Painless Docker - 2nd Edition

docker network create my_bridge_network

# This is equivalent to:
# docker network create --driver bridge my_bridge_network
# since bridge is the default driver

# Create two containers busybox1 and busybox2 on the user-defined bridge network
docker run -it -d --name busybox1 \
    --network my_bridge_network busybox
docker run -it -d --name busybox2 \
    --network my_bridge_network busybox

# Ping using container names should succeed now
docker exec -it busybox1 ping -c1 busybox2
docker exec -it busybox2 ping -c1 busybox1
