'pip install molecule-plugins[docker]' does not work as expected

[JustinSenia342]

The molecule docker driver worked just fine for me yesterday, but today it's displaying some unexpected behavior that resulted in the "molecule test" command kicking back an error.

I compared the logs between yesterday and today, and the found a few things which stuck out in the logs:

At the start of the run I now get a:
WARNING docker driver is not installed
(which wasn't there yesterday - when "molecule test" still functioned as expected)

At the end after the stack trace:
AttributeError: module 'molecule.command' has no attribute 'lint'. Did you mean: 'list'?

I'm guessing it's kicking back a missing attribute message is due to an issue with the docker driver install process (can't post the full stack trace though because the error is from a work computer).

I made sure the dependencies were installed, and that didn't seem to be the problem, it looks like the only change may have been a recent update to this plugin - which looks like it may not install the docker driver correctly now for some reason.

If you could look into this, it would be very much appreciated :)

I doubt I'll have time to look at that today, but at least, what I can say:

• 'lint' configuration option of molecule is gone (and the molecule lint command). See the release changelog.
• I've seen in my mails Molecule 5.0 Failing on GitHub Action ansible/molecule#3883 which may be similar to the other warning you're having. Don't know. I'm not sure why it's happening and I dont see any message about schema, otherwise I would have thought about a side effect of Extend schema validation ansible/molecule#3765.

I ran into this today and fixed it by removing any lint configurations I had in my molecule.yml file. As @apatard mentioned, molecule lint is gone from v5.

@JustinSenia342 this is an idea of what I did to fix it:

molecule.yml

provisioner:
   name: ansible
 verifier:
   name: ansible
-lint: |
-  set -e
-  yamllint .
-  ansible-lint .
 scenario:
   test_sequence:
     - dependency
-    - lint
     - destroy
     - syntax
     - create

For GH actions workflow changes:

       - name: Install dependencies
         run: |
-          sudo apt install apt-transport-https ca-certificates curl software-properties-common
+          sudo apt install apt-transport-https ca-certificates curl software-properties-common libssl-dev
           python -m pip install --upgrade pip
-          pip install molecule[docker,lint] ansible yamllint ansible-lint
+          pip install molecule "molecule-plugins[docker]" ansible ansible-core ansible-lint
