'll deploy the application with helm, and it's
+`docker` for "Podman" and "Docker" executions.

+.TH "Katenary" "1" "2025-08-21" "mkdocs-manpage v2.0.1" "Katenary helm chart generator"
+.SH Basic Usage
+Basically, you can use \f[CR]katenary\f[R] to transpose a docker\-compose file (or any compose file compatible with \f[CR]podman\-compose\f[R] and \f[CR]docker\-compose\f[R]) to a configurable Helm Chart.
+This resulting helm chart can be installed with \f[CR]helm\f[R] command to your Kubernetes cluster.
+.PP
+For very basic compose files, without any specific configuration, Katenary will create a working helm chart using the simple command line:
+.IP
+.EX
+katenary convert
+.EE
+.PP
+This will create a \f[CR]chart\f[R] directory with the helm chart inside.
+.PP
+But, in general, you will need to add a few configurations to help Katenary to transpose the compose file to a working helm chart.
+.PP
+There are two ways to configure Katenary:
+.IP \[bu] 2
+Using the compose files, adding labels to the services
+.IP \[bu] 2
+Using a specific file named \f[CR]katenary.yaml\f[R]
+.PP
+The Katenary file \f[CR]katenary.yaml\f[R] has benefits over the labels in the compose file:
+.IP \[bu] 2
+you can validate the configuration with a schema, and use completion in your editor
+.IP \[bu] 2
+you separate the configuration and leave the compose file \[dq]intact\[dq]
+.IP \[bu] 2
+the syntax is a bit simpler, instead of using \f[CR]katenary.v3/xxx: |\-\f[R] you can use \f[CR]xxx: ...\f[R]
+.PP
+But: \f[B]this implies that you have to maintain two files if the compose file changes.\f[R]
+.PP
+For example.
+With \[dq]labels\[dq], you should do:
+.IP
+.EX
+# in compose file
+services:
+    webapp:
+        image: php:7\-apache
+        ports:
+            \- 8080:80
+        environment:
+            DB_HOST: database
+        labels:
+        katenary.v3/ingress: |\-
+            hostname: myapp.example.com
+            port: 8080
+        katenary.v3/map\-env: |\-
+            DB_HOST: \[dq]{{ .Release.Name }}\-database\[dq]
+.EE
+.PP
+Using a Katenary file, you can do:
+.IP
+.EX
+# in compose file, no need to add labels
+services:
+    webapp:
+        image: php:7\-apache
+        ports:
+            \- 8080:80
+        environment:
+            DB_HOST: database
+
+# in katenary.yaml
+webapp:
+    ingress:
+        hostname: myapp.example.com
+        port: 8080
+
+    map\-env:
+        DB_HOST: \[dq]{{ .Release.Name }}\-database\[dq]

+.PP
+YAML in multiline label
+.PP
+Compose only accept text label.
+So, to put a complete YAML content in the target label, you need to use a pipe char (\f[CR]|\f[R] or \f[CR]|\-\f[R]) and to \f[B]indent\f[R] your content.
+.PP
+For example :
+.IP

+  labels:
+    # your labels
+    foo: bar
+    # katenary labels with multiline

