Our Horde docker images have switched over from Tumbleweed to openSUSE LEAP once again.
Recently our container build CI job in github.com broke down unexpectedly. An investigation showed that Tumbleweed’s core libraries, especially libc, were too new for the CI’s build system, based on Ubuntu LTS.
This is the second time we abandoned the Tumbleweed basis for Horde docker containers. OpenSUSE Leap 15.3 uses a relatively old, but well-maintained, set of base libraries. Both Leap and Tumbleweed deliver PHP 7.4 as a basis for Horde. In both systems, we skip the packaged composer version for a static pick which we will update from time to time. We may switch over to packaged composer if we feel confident.
For users and administrators of the image, both Tumbleweed and Leap 15.3 should feel more or less the same. For end users of the delivered horde setup, there should not be any downsides. We will switch back to the Tumbleweed image in a while when we have picked a more recent version of Ubuntu.
