Improve flexibility

Change content and motivation

Some apps require larger local disk space or the use of a converged storage solution, this can easiest be completed by adding storage to the worker nodes.

Some clusters has external ingress controllers available, add the option to not deploy traefik.

There is a need to talk to the kublets when monitoring the kubernetes back plane.
