I see that there are only arm64 packages and containers available from the Ceph repo. So I thought I just go ahead and compile the dependency packages myself and build a new container with CentOS7 arm32. Luckily there is a CentOS 7 arm32 container but I still need to compile the packages. After downloading all the src rpms i started building them and now I ended up to compile this package from the SCL repo as it is not available for arm32:
