Kubernetes掌舵Java API

Question

Is there any known Java API to use Kubernetes helm (something like the great KubernetesClient from fabric8)? I am trying to initial helm commands from Java but I couldn't find anything that actually works...

Thanks, Nir

Answer 1

I've written microbean-helm . This project:

1. Checks out the .proto files from the Helm project…
2. …generates their gRPC Java bindings…
3. …and adds a couple of utility classes.

The end result is that Tiller, the server-side component of Helm that does all the heavy lifting like chart installation, etc., is addressable and drivable from Java. I am guessing that that is what you really want.

You may follow along at its Github repository .

Answer 2

we've not created a Java API for helm yet on the fabric8 team.

The simplest thing is probably to just use the helm binary for now from your $PATH (or from a docker container if you're using Jenkins Pipeline).

BTW the fabric8 maven plugin supports generating helm charts: https://maven.fabric8.io/#fabric8:helm

You can then apply the helm chart via the command line:

mvn install
helm install target/fabric8/helm/kubernetes/myapp
