Molecule will not run after editing converge.yml

[gpettey-ercot]

Prerequisites

• This was not already reported in the past (duplicate check)
• It does reproduce it with code from main branch (latest unreleased version)
• I include a minimal example for reproducing the bug
• The bug is not trivial, as for those a direct pull-request is preferred
• Running pip check does not report any conflicts
• I was able to reproduce the issue on a different machine
• The issue is not specific to any driver other than 'default' one

Environment

After following basic install/setup in collection/extensions, molecule will not run after I have edited converge.yml to include my role.

-    - name: Replace this task with one that validates your content
-      ansible.builtin.debug:
-        msg: "This is the effective test"
+    - name: include certs role
+      ansible.builtin.include_role:
+        name: certs

What happened

With the default "sample" it will run succesfully:

On the examples page, there are a couple of files suggested to use podman, but says also This example is using Ansible playbooks and it does not need any molecule plugins to run. I have installed molecule-plugins[podman], therefore I should not need that, correct?

Reproducing example

A simple modification to the converge.yaml file produced by `molecule init scenario`, to include ANY role.

---
- name: Converge
  hosts: all
  gather_facts: false
  tasks:
    - name: include certs role
      ansible.builtin.include_role:
        name: certs

it smells like a duplicate of #4372 . I've merged yesterday a fix for that in the plugins repo. I hope to make a new release very soon.

It is not. I applied the changes from ansible-community/molecule-plugins#294 to the podman driver, and I still see same output minus the error and trace about run_command. Evem after updating molecule-plugins to the new release instead of manually fixing it, the same. I updated the snippets in the top post to remove that error output.

[apatard]

@gpettey-ercot oh ok. Now that I'm looking at the new output, it's failing to connect to the test instance and the create.yml playbook doesn't seem to do a lot of things.

• Which plugin are you using ? [ is your molecule.yml available somewhere ? ]
• Did you check the create/destroy playbooks ? If you're using a plugin from molecule-plugins, you may have to remove or overwrite the ones in the molecule project directory

[gpettey-ercot]

That those files need to be deleted to use the ones defined in molecule-plugins[podman] should be documented and/or highlighted if it is already documented :) It works now that I know to remove them. I'd also suggest adding an option to molecule init scenario to not generate those two files.
