Docker Network Drivers

• Docker networking way back was part of docker daemon

• Docker networking is implemented as a different component libnetwork

• Networking in Docker is implemented as Network Drivers. Popular drivers are

  • Bridge
  • Host
  • MACVLAN
  • None
  • Overlay (multi host)

• Refer for Networking Series-1

• Refer for Networking Series – 2 (Multihost)

• Refer Here for official docker network docs

Creating a new bridge network

• Create a new bridge network with range as 10.11.0.0/16 and name as mybridge

docker network create --driver bridge --subnet 10.11.0.0/16 mybridge

docker network ls

docker network inspect mybridge

• Create two container p1 and p2 on the mybridge

docker container run --name p1 --network mybridge -d alpine sleep 1d

docker container run --name p2 --network mybridge -d alpine sleep 1d

• Now test for the connectivity between p1 and p2 using ip and hostnames

docker network inspect mybridge
# make a note of ip addresses
docker exec p1 ping -c 3 10.11.0.3

docker exec p1 ping -c 3 p2

• In the above both containers can connect using names and ip addresss
• Try to add container c1 which is running in bridge network to mybridge network

docker network connect mybridge c1

docker network inspect mybridge


docker exec p1 ping -c 3 c1
