Dockerizing an SSH Daemon Service
The following Dockerfile sets up an SSHd service in a container that you
can use to connect to and inspect other container's volumes, or to get
quick access to a test container.
# sshd
#
# VERSION 0.0.1
FROM ubuntu
MAINTAINER Thatcher R. Peskens "thatcher@dotcloud.com"
# make sure the package repository is up to date
RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
RUN apt-get update
RUN apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' |chpasswd
EXPOSE 22
CMD /usr/sbin/sshd -D
Build the image using:
$ sudo docker build --rm -t eg_sshd .
Then run it. You can then use docker port to find out what host port
the container's port 22 is mapped to:
$ sudo docker run -d -P --name test_sshd eg_sshd
$ sudo docker port test_sshd 22
0.0.0.0:49154
And now you can ssh to port 49154 on the Docker daemon's host IP
address (ip address or ifconfig can tell you that):
$ ssh root@192.168.1.2 -p 49154
# The password is ``screencast``.
$$
Finally, clean up after your test by stopping and removing the container, and then removing the image.
$ sudo docker stop test_sshd
$ sudo docker rm test_sshd
$ sudo docker rmi eg_sshd
