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 autmated 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 made to help you to transform "compose" files (docker-compose.yml, podman-compose.yml...) to
complete and production ready Helm Chart.
You'll be able to deploy your project in :material-kubernetes: Kubernetes in a few seconds (of course, more if you need to tweak with labels).
It uses your current file and optionnaly labels to configure the result.
It's an opensource project, under MIT licence, partially developped at Smile. The project source code is hosted on the :fontawesome-brands-github: Katenary GitHub Repository.
Install Katenary
Katenary is developped using the :fontawesome-brands-golang:{ .gopher } Go language. The binary is statically linked, so you can simply download it from the release page of the project in GutHub.
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.
sh <(curl -sSL https://raw.githubusercontent.com/metal3d/katenary/master/install.sh)
!!! Info "Upgrading is integrated to the katenary command"
Katenary propose a upgrade subcommand 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.
git clone https://github.com/metal3d/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.:
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:
replace "bash" by "zsh" if needed
source <(katenary completion bash)
Add this line in you ~/.profile or ~/.bashrc file to have completion at startup.
!!! Edit "Special thanks"
**Katenary is built with:** <br />
> Special thanks to all contributors, testors, and of course packages and tools authors.

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
Docker, Rancher, Helm, Kubernetes, Grafana, Prometheus, and many others are written in Go. Katenary uses Go-Compose
to parse compose files wich is the same library used by Podman-Compose and Docker-Compose. It also uses the
Kubernetes official packages to create Kubernetes objects before to generate the Helm Chart.
**Thanks to everyone who contributes to all these projects.**
**Everything was also possible because of:** <br />

Helm</a> that is the main toppic of Katenary, Kubernetes is easier to use with it.</li>
<li><a href="https://cobra.dev/"><img src="https://cobra.dev/home/logo.png" style="height: 1rem"/> Cobra</a> that
makes command, subcommand and completion possible for Katenary with ease.</li>
