To be able to create a release of a helm chart we will need to first, create the package and then generate / update the index.yaml for being able to serve it as a repo using any webserver of our choice
To be able to release a chart we can just create a tar with the templates ignoring the files on the .helmignore file, or let helm do it for us using helm package*. It's usage it's as straigforward as this:
$ helm package . Successfully packaged chart and saved it to: /home/pet2cattle/git/ampa/helm-ampa/ampa-1.0.1.tgz
Once we have the file, to be able to create a helm repository from with helm can retrieve charts we will have to create a index.yaml. Again, helm can also do it for us using helm repo index:
$ helm repo index .
This generates a index file as follows. In this example we only have one release available:
apiVersion: v1 entries: ampa: - apiVersion: v2 appVersion: "3.56" created: "2021-04-17T12:57:53.972445585+02:00" description: AMPA digest: b4f5423ca79ccb38d0ae12be5f6cddedfd57cae97fb2f3a5d57fdbf6907bd7bd name: ampa type: application urls: - ampa-1.0.3.tgz version: 1.0.3 generated: "2021-04-17T12:57:53.971477552+02:00"
Once we have the tarball and the index.yaml, we just need to serve them on any URL (for example using nginx) to be able to use them as a repo