+It allows exposing the service to the outside of the cluster (you need to install an ingress controller).
+.PP
+Katenary can create this resource for you.
+You just need to declare the hostname and the port to bind.
+.IP
+.EX
+services:
+    webapp:
+        image: ...
+        ports: 8080:5050
+        labels:
+            katenary.v3/ingress: |\-
+                # the target port is 5050 wich is the \[dq]service\[dq] port
+                port: 5050
+                hostname: myapp.example.com
+.EE
+.PP
+Note that the port to bind is the one used by the container, not the used locally.
+This is because Katenary create a service to bind the container itself.
+.SS Map environment to helm values
+A lot of framework needs to receive service host or IP in an environment variable to configure the connection.
+For example, to connect a PHP application to a database.
+.PP
+With a compose file, there is no problem as Docker/Podman allows resolving the name by container name:
+.IP
+.EX
+services:
+    webapp:
+        image: php:7\-apache
+        environment:
+            DB_HOST: database
+
+    database:
+        image: mariadb
+.EE
+.PP
+Katenary prefixes the services with \f[CR]{{ .Release.Name }}\f[R] (to make it possible to install the application several times in a namespace), so you need to \[dq]remap\[dq] the environment variable to the right one.
+.IP
+.EX
+services:
+    webapp:
+        image: php:7\-apache
+        environment:
+            DB_HOST: database
+        labels:
+            katenary.v3/mapenv: |\-
+                DB_HOST: \[dq]{{ .Release.Name }}\-database\[dq]
+
+    database:
+        image: mariadb
+.EE
+.PP
+This label can be used to map others environment for any others reason.
+E.g.
+to change an informational environment variable.
+.IP
+.EX
+services:
+    webapp:
+        #...
+        environment:
+            RUNNING: docker
+        labels:
+            katenary.v3/mapenv: |\-
+                RUNNING: kubernetes
+.EE
+.PP
+In the above example, \f[CR]RUNNING\f[R] will be set to \f[CR]kubernetes\f[R] when you\[aq]ll deploy the application with helm, and it\[aq]s \f[CR]docker\f[R] for \[dq]Podman\[dq] and \[dq]Docker\[dq] executions.
+.SH Labels documentation
+Katenary proposes labels to set in \f[CR]compose.yaml\f[R] files (or override files) to configure the Helm Chart generation.
+Because it is sometimes needed to have structured values, it is necessary to use the YAML syntax.
+While compose labels are string, we can use \f[I]here\-doc\f[R] syntax using \f[CR]|\f[R] to use YAML multiline as value.
+.IP
+.EX
+label\-name: |\-
+    # this is actually a multiline string here
+    key1: value1
+    key2: value2
+.EE
+.PP
+Katenary will try to \f[I]Unmarshal\f[R] these labels.

+.SS Detailed description
+.SS katenary.v3/configmap\-files
+Inject files as Configmap.
+.PP
+\f[B]Type\f[R]: \f[CR][]string\f[R]
+.PP
+It makes a file or directory to be converted to one or more ConfigMaps and mounted in the pod.
+The file or directory is relative to the service directory.
+.PP
+If it is a directory, all files inside it are added to the ConfigMap.
+.PP
+If the directory as subdirectories, so one configmap per subpath are created.
+.PP
+Warning
+.PP
+It is not intended to be used to store an entire project in configmaps.
+It is intended to be used to store configuration files that are not managed by the application, like nginx configuration files.
+Keep in mind that your project sources should be stored in an application image or in a storage.
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX
+volumes
+  \- ./conf.d:/etc/nginx/conf.d
+labels:
+  katenary.v3/configmap\-files: |\-
+    \- ./conf.d
+.EE
+.SS katenary.v3/cronjob
+Create a cronjob from the service.
+.PP
+\f[B]Type\f[R]: \f[CR]object\f[R]
+.PP
+This adds a cronjob to the chart.
+.PP
+The label value is a YAML object with the following attributes: \- command: the command to be executed \- schedule: the cron schedule (cron format or \[at]every where \[dq]every\[dq] is a duration like 1h30m, daily, hourly...)
+\- rbac: false (optionnal), if true, it will create a role, a rolebinding and a serviceaccount to make your cronjob able to connect the Kubernetes API
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX
+labels:
+    katenary.v3/cronjob: |\-
+        command: echo \[dq]hello world\[dq]
+        schedule: \[dq]* */1 * * *\[dq] # or \[at]hourly for example
+.EE
+.SS katenary.v3/dependencies
+Add Helm dependencies to the service.
+.PP
+\f[B]Type\f[R]: \f[CR][]object\f[R]
+.PP
+Set the service to be, actually, a Helm dependency.
+This means that the service will not be exported as template.
+The dependencies are added to the Chart.yaml file and the values are added to the values.yaml file.
+.PP
+It\[aq]s a list of objects with the following attributes:
+.IP \[bu] 2
+name: the name of the dependency
+.IP \[bu] 2
+repository: the repository of the dependency
+.IP \[bu] 2
+alias: the name of the dependency in values.yaml (optional)
+.IP \[bu] 2
+values: the values to be set in values.yaml (optional)
+.PP
+Info
+.PP
+Katenary doesn\[aq]t update the helm depenedencies by default.
+.PP
+Use \f[CR]\-\-helm\-update\f[R] (or \f[CR]\-u\f[R]) flag to update the dependencies.
+.PP
+example: \f[CR]katenary convert \-u\f[R]
+.PP
+By setting an alias, it is possible to change the name of the dependency in values.yaml.
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX
+labels:
+  katenary.v3/dependencies: |\-
+    \- name: mariadb
+      repository: oci://registry\-1.docker.io/bitnamicharts
+
+      ## optional, it changes the name of the section in values.yaml
+      # alias: mydatabase
+
+      ## optional, it adds the values to values.yaml
+      values:
+        auth:
+          database: mydatabasename
+          username: myuser
+          password: the secret password
+.EE
+.SS katenary.v3/description
+Description of the service
+.PP
+\f[B]Type\f[R]: \f[CR]string\f[R]
+.PP
+This replaces the default comment in values.yaml file to the given description.
+It is useful to document the service and configuration.
+.PP
+The value can be set with a documentation in multiline format.
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX
+labels:
+  katenary.v3/description: |\-
+    This is a description of the service.

