How to execute ansible-lint without downloading dependencies?

[rgl]

I'm running ansible (and ansible-lint) in a container and installing the collections as:

ansible-galaxy collection install \
    -r requirements.yml \
    -p /usr/share/ansible/collections
ansible-galaxy role install \
    -r requirements.yml \
    -p /usr/share/ansible/roles

Then, using a wrapper, execute ansible-lint as:

./ansible-lint.sh --offline --parseable development.yml

But it still fails with:

Why is still trying to call ansible-galaxy collection install when ansible-lint --offline is used? Is there a way for stopping ansible-lint from trying to download the dependencies?

[nre-ableton]

+1 here, the current situation is not very friendly for CI environments, especially because the way that ansible-core calculates role checksums is a bit naive.

[ssbarnea]

The only way to do this is to stop using standalone roles. For collections offline installations is possible but for roles that is not possible and ansible-core will never be updated to add support for such features. I am saying this because I asked about this subject myself several times.

Also starting with v6.10.0 linter should be usable in offline mode.

[nre-ableton]

Unfortunate, but understandable.
