Description Dirk Schnick

We now had several tickets, where we need to help customers in trouble. The reason was, that the network interface used an IP of the docker network. All customers I worked with told me, that this IP was set on installation.

So from my point of view we should check if the networks we use for docker are used on any network interface during installation and if we should set another network for docker.
Alternative we could ask for the docker networks during installation, in this case the customer is aware about these networks (all customers where not aware of them!)
Another alternative would be a diagnostic check but from my point of view is that the worst way to prevent such situations.

btw. this problem is hard to debug as the problems are coming in several flavors.
