Simple Ubuntu docker images with SSH access
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/
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!
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
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
