# SSH Daemon Service
|
||
|
||
> **Note:**
|
||
> - This example assumes you have Docker running in daemon mode. For
|
||

|
||

|
||
|
||
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
