Helm: Support for Chart.yaml fragments

[manusa]

As a user I would like to provide a fragment for my JKube-generated Chart.yaml file. The contents of this fragment file should be merged with the final Chart.yaml after it has been generated, overriding any matching values.

Similar to #2112

Relates to:

• feat: add support for kustomize api v1beta1 (#4929) fabric8io/kubernetes-client#4930
  Some of the types that were added in scope of this PR could be used for this purpose.
• Enhancement: add support to package my already existing Helm Chart  #865

I couldn't find a direct mapping of Chart.yaml object in Kustomize model.

However, I was able to find a struct in helm repository : Metadata.go

@manusa @rohanKanojia Is it possible to get more information on this? I havent found kustomize in the doc, how do I use it?

Hey Dominik,
The issue had some internal relation with Kustomize during its inception because some of the types are now exposed through the Fabric8 Kubernetes Client model. However, this is completely unrelated now.

This feature allows you to add a chart.helm.yaml file to the src/main/jkube directory. JKube will gather the fields declared in this file and merge them with the ones JKube generates to create a final Chart.yaml file. You can check the following integration test project for more details: https://github.com/eclipse/jkube/tree/ed628ab7274088a66143d9c040bd6c862a531dd4/gradle-plugin/it/src/it/helm-fragment/src/main/jkube
