Ability to run helm pull as a task

[jack1902]

SUMMARY

Basically, i'd like the ability to run ansible to download a bunch of helm charts for use in a separate ansible playbook that wouldn't have any access to the internet.

helm_pull would download all packages locally for use by another ansible-playbook which assumes all charts already exist at a given path.

ISSUE TYPE

• Feature Idea

COMPONENT NAME

kubernetes.core.helm_pull or kubernetes.core.helm_repository could be suitable for this.

ADDITIONAL INFORMATION

Currently, the helm tasks assume that the host running the helm commands has access to the internet but this is not always the case.

- name: Add linkerd chart repo
  kubernetes.core.helm_repository:
    name: linkerd
    repo_url: "https://helm.linkerd.io/stable"

- name: download linkerd chart locally
  kubernetes.core.helm_pull:
    name: linkerd/linkerd2
    # defaults to latest version
    version: VERSION_HERE
    # below would then contain a subdirectory with `linkerd.tgz` chart present or could be dumped out to the `files` directory
    dest: "/tmp/helm_charts"

+1 for this, would get rid of some shell commands in my playbooks