+.EE
+.SS katenary.v3/env\-from
+Add environment variables from another service.
+.PP
+\f[B]Type\f[R]: \f[CR][]string\f[R]
+.PP
+It adds environment variables from another service to the current service.
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX

+.EE
+.SS katenary.v3/exchange\-volumes
+Add exchange volumes (empty directory on the node) to share data
+.PP
+\f[B]Type\f[R]: \f[CR][]object\f[R]
+.PP
+This label allows sharing data between containres.
+The volume is created in the node and mounted in the pod.
+It is useful to share data between containers in a \[dq]same pod\[dq] logic.
+For example to let PHP\-FPM and Nginx share the same direcotory.
+.PP
+This will create:
+.IP \[bu] 2
+an \f[CR]emptyDir\f[R] volume in the deployment
+.IP \[bu] 2
+a \f[CR]voumeMount\f[R] in the pod for \f[B]each container\f[R]
+.IP \[bu] 2
+a \f[CR]initContainer\f[R] for each definition
+.PP
+Fields: \- name: the name of the volume (manadatory) \- mountPath: the path where the volume is mounted in the pod (optional, default is \f[CR]/opt\f[R]) \- init: a command to run to initialize the volume with data (optional)
+.PP
+Warning
+.PP
+This is highly experimental.
+This is mainly useful when using the \[dq]same\-pod\[dq] label.
+.PP
+\f[B]Example:\f[R]

+Ingress rules to be added to the service.
+.PP
+\f[B]Type\f[R]: \f[CR]object\f[R]
+.PP
+Declare an ingress rule for the service.
+The port should be exposed or declared with \f[CR]katenary.v3/ports\f[R].
+.PP
+\f[B]Example:\f[R]
+.IP
+.EX

+.EE
+.SS katenary.v3/main\-app
+Mark the service as the main app.
+.PP
+\f[B]Type\f[R]: \f[CR]bool\f[R]
+.PP
+This makes the service to be the main application.
+Its image tag is considered to be the Chart appVersion and to be the defaultvalue in Pod container image attribute.
+.PP
+Warning
+.PP
+This label cannot be repeated in others services.
+If this label is set in more than one service as true, Katenary will return an error.

+.EE
+.SS katenary.v3/map\-env
+Map env vars from the service to the deployment.
+.PP
+\f[B]Type\f[R]: \f[CR]map[string]string\f[R]
+.PP
+Because you may need to change the variable for Kubernetes, this label forces the value to another.
+It is also particullary helpful to use a template value instead.
+For example, you could bind the value to a service name with Helm attributes: \f[CR]{{ tpl .Release.Name . }}\f[R].
+.PP
+If you use \f[CR]__APP__\f[R] in the value, it will be replaced by the Chart name.

+.PP
+\f[B]Type\f[R]: \f[CR]string\f[R]
+.PP
+This will make the service to be included in another service pod.
+Some services must work together in the same pod, like a sidecar or a proxy or nginx + php\-fpm.
+.PP
+Note that volume and VolumeMount are copied from the source to the target deployment.
+.PP
+\f[B]Example:\f[R]

+.SS katenary.v3/secrets
+Env vars to be set as secrets.
+.PP
+\f[B]Type\f[R]: \f[CR][]string\f[R]
+.PP
+This label allows setting the environment variables as secrets.
+The variable is removed from the environment and added to a secret object.
+.PP
+The variable can be set to the \f[CR]katenary.v3/values\f[R] too, so the secret value can be configured in values.yaml
+.PP
+\f[B]Example:\f[R]

+Environment variables to be added to the values.yaml
+.PP
+\f[B]Type\f[R]: \f[CR][]string or map[string]string\f[R]
+.PP
+By default, all environment variables in the \[dq]env\[dq] and environment files are added to configmaps with the static values set.
+This label allows adding environment variables to the values.yaml file.
+.PP
+Note that the value inside the configmap is \f[CR]{{ tpl vaname . }}\f[R], so you can set the value to a template that will be rendered with the values.yaml file.
+.PP
+The value can be set with a documentation.
+This may help to understand the purpose of the variable.

