Docker Networking

Docker Networking

Containers can discover eachother when launched on the same net

Modes are

• bridged
• host
• none

Creating the overlay network

docker network create --driver bridge phenixnet

See the network

docker network ls

Add a container to the network

docker run -d --network=phenixnet --name phenixapp -hostname phenixapp -p 8080 nginx

Ping the container from another one

This will launch a shell on a busybox container, you can ping, curl etc.

docker run -it --rm --network=phenixnet --name phenixapp -hostname phenixclient yauritux/busybox-curl /bin/sh

See the network from the client

curl phenixapp

ping phenixapp

Trash the network

docker network rm
