If you want (or in my case have too) test some stuff with SLES and network equipment, you just can add a SLES container to your ContainerLab lab:

name: suse-lab

topology:
    nodes:
       suse:
         image: registry.suse.com/suse/sle15:latest
         kind: linux

One clab deploy later and you can access your SLES container:

root@clab:~/suse-lab# docker exec -ti clab-suse-suse bash
suse:/ # uname -a
Linux suse 6.1.0-40-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.153-1 (2025-09-20) x86_64 x86_64 x86_64 GNU/Linux
