Command

molecule-docker/molecule_docker/playbooks/create.yml

Line 109 in 5ebda29

when: item.override_command | default(true)

Maybe just do a:
when: item.command

There's something off with this task though. Sorry that I don't know how to be more precise.

If you just take the create out and try to run it with a simple variable definition it shouts strange issues since the with_item seems to point to a result dict and not the platform itself.

You would also need to create the filter file... Executing this would give:

TASK [Determine the CMD directives] ********************************************************************************************************************************************************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": 
"The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'name'

The error appears to be in 'docker.yml': line 107, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:
