Networks

Docker implement DNS server that can resolve to ip adresse of the container

3 main networks drivers

Bridge	none	host
docker run ubuntu	docker run ubuntu --network=none	docker run ubuntu --network=host
Private network inside the docker host use	No networking	It use the docker host network
–port to connect from external	Can not communicate with other containers	no need to specify –port
multiple container can listen on the same port	Isolated network	only one container can listen on the a specific port

Run a container on a specific network

docker run --network <NETWORK_NAME | NETWORK_ID> [...]

Create a new network

Usage: docker network create [OPTIONS] NETWORK

docker network create \
  --driver <DRIVER_NAME> \
  --subnet <SUB_NET>
  <NETWORK_NAME>

# exmaple
docker network create \
  --driver bridge \
  --subnet 180.1.0.0/16
  my-super-network

List all networks

docker network ls
