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
