@ssbarnea as @chrisjsewell I'm wondering about the errors in the pipeline and ask, if the tests are just broken.

[ssbarnea]

I am sure somethings are broken on CI and I hope someone will attempt to fix them. I am unable to do it myself but I will help with review and release. It is not uncommon to have to fix 2-3 other issues before you make you patch mergeable on open-source projects. :p ... not ideal, but the sad reality.

@ssbarnea Issue is that I even can't run tox locally in the master branch with success.

On issue that I spotted easily was the fact that the repo does not contain a docs folder so that the tox tests testenv:docs and testenv:docs-livereload fail. So I removed those test from tox.ini for testing.

@ssbarnea The tox tests pass on my machine (except the ones for python 3.7, 3.8, 3.9 because I don't have those versions installed) but the pipeline is failed with the following error:

So I suspect Ansible isn't correctly installed in the CI pipeline.

Although it should be installed according to the pipeline definition

I will close it as until ansible-collections/community.docker#96 is merged and released we cannot do anything about it.
