Simple Ubuntu docker images with SSH access (based on tutum/ubuntu)
To create the image execute the following command:
docker build -t myUbuntuNameGoesHere .
To run a container from the sorrell/sshubuntu image and bind it to port 2222 in all interfaces, execute:
docker run -d -p 0.0.0.0:2222:22 sorrell/sshubuntu
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" sorrell/sshubuntu
If you want to use your SSH key to login, you can use AUTHORIZED_KEYS environment variable. You can add more than one public key separating them by ,:
docker run -d -p 2222:22 -e AUTHORIZED_KEYS="``cat ~/.ssh/id_rsa.pub``" sorrell/sshubuntu