+Package generator generates kubernetes objects from a "compose" file and transforms them into a helm chart.

+Conversion manipulates Yaml representation of kubernetes object to add conditions, labels, annotations, etc. to the
+objects. It also create the values to be set to the values.yaml file.
+
+The generate.Convert() create an HelmChart object and call "Generate()" method to convert from a compose file to a helm

+
+If you want to change or override the write behavior, you can use the HelmChart.Generate() function and implement your
+own write function. This function returns
+the helm chart object containing all kubernetes objects and helm chart ingormation. It does not write the helm chart to

+A katenary file, named "katenary.yml" or "katenary.yaml", is a file where you can define the
+configuration of the conversion avoiding the use of labels in the compose file.
+
+Formely, the file describe the same structure as in labels, and so that can be validated and

+# To create a label documentation:

+# "labelname":
+#   type: the label type (bool, string, array, object...)
+#   short: a short description
+#   long: |-
+#     A multiline description to explain the label behavior

+#     yamlsyntax: here
+#
+# This file is embed in the Katenary binary and parsed in kanetaryLabels.go init() function.
+#
+# Note:
+# - The short and long texts are parsed with text/template, so you can use template syntax.
+#   That means that if you want to display double brackets, you need to enclose them to
+#   prevent template to try to expand the content, for example :
+#   This is an {{ "{{ example }}" }}.
+#
+#   This will display "This is an {{ exemple }}" in the output.
+# - Use {{ .KatenaryPrefix }} to let Katenary replace it with the label prefix (e.g. "katenary.v3")
+
+"main-app":
+  short: "Mark the service as the main app."
+  long: |-
+    This makes the service to be the main application. Its image tag is 
+    considered to be the Chart appVersion and to be the defaultvalue in Pod
+    container image attribute.
+
+    !!! Warning
+        This label cannot be repeated in others services. If this label is
+        set in more than one service as true, Katenary will return an error.
+  example: |-
+    ghost:
+      image: ghost:1.25.5
+      labels:
+        # The chart is now named ghost, and the appVersion is 1.25.5.
+        # In Deployment, the image attribute is set to ghost:1.25.5 if 
+        # you don't change the "tag" attribute in values.yaml
+        {{ .KatenaryPrefix }}/main-app: true
+  type: "bool"
+
+"values":
+  short: "Environment variables to be added to the values.yaml"
+  long: |-
+    By default, all environment variables in the "env" and environment
+    files are added to configmaps with the static values set. This label
+    allows adding environment variables to the values.yaml file.
+
+    Note that the value inside the configmap is {{ "{{ tpl vaname . }}" }}, so 
+    you can set the value to a template that will be rendered with the 
+    values.yaml file.
+
+    The value can be set with a documentation. This may help to understand 
+    the purpose of the variable.
+  example: |-
+    env:
+      FOO: bar
+      DB_NAME: mydb
+      TO_CONFIGURE: something that can be changed in values.yaml
+      A_COMPLEX_VALUE: example
+    labels:
+      {{ .KatenaryPrefix }}/values: |-
+        # simple values, set as is in values.yaml
+        - TO_CONFIGURE
+        # complex values, set as a template in values.yaml with a documentation
+        - A_COMPLEX_VALUE: |-
+            This is the documentation for the variable to 
+            configure in values.yaml.
+            It can be, of course,  a multiline text.
+  type: "[]string or map[string]string"
+
+"secrets":
+  short: "Env vars to be set as secrets."
+  long: |-
+    This label allows setting the environment variables as secrets. The variable 
+    is removed from the environment and added to a secret object.
+
+    The variable can be set to the {{ printf "%s/%s" .KatenaryPrefix "values"}} too,
+    so the secret value can be configured in values.yaml
+  example: |-
+    env:
+      PASSWORD: a very secret password
+      NOT_A_SECRET: a public value
+    labels:
+      {{ .KatenaryPrefix }}/secrets: |-
+        - PASSWORD
+  type: "[]string"
+
+"ports":
+  short: "Ports to be added to the service."
