Use ubi8/ruby-27

[yselkowitz]

This is necessary for the build tests on other architectures, as the
centos S2I images are x86_64 only.

I think there is enough direct usage in @yselkowitz 's accompanying openshift/origin PR to get sufficient validation @bparees

There are some direct references to the ubi8 image like https://github.com/openshift/origin/pull/26072/files#diff-2743afa0b07bbf4dd58d08076cb9e16b645182ba82e83f9cc8a5575c29bf7db2R1

plus there are a lot spots where he has switched imagestreamtag refs from ruby:2.7 to ruby:2.7-ubi8 .... that moves things to registry.redhat.io/ubi8/ruby-27:latest

I would be very surprised if registry.redhat.io/ubi8/ruby-27:latest worked and registry.access.redhat.com/ubi8/ruby-27:latest did not.

So assuming openshift/origin#26072 looks OK in the morning I say let's move forward with this.

But of course I'm fine waiting on feedback from @adambkaplan and @soltysh as well if they have any.

thanks @yselkowitz / @bparees

Getting the tests and this coordinated will take a bit more work.

Similarly to what Gabe wrote earlier, from oc pov, most of the tests don't care about contents, as long as the image is present.

@yselkowitz are you still working on this? anything you need from us here or on openshift/origin#26072 ?

[yselkowitz]

I am working on this (among many other things), but it looks like the origin PR can't be as self-isolated as I hoped, so it's going to take a bit longer to get a reviewable set of commits there.

[openshift-ci]

@yselkowitz: PR needs rebase.

What is needed to get this in now?

[bparees]

@yselkowitz it's a manual merge process (i can do it) so if all the vetting has been done that these changes are compatible w/ origin testing, i can do it. let me know.

[gabemontero]

also needs to rebase per the git bot ...i.e. has needs-rebase label

[yselkowitz]

Just tested a manual Dockerfile build of this with ruby-27-centos7 but w/o the explicit scl enable commands, and the container builds and runs like that, so it seems the container-entrypoint is doing its job, and this should be backwards compatible.

I rebased almost three weeks ago and there have been no new changes since; is the bot sleeping here?
