This is a good start and there are some things we could improve.

I recommend merging #733 first, then rebasing this PR onto main, so that the linter will run on this PR.

I understand we've used apt_key for a while, but as the apt_key docs explain, the latest Debian/Ubuntu will no longer support this.

It's ok for today, but in the future, prepare to use the alternative example in the apt_repository docs (the get_url module plus the signed-by setting).

We should do this the new way, and we should also work on fixing all the rest of the apt-key invocations. One of the Debs already requires it and I'm not sure but I think newer Ubuntu may as well.

I updated the key import task to ansible.builtin.get_url and tested it on apt/rpm machines.

I don't think we should put variables into main.yml unless we'll set different values for different hosts. You can always template those settings out later and move them to main.yml later in future pull requests.

Adam and I chatted about this PR.

  • These variables exist because Adam sets them with extra_vars when running the playbook interactively on his computer.
  • We discussed the possibility of tracking those particular non-default choices in host_vars or group_vars instead so that we can understand how and why Adam made those choices to alter the values from the defaults.

@akraitman have you resolved all of Ken's earlier issues?

Yes, I removed the if statement from grafana-agent.yaml.j2 and removed the "agent_metrics" variable from defaults/main.yml
