There seems to be at least one more bug, even with net.proto=IPv6, it is not possibe to create an http connection to localhost:

root@collabora-collabora-online-7c75bcdd98-rn7d5:/# curl -v6 http://localhost:9980

telmich commented 8 months ago

additionally to the net.proto change, the following seems to be required for running it in k8s/ipv6 only:

          securityContext:
            capabilities:
              add:
                - MKNOD
                - SYS_CHROOT

Is it possible to inject a configuration change of net.proto=IPv6 into the docker container at the moment?
