Yes working on incorporating the review comments given by Nick.

I think I need to add the same changes I did on plugin registry there so it will include less changes

[aditijadhav38]

@benoitf Could you please tell me by when you will be adding these changes, so accordingly we will update files

[benoitf]

I will work on it now 👍

@nickboldt @benoitf Just curious to check if we can use registry.fedoraproject.org/fedora-minimal docker image as base image in RHEL dockerfile. We are anyways using Fedora repositories so why not use its base image itself? The fedora-minimal image support multi-arch.

I tried using it to build che-plugin-registry docker image and I am able to do so on s390x arch. I can share the code changes if you want.

[nickboldt]

I will let Florent address that one. I'm happy to use Fedora (bearing in mind we can't use it downstream), but UBI8 is better since that's what we'll be using in Brew to build CRW for OCP/Z.

[benoitf]

Well, if the rhel.Dockerfile is not used downstream either we remove it or we stick to ubi8.

[nickboldt]

Much simpler solution. +1 from me.

[nickboldt]

@ericwill or @benoitf any concerns with this latest approach?

Seems easy enough and won't be too painful to port to downstream (can't use Fedora but can use EPEL and unreleased RHEL bits).

Also relatively confident this will work for ppc64le support instead of eclipse-che/che-plugin-registry#462

[benoitf]

I'm fine (BTW AFAIK we don't use rhel.Dockerfile upstream)

[ericwill]

LGTM, only thing of note is that Fedora 30 will be EOL in 6 months.
