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
