ppc64le support for quay mirror registry

[Sneha Kanekar]

Hello,

I am currently working adding Power support to Quay Mirror Registry https://github.com/quay/mirror-registry. As a dependency for building Quay Mirror Registry, I need to add Power support to below images:
1) registry.redhat.io/quay/quay-rhel8:v3.7.4 - Currently supported on amd64 only. Docker is located in the official Quay repository https://github.com/quay/quay/blob/master/Dockerfile. I am able to build this image on Power by adding few dependencies in Dockerfile. The image is available in my local Quay repository - quay.io/snehakpersistent/quay:ppc-support-unstable. I'm currently testing the build workflow https://github.com/snehakpersistent/quay/runs/7646675245?check_suite_focus=true. This build workflow with Power support takes around 3hrs as compared to official x86 workflow which takes only 5mins. Root cause for additional time on Power is that wheels for packages gevent and grpcio are not officially available for Power and hence are built in the pipeline. This build time can be reduced by either contributing Power support to gevent and grpcio or by building/supporting wheel file for Power in IBM maintained repository.
2) quay.io/quay/mirror-registry-ee:latest - Unable to pull this image due to authorization issue. Looks like this image is private in quay organization. https://quay.io/organization/quay. Unable to locate Dockerfile for this image.
3) registry.redhat.io/ansible-automation-platform-22/ee-minimal-rhel8:1.0.0-149 - Not supported on Power. Unable to locate Dockerfile for this image.
4) registry.redhat.io/ansible-automation-platform-22/ansible-builder-rhel8:1.1.0-44 - Not supported on Power. Unable to locate Dockerfile for this image.

Can anyone point me to Ansible automation platform source code? Also, I would like to know how I can get access to quay organization and its source code. Any pointers would be really appreciated. Any suggestions are welcome too. Thanks!
