Installing molecule[docker] does not bring all dependencies with Ansible-Core.

[rjeffman]

Issue Type

• Bug report

Molecule and Ansible details

• ansible-core-2.11.4
• molecule-3.4.0
• molecule_docker-0.2.4

Molecule installation method (one of):

• pip

Ansible installation method (one of):

• pip

Desired Behavior

When installing molecule[docker] through pip, along with Ansible-core 2.11, all required dependencies should also be installed.

Actual Behaviour

It seems that docker_login is used by molecule, and is not being installed, as Ansible-core does not contain community modules.

ERROR! couldn't resolve module/action 'docker_login'. This often indicates a misspelling, missing collection, or incorrect module path.

The error appears to be in '/opt/hostedtoolcache/Python/3.6.14/x64/lib/python3.6/site-packages/molecule_docker/playbooks/create.yml': line 11, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

This issue should be resolved by ansible-community/molecule-docker#77 and #3192

IIRC, Molecule with those changes has been already released, but we still need to make a docker driver release, so I am leaving this open until that happens.

@ssbarnea Are there any plans on releasing a new version of molecule docker driver?

[ssbarnea]

molecule-docker 1.0.2 was released 5 days ago, closing. For bugs related to drivers please raise tickets with driver repositories instead of molecule itself.