+  long: |-
+    Only useful for services without exposed port. It is mandatory if the 
+    service is a dependency of another service.
+  example: |-
+    labels:
+      {{ .KatenaryPrefix }}/ports: |-
+        - 8080
+        - 8081
+  type: "[]uint32"
+
+"ingress":
+  short: "Ingress rules to be added to the service."
+  long: |-
+    Declare an ingress rule for the service. The port should be exposed or 
+    declared with {{ printf "%s/%s" .KatenaryPrefix "ports" }}.
+  example: |-
+    labels:
+      {{ .KatenaryPrefix }}/ingress: |-
+        port: 80
+        hostname: mywebsite.com (optional)
+  type: "object"
+
+"map-env":
+  short: "Map env vars from the service to the deployment."
+  long: |-
+    Because you may need to change the variable for Kubernetes, this label
+    forces the value to another. It is also particullary helpful to use a template 
+    value instead. For example, you could bind the value to a service name 
+    with Helm attributes:
+    {{ "{{ tpl .Release.Name . }}" }}.
+
+    If you use __APP__ in the value, it will be replaced by the Chart name.
+  example: |-
+    env:
+      DB_HOST: database
+      RUNNING: docker
+      OTHER: value
+    labels:
+      {{ .KatenaryPrefix }}/map-env: |-
+        RUNNING: kubernetes
+        DB_HOST: '{{ "{{ include \"__APP__.fullname\" . }}" }}-database'
+  type: "map[string]string"
+
+"health-check":
+  short: "Health check to be added to the deployment."
+  long: "Health check to be added to the deployment."
+  example: |-
+    labels:
+      {{ .KatenaryPrefix }}/health-check: |-
+        livenessProbe:
+          httpGet:
+            path: /health
+            port: 8080
+  type: "object"
+
+"same-pod":
+  short: "Move the same-pod deployment to the target deployment."
+  long: |-
+    This will make the service to be included in another service pod. Some services 
+    must work together in the same pod, like a sidecar or a proxy or nginx + php-fpm.
+
+    Note that volume and VolumeMount are copied from the source to the target 
+    deployment.
+  example: |-
+    web:
+      image: nginx:1.19
+
+    php:
+      image: php:7.4-fpm
+      labels:
+        {{ .KatenaryPrefix }}/same-pod: web
+  type: "string"
+
+"description":
+  short: "Description of the service"
+  long: |-
+    This replaces the default comment in values.yaml file to the given description. 
+    It is useful to document the service and configuration.
+
+    The value can be set with a documentation in multiline format.
+  example: |-
+    labels:
+      {{ .KatenaryPrefix }}/description: |-
+        This is a description of the service.
+        It can be multiline.
+  type: "string"
+
+"ignore":
+  short: "Ignore the service"
+  long: "Ingoring a service to not be exported in helm chart."
+  example: "labels:\n  {{ .KatenaryPrefix }}/ignore: \"true\""
+  type: "bool"
+
+"dependencies":
+  short: "Add Helm dependencies to the service."
+  long: |-
+    Set the service to be, actually, a Helm dependency. This means that the 
+    service will not be exported as template. The dependencies are added to 
+    the Chart.yaml file and the values are added to the values.yaml file.
+
+    It's a list of objects with the following attributes:
+
+    - name: the name of the dependency
+    - repository: the repository of the dependency
+    - alias: the name of the dependency in values.yaml (optional)
+    - values: the values to be set in values.yaml (optional)
+
+    !!! Info
+        Katenary doesn't update the helm depenedencies by default.
+        
+        Use `--helm-update` (or `-u`) flag to update the dependencies.
+        
+        example: <code>katenary convert -u</code>
+
+    By setting an alias, it is possible to change the name of the dependency 
+    in values.yaml.
+  example: |-
+    labels:
+      {{ .KatenaryPrefix }}/dependencies: |-
+        - name: mariadb
+          repository: oci://registry-1.docker.io/bitnamicharts
+
+          ## optional, it changes the name of the section in values.yaml
+          # alias: mydatabase
+
+          ## optional, it adds the values to values.yaml
+          values:
+            auth:
+              database: mydatabasename
+              username: myuser
+              password: the secret password
+  type: "[]object"
+
+"configmap-files":
