Molecule won't start Docker container - fatal: [centos8]: UNREACHABLE! => {"changed": false, "msg": "Authentication or permission failure ...

When run molecule test, I got the following error: fatal: [centos8]: UNREACHABLE! => {“changed”: false, “msg”: “Authentication or permission failure. In some cases, you may have been able to authenticate and did not have permissions on the target directory. Consider changing the remote tmp path in ansible.cfg to a path rooted in "/tmp". Failed command was: ( umask 77 && mkdir -p "echo ~/.ansible/tmp/ansible-tmp-1602159340.7644343-138649041382011" && echo ansible-tmp-1602159340.7644343-138649041382011="` echo ~/.ansible/tmp/ansible-tmp-1602159340 exited with result 1”, “unreachable”: true}

After this failure, “docker ps -a” return nothing, which means no docker containers were started.

My platform is wsl 2 on Window 10 coomand “docker run hello-world” indicates the docker is working properly

the versions of pip and python are: Python 3.8.5 and pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8) the molecule.yml:

dependency: name: galaxy driver: name: docker platforms:

• name: centos7 image: geerlingguy/docker-centos7-ansible provisioner: name: ansible verifier: name: ansible

Hi, i’m getting the exact same error message using molecule version 2.20.2.

If I run, molecule converge, molecule verify, molecule destroy separately, it works fine. I only seem to get the UNREACHABLE error when I use the molecule test command. I have nothing within my ~/.cache/molecule directory either.

@shanxijie Glad to hear you were able to figure it out!
