First, install OpenSUSE and rootless docker as explained before. Then for testing:

docker run -e DEBUG_NO_EXIT=1 --rm -ti --cgroupns=host -v /sys/fs/cgroup:/sys/fs/cgroup:rw --name freeipa-server -h ipa.domain.tld -e PASSWORD=Secret123 --sysctl net.ipv6.conf.all.disable_ipv6=0 freeipa/freeipa-server:almalinux-9 -U -r EXAMPLE.TEST --no-ntp --skip-mem-check
