I didn't really mean to support building RHEL packages from the source. Indeed even for Ubuntu we'll stop for 20 and 22 (we're shipping .deb files soon).

I mean there's no real point to when you have RPMs available. Is there a reason why you're building from source instead of pulling an RPM (or a nightly RPM?).

[xpillons]

Building from source will allows us to add our private ood_core project

[johrstrom]

Do you have somewhere where you can host an RPM, (nexus or similar, ansible may just respond to a local file too).

I'd suggest building an RPM with your updates and stashing that somewhere.

[xpillons]

yes that was my first attempt. It's not really clear which branch to use and the version appears to be 2.0.0 and not the latest 2.0.x one. This is the github repo and workflow doing it https://github.com/xpillons/ondemand/blob/azhop/release_2.0/.github/workflows/build_rpms.yml

Yea we're changing the packaging a bit from 2.1 to 2.0. So you have to be careful when looking at both of them, because packaging has changed significantly from then to now.

If you want something that's strictly 2.0+ you have to keep everything on and from the release_2.0 branch. That means updating it, tagging off of it, and reviewing CI from it (gitlab or github) and not the master (2,1) updates.

Also check for environment variables you can overload. Out Gitlab CI does the RPM building for us (in both master and 2.0). In 2.0 if you specify these you won't check git for the version.

[xpillons]

ok, I didn't wanted to move on 2.1 as there are no official release of it, and I haven't found the file that does the RPM build so I had to reverse engineer it.

The 2.0 branch of packaging is here: https://github.com/OSC/ondemand-packaging/tree/2.0. You use the build.sh which if you want there are Rake tasks in the main ondemand repo to build using that ondemand-packaging repo.

Building from the source is deprecated now. I think the preferred way to do this would be to build a package (RPM in this case) from the fork then use this role to install that package.
