Add Candlepin pipeline to run puppet-candlepin tests

[ehelms]

Starter test pipeline, this will require some changes to puppet-candlepin to allow configuring the repository to test. My goal is to provide this for theforeman/foreman-infra#1937 (comment)

@ekohl How would you make https://github.com/theforeman/puppet-candlepin/blob/master/spec/setup_acceptance_node.pp#L20 configurable for running the beaker tests dynamically? I can imagine wanting to set:

• Candlepin version for a known repository location
• A different repository URL for testing against different locations (e.g. stage, prod)

[ekohl]

I'm (mostly) happy with how puppet-pulpcore does it.

• pulpcore::repo has a parameter
• That version is set in setup_acceptance_node.pp using environment variables
• These versions are set in the matrix build

I'm unhappy with the last part: gha-puppet should have a way to do this without having to copy the whole workflow.

My plan to solve that was to first get voxpupuli/puppet_metadata#35 done. That makes it possible to solve this TODO. Then we can consider ways to input those versions to CI.

@ekohl Does this look good for a start? theforeman/puppet-candlepin#244

@ehelms I moved a few things around, to make it even more re-useable, and overall I like it :)

[ehelms]

This now relies on theforeman/puppet-candlepin#252 and relies upon two additional variables:

ansible-playbook pipelines/candlepin.yml -e pipeline_os=centos8-stream -e pipeline_version=nightly -e pipeline_beaker_os=centos9 -e pipeline_beaker_os_version=9

[evgeni]

Can't we deduct the additional variables from the pipeline_os? We have (today) no good way for passing in additional vars via Jenkins. We could have them in some vars file… but it feels odd given that IMHO all the data should already be present.

[evgeni]

technically, given this runs on the vagrant box, this could be

Suggested change

	BEAKER_FACTER_CANDLEPIN_BASEURL: "https://stagingyum.theforeman.org/candlepin/{{ pipeline_version }}/el{{ pipeline_beaker_os_version }}/x86_64"
	BEAKER_FACTER_CANDLEPIN_BASEURL: "https://stagingyum.theforeman.org/candlepin/{{ pipeline_version }}/el{{ ansible_distribution_major_version }}/x86_64"

[ehelms]

That won't work for testing EL8 and EL9 when the host itself is only EL8. That is why I felt these additional variables had to be introduced.

[evgeni]

Agreed. I was working under the assumption we're keeping the current mode where we spin up a VM that matches the target OS.

I think I'm missing some bigger piece how this should be executed by automation.

[ehelms]

Fair, while not efficient, that is how this workflow works and we could keep that connection and assumption.
