Bridge vs Host#

Bridge means you need to use a reverse proxy to map to particular ports. Host means making it available on the same network stack as the host running Docker, so you need to use different ports

If you want to deploy multiple containers connected between them with a private internal network use bridge networking. If you want to deploy a container connected to the same network stack as the host (and access the same networks as the host) use host networking.

Host networking completely disables Docker's network isolation. It means containers see and use exactly the same network interfaces the host has available, without an intermediate NAT layer.
