Use compose-go https://github.com/compose-spec/compose-go to make Katenary parsing compose file the official way. Add labels: - `volume-from` (with `same-pod`) to avoid volume repetition - `ignore` to ignore a service - `mapenv` (replaces the `env-to-service`) to map environment to helm variable (as a template string) - `secret-vars` declares variables as secret values More: - Now, environment (as secret vars) are set in values.yaml - Ingress has got annotations in values.yaml - Probes (liveness probe) are improved - fixed code to optimize - many others fixes about path, bad volume check, refactorisation, tests...

{{.LABEL_SECRETVARS | printf "%-33s"}}: secret variables to push on a secret file
|
|
{{.LABEL_ENV_SECRET | printf "%-33s"}}: set the given file names as a secret instead of configmap
|
|
{{.LABEL_MAP_ENV | printf "%-33s"}}: map environment variable to a template string (yaml style)
|
|
{{.LABEL_PORT | printf "%-33s"}}: set the ports to expose as a service (coma separated)
|
|
{{.LABEL_INGRESS | printf "%-33s"}}: set the port to expose in an ingress (coma separated)
|
|
{{.LABEL_VOL_CM | printf "%-33s"}}: specifies that the volumes points on a configmap (coma separated)
|
|
{{.LABEL_SAMEPOD | printf "%-33s"}}: specifies that the pod should be deployed in the same pod than the given service name

|
{{.LABEL_EMPTYDIRS | printf "%-33s"}}: specifies that the given volume names should be "emptyDir" instead of persistentVolumeClaim (coma separated)
|
|
{{.LABEL_HEALTHCHECK | printf "%-33s"}}: specifies that the container should be monitored by a healthcheck, **it overrides the docker-compose healthcheck**.
|
|
{{ printf "%-34s" ""}} You can use these form of label values:
|
|
{{ printf "%-35s" ""}}- "http://[not used address][:port][/path]" to specify an http healthcheck
|
|
{{ printf "%-35s" ""}}- "tcp://[not used address]:port" to specify a tcp healthcheck
|
|
{{ printf "%-35s" ""}}- other string is condidered as a "command" healthcheck
