Unable to test via molecule own role with a dependency to openshift-applier

[matihost]

If own role uses molecule and uses openshift-applier dependency to - the "openshift-applier" role is run with empty results.

The reason is the openshift-applier git repository equals to the name of the role "openshift-applier" So even adding :

provisioner:
  name: ansible
  log: True
  env:
    ANSIBLE_ROLES_PATH: /tmp/molecule/role-under-test/default/roles/openshift-applier/roles

does not help because molecule append ANSIBLE_ROLES_PATH to ansible rolepath at the end. Since /tmp/molecule/role-under-test/default/roles is earlier on the role path, Ansiblefinds /tmp/molecule/role-under-test/default/roles/ansible-applier directory - which is not valid Ansible role - and it assumes role is empty.

So when Ansible looks for "openshift-applier" role, it finds it earielir (and find the git repository name) and assumes empty.

The problem could be solved in various ways:

• openshift-applier repo to follow Ansible role directory structure from the top git repo level
• moving to gilt in molecule but an attempt to download only src: roles/openshift-applier ends with "[Errno 40] Too many levels of symbolic links: '/home/user/.gilt/clone/.openshift-applier/roles/openshift-applier/tests/roles/openshift-applier/tests/roles/openshift-applier/tests/roles/openshift-applier/tests/roles/openshift-appbblablabla'")] - it seems gilt doesn't like symbolic links.
• ansible galaxy to allow importing subdirectories of git repos
• molecule - to change mind with https://github.com/ansible/molecule/issues/1273 - to allow overriding role path or to allows to inject own directories to role path before core rolepath list

Workaround is:

• disable molecule dependency step
• run galaxy or gogitit or git submodules to download openshitt-applier
• add 'openshift-applier/roles/' to molecule ANSIBLE_ROLES_PATH env

Sample makefile to automate stuff:

test: clean get-dependencies ## Test own role
    molecule test

get-dependencies: clean ## download galaxy dependencies
    ansible-galaxy install -r requirements.yml -p galaxy -f

clean:
    -rm -rf galaxy

where molecule.yml is the following:

# cannot use with Ansible role where git role is in subdirectory, and role name equals git repo (for example https://github.com/redhat-cop/openshift-applier.git)

#  name: galaxy
