Hi @JBinFla
I have a similar relation to openSUSE as you have. I was very happy running TW on my Desktop, though I am currently running Leap due to some graphic driver issues. Nevertheless, I am acustom to using the openSUSE OS and enjoy having Leap as the underlying OS of my Rockstor Server.
Speaking of Rockstor, I also do use docker on it’s own on Rockstor with docker compose and also use Portainer for diagnostic & debugging. I think it’s great that Rockstor has developed the Rock-ons as it’s easier to learn, but as you are used to manage docker containers “manually”, I would actually advice you to continue doing this.
Because you mentioned cockpit - I have actually installed it on my Rockstor server as well. Though my use case is mainly for managing VMs, I have written my experience down here:
Regarding the TW vs Leap discussion, I know the arguments for both versions, though I defenitely prefer the stability Leap provides for a server. Also the new features and the newer kernel are not as important on a server. Feel free to tinker around with TW, but don’t be afraid of the differences regarding Leap, you won’t notice them for the most part. Updates (command line equivalent zypper up) can be made from the Rockstor Web-UI and that’s also the way I do it most often.
Regards
Simon
