So confused - tox for ansible-lint only (solved)

I can’t wrap my head around how to use tox to just run ansible-lint against a collection that doesn’t have any plugins to build and test. It seems like it should be simple but the I can’t seem to get the right mix of configuration files to make it work.

At this point you may be wondering why not just run ansible-lint by itself. In this situation I would like to take advantage of the tox environment setup to set the python, ansible and ansible-lint versions so that it aligns with the pipeline testing.

Eventually I’d like to keep adding to this for additional linters and molecule, but step one is just getting it to run ansible-lint.

--------- Fast forward a few hours ------

I’m glad I waited to post this because I have something working now. Sharing so hopefully someone doesn’t have to bang their head against this like I did.

Created this tox.ini file

; tox.ini
[tox]
env_list =
    lint-roles
    lint-playbooks
no_package = true

[testenv]
commands_pre =
    ansible-galaxy collection install .
deps =
    distlib  # Needed for collection build using manifest method
    ansible-core
    ansible-lint

[testenv:lint-roles]
commands = 
    ansible-lint roles/

[testenv:lint-playbooks]
commands = 
    ansible-lint playbooks/

Running tox -av returns the following

bash-5.2$ tox -av
default environments:
lint-roles     -> [no description]
lint-playbooks -> [no description]

Running tox runs ansible-lint against the roles and playbooks directory as expected.

The part that wasn’t obvious was this flag, “no_package = true”. Once that is set it will stop trying to build non-existent python packages and work with role only collections.
