Description Sven Göricke

2019-12-11 13:41:22 CET

+++ This bug was initially created as a clone of Bug #40515 +++

See Ticket#2016012621000471

Recently the issue described in #40515 has popped up again at customer site.
If a customer has the network 172.17.0.0/16 it will be in conflict with the default docker bridge with 172.17.42.1/16. The network traffic won't work anymore.

To circumvent the issue we switched to a second console when UCS installation assistant started (just after reboot from base installation) and changed the following two UCR Variables accordingly:

1) docker/daemon/default/opts/bip
2) appcenter/docker/compose/network

Maybe it is also an option to add the docker-network as an configuration item during UCS installation assistant?

I guess this would have to be added to the system setup, I change the Bug component accordingly.
