Docker version used is on a WSL2 with a Docker Desktop v.4.19.0 and a Docker Engine version 24.0.2.

Molecule installation method (one of):

pip using a virtualenv

Ansible installation method (one of):

pip using a virtualenv

Detail any linters or test runners used:

Desired Behavior

Getting the Docker image build by Ansible using the molecule test or molecule create commands with Docker containers up and running.

Actual Behaviour

For some weird reasons, the molecule create or molecule test command failed at the Ansible task "Build an Ansible compatible image (new)" with the following error message :

The error was: ansible_collections.community.docker.plugins.module_utils._api.credentials.errors.StoreError: Unexpected OS error "Exec format error", errno=8

The error seems to happend in the following playbook file : $INSTALLATION_MOLECULE_PATH_USING_PIP/lib/python3.10/site-packages/molecule_plugins/docker/playbooks/create.yml

The complete error even with the verbose debug -vvvv is the following :

Before upgrading the Molecule and the Ansible version it was working perfectly. Maybe there is an issue with a Python conflict packages such as requests and docker.

pip freeze
ansible==7.6.0
ansible-compat==3.0.2
ansible-core==2.14.6
ansible-lint==6.16.2

PyYAML==6.0
requests==2.31.0

I have no idea what's going on and why this is happening and I'll appreciate some help on the subject. :)

Kind regards,
Tom

You're probably running into microsoft/WSL#8952 when it tries to use a credentials helper since the error is: Exec format error: '/usr/bin/docker-credential-desktop.exe'. Try the fix mentioned in the issue I linked and see if it will work.
