Simple Ubuntu docker images with SSH access

To create the image tutum/ubuntu with one tag per Ubuntu release, execute the following commands on the tutum-ubuntu branch:

docker build -t tutum/ubuntu:latest .

docker build -t tutum/ubuntu:lucid lucid/

docker build -t tutum/ubuntu:precise precise/

docker build -t tutum/ubuntu:quantal quantal/

docker build -t tutum/ubuntu:raring raring/

docker build -t tutum/ubuntu:saucy saucy/

docker build -t tutum/ubuntu:trusty trusty/

To run a container from the image you created earlier with the trusty tag binding it to port 2222 in all interfaces, execute:

docker run -d -p 0.0.0.0:2222:22 tutum/ubuntu:trusty

The first time that you run your container, a random password will be generated for user root. To get the password, check the logs of the container by running:

docker logs <CONTAINER_ID>

You will see an output like the following:

========================================================================
You can now connect to this Ubuntu container via SSH using:

    ssh -p <port> root@<host>
and enter the root password 'U0iSGVUCr7W3' when prompted

Please remember to change the above password as soon as possible!
========================================================================

In this case, U0iSGVUCr7W3 is the password allocated to the root user.

Done!

If you want to use a preset password instead of a random generated one, you can set the environment variable ROOT_PASS to your specific password when running the container:

docker run -d -p 2222:22 -e ROOT_PASS="mypass" tutum/ubuntu:trusty

If you want to use ssh key for login, you can use AUTHORIZED_KEYS environment variable. The public keys are separated by ,:

docker run -d -p 2222:22 AUTHORIZED_KEYS="pubkey1, pubkey2, pubkey3" tutum/ubunut:trusty

If you put the corresponding private key under ~/.ssh/ where you run ssh command, you will not be asked to input the password.
