以前、Ansibleを含むDocker Imageに関して、以下を書きました。

ansible-community/toolset

その他、以下を含むDocker image の ansible-community/toolset というものもありました。

ansible
ansible-lint
molecule and most of its plugins
pytest and several of its plugins
yamllint which is used by ansible-lint itself.

実行してみたところ、ansible [core 2.11.1] でした。

moleculeのドライバーは、dockerコンテナ内からの使用と考えるとどの程度使えるか微妙だが、結構入っている。クラウド系は影響は少なそう。
