Proposal: Enable s390x (IBM Z) Support in GitHub Actions CI

[niyamsw]

Hello Team,

We are interested in enabling s390x support for Apache CloudStack GitHub Actions CI workflows.

We now have hosted GitHub Actions runners available for IBM Z (s390x), and we are gradually onboarding open source communities to make use of this infrastructure as we continue expanding capacity. We believe this could help Apache CloudStack broaden its architecture coverage and strengthen cross-platform validation.

As part of our initial validation, we have executed the current Apache CloudStack GitHub Actions workflows on private s390x runners, and all workflows are passing successfully. This indicates that the project is already in good shape for s390x enablement with minimal additional effort.

We would be happy to engage with the Apache CloudStack community to explore whether this solution would be beneficial and how we can assist with the enablement process.

An onboarding document is available here:
https://github.com/IBM/actionspz/blob/main/docs/FAQ.md

If the community is interested, we would be glad to provide the necessary support to help get things started.

Please let me know your thoughts. Thanks!

Regards
Niyam Siwach

sounds good @niyamsw , Is your plan

• to add a workflow or
• to extend the test matrix workflow (ci.yml) to utilise extra runners and run all the tests on s390 in parallel?

Hi @DaanHoogland,

We plan to add separate s390x workflow files for Build, UI, Docker, and CI, instead of adding to the current ci.yml matrix.

This doesn't change any of the current workflows and lets us stabilize s390x. We can think about adding it to the main test matrix once it is stable.

Glad to go along with what the community prefers.

@niyamsw , in that case I think it would make sense to copy the ci.yml and adapt it for use with your runners.
