# NAME
|
||
|
|
docker-network-connect - connect a container to a network
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
**docker network connect NAME CONTAINER**
|
||
|
|
|
||
|
|
[**--help**]
|
||
|
|

|
# DESCRIPTION
|
||
|
|
|
||
|
|
Connects a running container to a network. You can connect a container by name
|
||
|
|
or by ID. Once connected, the container can communicate with other containers in
|
||
|
|
the same network.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker network connect multi-host-network container1
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also use the `docker run --net=<network-name>` option to start a container and immediately connect it to a network.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker run -itd --net=multi-host-network busybox
|
||
|
|
```
|
||
|
|
|
||
|
|
You can pause, restart, and stop containers that are connected to a network.
|
||
|
|
Paused containers remain connected and a revealed by a `network inspect`. When
|
||
|
|
the container is stopped, it does not appear on the network until you restart
|
||
|
|
it. The container's IP address is not guaranteed to remain the same when a
|
||
|
|
stopped container rejoins the network.
|
||
|
|
|
||
|
|
To verify the container is connected, use the `docker network inspect` command. Use `docker network disconnect` to remove a container from the network.
|
||
|
|
|
||
|
|
Once connected in network, containers can communicate using only another
|
||
|
|
container's IP address or name. For `overlay` networks or custom plugins that
|
||
|
|
support multi-host connectivity, containers connected to the same multi-host
|
||
|
|
network but launched from different Engines can also communicate in this way.
|
||
|
|
|
||
|
|
You can connect a container to one or more networks. The networks need not be the same type. For example, you can connect a single container bridge and overlay networks.
