SUSE CaaS Platform 3 (and 2 and 1) are based on MicroOS, a specialized version of SLES with a read-only file system, making standard management tools incompatible. The forthcoming version 4 is installed as a SLES 15 SP1 add-on, making it compatible with SUSE Manager, YaST, autoyast, etc. - at least for the OS level. (CaaS Platform 4 itself is delivered as a small installation pattern which then installs the rest of the product as containers from the SUSE Registry.)

If you want to check it out, it is now in mid-Beta, and you can get it at https://www.suse.com/betaprogram/caasp-beta/

Thanks!
