Returns information about one or more networks. By default, this command renders all results in a JSON object. For example, if you connect two containers to the default bridge network:

$ sudo docker run -itd --name=container1 busybox
f2870c98fd504370fb86e59f32cd0753b1ac9b69b7d80566ffc7192a82b3ed27

$ sudo docker run -itd --name=container2 busybox
bda12f8922785d1f160be70736f26c1e331ab8aaf8ed8d56728508f2e2fd4727

The network inspect command shows the containers, by id, in its results. You can specify an alternate format to execute a given template for each result. Go's text/template package describes all the details of the format.

$ sudo docker network inspect bridge

docker network inspect --verbose for swarm mode overlay networks shows service-specific details such as the service's VIP and port mappings. It also shows IPs of service tasks, and the IPs of the nodes where the tasks are running.

Following is an example output for an overlay network ov1 that has one service s1 attached to. service s1 in this case has three replicas.

$ docker network inspect --verbose ov1
