Extended description

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.
