EXPECTED RESULTS

Uninstall desired chart

ACTUAL RESULTS

Chart stays as pending-install, pending-upgrade or similar, and uninstall gives you and OK result.

We have the same problem, chart in pending-install status will not be uninstalled, and kubernetes.core.helm_info will not show any info about this chart. Example task:

- name: "Check installed helm release"
  kubernetes.core.helm_info:
    release_name: "{{ chart_name }}"
    release_namespace: "{{ chart_namespace }}"
  register: __helm_release

Output for chart in pending-install status: ok: [localhost] => { "__helm_release": { "changed": false, "failed": false } }

I see that in get_release_status function helm list command runs without -a argument https://github.com/ansible-collections/kubernetes.core/blob/bf3fe91a5dfa6f398f74cf242836b0acc28173cf/plugins/modules/helm.py#L357 So it will not see any releases in pending status.

And in chart deletion code I see that it checks current chart status with get_release_status function https://github.com/ansible-collections/kubernetes.core/blob/bf3fe91a5dfa6f398f74cf242836b0acc28173cf/plugins/modules/helm.py#L681-L702

I suppose -a argument should be added to list_command variable to make it work as expected.

issue #377

[LuckySB]

I find PR from 2021 year #204

[LuckySB]

@Akasurde Why did you close the #381 ?

I think to solve the problem https://github.com/ansible-collections/kubernetes.core/pull/204#issuecomment-916193486 it is enough to check the status of the release, and if it is uninstalled, then just do nothing

[julien235]

This function doesn't not seems to work with latest kubernetes.core (2.4.0) or I'm wrong ? My pending-install app was not removed when I specify release_state = absent. Is it possible to reopen this ticket ?
