Create an ssh daemon service

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.

You can also get this sshd container by using :

docker pull dhrp/sshd

The password is 'screencast'

# Hello! We are going to try and install openssh on a container and run it as a servic 
# let's pull base to get a base ubuntu image. 
$ docker pull base
# 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 base /bin/bash
# now let's commit it 
# which container was it?
$ docker ps -a |more

# 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 
$ docker stop 0ebf7cec294755399d063f4b1627980d4cbff7d999f0bc82b59c300f8536a562
