OK, I see. It is really very very powerful. I choose the other solution, running rebase, as I needed to do it anyway. Plus, all this is quite new to me (especially the Kubernetes stuff) and asks a lot of reading and work from myself. I am afraid being lost if I go too deep in the containerize affair.
