:title: Running an SSH service
:description: A screencast of installing and running an sshd service
:keywords: docker, example, package installation, networking
.. _running_ssh_service:
SSH Daemon Service
==================
.. include:: example_header.inc
**Video:**
I've create a little screencast to show how to create a sshd service
and connect to it. It is something like 11 minutes and not entirely
smooth, but gives you a good idea.
.. note::
This screencast was created before ``docker`` version 0.5.2, so the
daemon is unprotected and available via a TCP port. When you run
through the same steps in a newer version of ``docker``, you will
need to add ``sudo`` in front of each ``docker`` command in order
to reach the daemon over its protected Unix socket.

</div>
You can also get this sshd container by using
::
sudo docker pull dhrp/sshd
The password is 'screencast'
**Video's Transcription:**
.. code-block:: bash
# Hello! We are going to try and install openssh on a container and run it as a service
# let's pull ubuntu to get a base ubuntu image.
$ docker pull ubuntu
# I had it so it was quick
# now let's connect using -i for interactive and with -t for terminal
# we execute /bin/bash to get a prompt.
$ docker run -i -t ubuntu /bin/bash
# yes! we are in!
# now lets install openssh
$ apt-get update
$ apt-get install openssh-server
# ok. lets see if we can run it.
$ which sshd
# we need to create privilege separation directory
$ mkdir /var/run/sshd
$ /usr/sbin/sshd
$ exit
# now let's commit it
# which container was it?

# I gave the name dhrp/sshd for the container
# now we can run it again
$ docker run -d dhrp/sshd /usr/sbin/sshd -D # D for daemon mode
# is it running?
$ docker ps
# yes!
# let's stop it
