The build of the image fails due to line

&& dnf config-manager --add-repo https://ci.mariadb.org/galera/mariadb-4.x-latest-gal-${ARCH}-${ID}${VERSION_ID}.repo \

that evaluates to https://ci.mariadb.org/galera/mariadb-4.x-latest-gal-aarch64-openeuler-24.repo and is not available yet.

Hi Martin!

Thank you for your contribution.
I think we can skip Galera installation for now. Once we merge #541 we will have an easy way to skip Galera related lines in our CI. I'll let @grooverdan confirm.

For our CI to build an image for openEuler it's necessary to add a block of code here:

buildbot/.github/workflows/build-centos-based.yml

Line 26 in 3cd229e

- image: almalinux:8

but I don't know if this is planned yet or we are just preparing the underlying dockerfile.

The difference between centos and centos-pip yml workflows is the installation of twisted & buildbot-worker. It depends on the availability of these 2 packages in the distribution default repository. https://github.com/MariaDB/buildbot/blob/dev/ci_build_images/pip.Dockerfile
