Move prprocessor to shared infrastructure

[ehelms]

The prprocessor project handles a number of tasks for the project and currently runs on @ekohl own infrastructure.

Options to move to:

• OSCI Openshift: https://openshift-console.osci.io

Action Items

• Move to Python 3.7
• Move to one of the shared infrastructure environments
• Make a post to discourse introducing Prprocessor to community again since it's been a while and new developers may not be familiar with it [@ekohl]

I've moved back to Python 3.7 (or really 3.8) compatibility (theforeman/prprocessor@d6eae43). Then I added compatibility with s2i (theforeman/prprocessor@1e6fa69) and documented (theforeman/prprocessor@4ec7fb4).

Now I've switched the URL (at https://github.com/organizations/theforeman/settings/apps/pr-processor) and it's serving from OpenShift. If there is a need to switch back, change the URL to https://prprocessor.ekohl.nl/ which I'll keep running for a while.

At least in theforeman/prprocessor#172 I verified that the webhook delivery works, though that doesn't call back to Redmine. However, it'd surprise me if that's broken.

Now I'll make a post on Discourse to announce the migration. With that I think we should monitor this for a week or so and then consider this resolved.

One thing I couldn't get working was triggering builds after a GitHub push. Probably better to open a new issue for that.

Oh, and running it on HTTPS instead of plain text HTTP. For now I've reverted to my instance.

I've added the following to the openshift route definintion:

  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect

and HTTPS works now.

Thanks for that! I switched the URL back to openshift and monitor it for a bit. Then I can make a Discourse post to announce it.

I've flipped the webhook in https://github.com/theforeman/prprocessor/settings/hooks from using the "github" hook URL in openshift, to the "generic" one, and now push events to the repo trigger new deployments.

(didn't have the motivation to debug why the github specific one didn't work)

[ekohl]

I made an announcement here: https://community.theforeman.org/t/prprocessor-migrated-to-osci/28148

Perhaps the one item (do a more generic introduction) is still open, but it may be better to capture that in a new issue so we can close this one out.

[ekohl]

I've opened #1733 and now consider this as done. Thanks @evgeni for fixing the 2 issues I didn't get around to.

I'll leave the instance on my personal infra running for a while. If there are issues, it should be easy to roll back.
