can use to connect to and inspect other container's volumes, or to get
quick access to a test container.

Build the image using:
$ docker build -t eg_sshd .
```bash
$ docker build -t eg_sshd .
```
## Run a `test_sshd` container
Then run it. You can then use `docker port` to find out what host port
the container's port 22 is mapped to:
$ docker run -d -P --name test_sshd eg_sshd
$ docker port test_sshd 22
0.0.0.0:49154
```bash
$ docker run -d -P --name test_sshd eg_sshd
$ docker port test_sshd 22
0.0.0.0:49154
```
And now you can ssh as `root` on the container's IP address (you can find it
with `docker inspect`) or on port `49154` of the Docker daemon's host IP address
(`ip address` or `ifconfig` can tell you that) or `localhost` if on the
Docker daemon host:
$ ssh root@192.168.1.2 -p 49154
# The password is ``screencast``.
root@f38c87f2a42d:/#
```bash
$ ssh root@192.168.1.2 -p 49154
# The password is ``screencast``.
