Desired Behavior

molecule should correctly create/destroy/converge docker containers. It does so if I use my old python venv, but not with the environment created with pipx.

Actual Behaviour

@zeitounator (oh, a climber pic … climber here as well 😉 )

I tried some inject commands and now it seems to work. I will start over to get a clean environment.

pipx list

does not list the injected packages, btw

But it seems OK now, thanks. This makes using topgrade even more useful

Install Molecule could be done with pipx install and pipx inject, e.g.:

pipx install --include-deps flake8
pipx install --include-deps yamllint
pipx install --include-deps ansible
pipx inject --include-apps ansible ansible-lint
pipx inject --include-apps ansible molecule
pipx inject ansible docker
pipx inject ansible openshift
pipx inject ansible python-vagrant
pipx inject ansible netaddr
pipx inject ansible molecule-docker
pipx inject ansible molecule-podman
pipx inject ansible molecule-vagrant
