sorry for the lack of carrage return ^^

It work for me , but not sure if it works by default sudo dnf install python-docker docker sudo systemctl enable docker && sudo systemctl start docker sudo molecule init role -r lol and then sudo molecule test TASK [Destroy molecule instance(s)] ******** fatal: [localhost]: FAILED! => {"msg": "An unhandled exception occurred while templating '{{ lookup('file', molecule_file) | molecule_from_yaml }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: template error while templating string: no filter named 'molecule_from_yaml'. String: {{ lookup('file', molecule_file) | molecule_from_yaml }}"} Not sure if it's normal it dont install docker and python-docker by default and fail with a default config ?

With: sudo dnf --enablerepo=updates-testing install python-molecule

molecule init role -r rpm --> Initializing new role rpm...

Not sure if fonctional :/ i got this cookiecutter.exceptions.RepositoryNotFound: A valid repository for "/usr/lib/python3.6/site-packages/molecule/command/init/../../cookiecutter/role" could not be found in the following locations: /usr/lib/python3.6/site-packages/molecule/command/init/../../cookiecutter/role /usr/lib/python3.6/site-packages/molecule/command/init/../../cookiecutter/role

Ok for me and necessary for running in fedora 28 because of python 3.6 because of bug Fedora@1575821

Works fine for me
