kazilotus/ubuntu repository overview

⁠Ubuntu

Simple Ubuntu docker images with SSH access

⁠Usage

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

docker build -t kazilotus/ubuntu:latest .
docker build -t kazilotus/ubuntu:bionic bionic/
docker build -t kazilotus/ubuntu:artful artful/
docker build -t kazilotus/ubuntu:xenial xenial/
docker build -t kazilotus/ubuntu:trusty trusty/

⁠Running kazilotus/ubuntu

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 kazilotus/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!

⁠Setting a specific password for the root account

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" kazilotus/ubuntu:trusty

⁠Adding SSH authorized keys

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`" kazilotus/ubuntu:trusty
