Known Issues in 2022.11.0

There is a known issue with RHEL8/CentOS Stream 8 when Docker swarm overlay network configuration breaks when the outside network maximum transmission unit (mtu) is smaller than the default value. The mtu is the maximum size of the packet that can be transmitted from a network interface.

Refer to https://github.com/moby/libnetwork/issues/2661 and https://github.com/moby/moby/pull/43197.

When deploying a multinode configuration on RHEL 8/CentOS Stream 8, run the following steps:

Check mtu for docker0 and eth0 using ifconfig | grep mtu.
Set the docker0 mtu value to be equal to eth0 using sudo ifconfig eth0 mtu 1500. Make sure to set the command on all nodes and also after each virtual machine reboot.
