Docker Bridge

Does setup bridge under network settings need to be set to yes for docker and containers to work

No. Network interface bridging and Docker container bridging are two different things, and one isn't really dependent on the other.

 

Network interface bridging causes your unraid box to perform Layer 2 Ethernet packet forwarding between the two bridged interfaces; you could conceptually think of it as turning your NAS into a simple unmanaged Ethernet switch.

 

Docker container bridging has to do with the way ports are mapped and exposed between a container and the host system. If you configure a container for "host", then all ports used by any services in the container are exposed to the host. If you configure it for "bridge", then only the ports explicitly mapped in your configuration are exposed to the host. Honestly, I think the naming conventions here are a bit misleading; "host" and "bridge" mean something different in the context of virtual machines, and I've spent a lot more time with ESXi than I have with Docker
