Docker Networking

Configure Docker Network

We want to use a dedicated subnet / network specifically for containers, so they don't trample over the SERVER and LAN networks. If you are unsure of the name of the network adapter, in this case eth0, just type ipaddr in the terminal to list the network interfaces to locate it. 

docker network create -d macvlan --subnet=192.168.5.0/24 --gateway=192.168.5.1 -o parent=eth0 docker_network

Note

Be sure to replace eth0 with the correct interface name using ip addr in the terminal. e.g. It may appear as something else like ens18, etc. If the interface doesn't exist, Docker will produce an error complaining about it.
