Prior to this change, the "docker network inspect" contains only the
endpoints that have active local container. This excludes all the remote
and stale endpoints. By including all the endpoints, it makes debugging
much simpler and also allows the user to cleanup any stale endpoints
using "docker network disconnect -f {network} {endpoint-name}".

# network inspect
|
|
|
|
Usage: docker network inspect [OPTIONS] NETWORK [NETWORK..]
|
|
|
|
Displays detailed information on a network
|
|
|
|
-f, --format= Format the output using the given go template.
|
|
--help Print usage
|
|
|
|
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:
|
|
|
|
```bash
|
|
$ 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. For networks backed by multi-host network driver, such as Overlay,
|
|
this command also shows the container endpoints in other hosts in the
|
|
cluster. These endpoints are represented as "ep-{endpoint-id}" in the output.
|
|
You can specify an alternate format to execute a given
|
|
template for each result. Go's
|
|
[text/template](http://golang.org/pkg/text/template/) package describes all the
|
|
details of the format.
|
|
|
|
```bash
|
|
$ sudo docker network inspect bridge