+  short: "Inject files as Configmap."
+  long: |-
+    It makes a file or directory to be converted to one or more ConfigMaps 
+    and mounted in the pod. The file or directory is relative to the 
+    service directory.
+
+    If it is a directory, all files inside it are added to the ConfigMap.
+
+    If the directory as subdirectories, so one configmap per subpath are created.
+
+    !!! Warning
+        It is not intended to be used to store an entire project in configmaps.
+        It is intended to be used to store configuration files that are not managed 
+        by the application, like nginx configuration files. Keep in mind that your
+        project sources should be stored in an application image or in a storage.
+  example: |-
+    volumes
+      - ./conf.d:/etc/nginx/conf.d
+    labels:
+      {{ .KatenaryPrefix }}/configmap-files: |-
+        - ./conf.d
+  type: "[]string"
+
+"cronjob":
+  short: "Create a cronjob from the service."
+  long: |-
+    This adds a cronjob to the chart.
+
+    The label value is a YAML object with the following attributes:
+    - command: the command to be executed 
+    - schedule: the cron schedule (cron format or @every where "every" is a 
+      duration like 1h30m, daily, hourly...)
+    - rbac: false (optionnal), if true, it will create a role, a rolebinding and
+      a serviceaccount to make your cronjob able to connect the Kubernetes API
+  example: |-
+    labels:
+        {{ .KatenaryPrefix }}/cronjob: |-
+            command: echo "hello world"
+            schedule: "* */1 * * *" # or @hourly for example
+  type: "object"
+
+"env-from":
+  short: "Add environment variables from another service."
+  type: "[]string"
+  long: |-
+    It adds environment variables from another service to the current service.
+  example: |-
+    service1:
+      image: nginx:1.19
+      environment:
+          FOO: bar
+
+    service2:
+      image: php:7.4-fpm
+      labels:
+        # get the congigMap from service1 where FOO is 
+        # defined inside this service too
+        {{ .KatenaryPrefix }}/env-from: |-
+            - myservice1
+
+"exchange-volumes":
+  short: Add exchange volumes (empty directory on the node) to share data
+  type: "[]object"
+  long: |-
+    This label allows sharing data between containres. The volume is created in 
+    the node and mounted in the pod. It is useful to share data between containers
+    in a "same pod" logic. For example to let PHP-FPM and Nginx share the same direcotory.
+
+    This will create:
+
+    - an `emptyDir` volume in the deployment
+    - a `voumeMount` in the pod for **each container**
+    - a `initContainer` for each definition
+
+    Fields:
+      - name: the name of the volume (manadatory)
+      - mountPath: the path where the volume is mounted in the pod (optional, default is `/opt`)
+      - init: a command to run to initialize the volume with data (optional)
+
+    !!! Warning
+        This is highly experimental. This is mainly useful when using the "same-pod" label.
+
+  example: |-
+    nginx:
+      # ...
+      labels;
+        {{ .KatenaryPrefix }}/exchange-volumes: |-
+          - name: php-fpm
+            mountPath: /var/www/html
+    php:
+      # ...
+      labels:
+        {{ .KatenaryPrefix }}/exchange-volumes: |-
+          - name: php-fpm
+            mountPath: /opt
+            init: cp -ra /var/www/html/* /opt
+
+"values-from":
+  short: "Add values from another service."
+  long: |-
+    This label allows adding values from another service to the current service.
+    It avoid duplicating values, environment or secrets that should be the same.
+
+    The key is the value to be added, and the value is the "key" to fetch in the
+    form `service_name.environment_name`.
+
+  type: "map[string]string"
+  example: |-
+    database:
+      image: mariadb:10.5
+      environment:
+        MARIADB_USER: myuser
+        MARIADB_PASSWORD: mypassword
+      labels:
+        # we can declare secrets
+        {{ .KatenaryPrefix }}/secrets: |-
+          - MARIADB_PASSWORD
+    php:
+      image: php:7.4-fpm
+      environment:
+        # it's duplicated in docker / podman
+        DB_USER: myuser
+        DB_PASSWORD: mypassword
+      labels:
+        # removes the duplicated, use the configMap and secrets from "database"
+        {{ .KatenaryPrefix }}/values-from: |-
