Allow stdin for kube play

[mcexit]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description

podman_play module only allows file input.

Describe the results you received: podman_play only allows file input using kube_file which is required.

Describe the results you expected: podman_play module should allow for variable input, not just file. This allows the utilization of something like kubernetes.core.kustomize lookup

@mcexit can you please post an example of what you would like to have? What can be in stdin?

[mcexit]

An example is whatever manifest you want to pass to podman_play (akin to kustomize build <path> | podman play kube -. This could be created with the kubernetes.core.kustomize Ansible lookup module:

An example is whatever manifest you want to pass to podman_play (akin to kustomize build <path> | podman play kube -. This could be created with the kubernetes.core.kustomize Ansible lookup module:

I'd like to understand how would look ansible task with it. Can you please provide a desired example? Like registering stdout from kustomize or something else?

[mcexit]

That is one possibility, but there is a kustomize lookup module already in ansible:

https://docs.ansible.com/ansible/latest/collections/kubernetes/core/kustomize_lookup.html

So it would look like:

- name: Play kube file
  containers.podman.podman_play:
    stdin: "{{ lookup('kubernetes.core.kustomize', dir='/path/to/kustomization') }}"

You could even use "{{ lookup('template', 'somefile.yaml') }}"
