Ubuntu is a Debian-based Linux operating system that runs from the desktop to the cloud, to all your internet connected things. It is the world's most popular operating system across public clouds and OpenStack clouds. It is the number one platform for containers; from Docker to Kubernetes to LXD, Ubuntu can run your containers at scale. Fast, secure and simple, Ubuntu powers millions of PCs worldwide.

This Docker container makes it easy to get an instance of SSHD up and running with Ubuntu.
Based on Official Ubuntu Docker Image with some minor hack:
- Packaging by Packer Docker builder and Ansible provisioner in single layer
- Handle
ENTRYPOINTwith catatonit - Handle
CMDwith SSHD
Start SSHD:
# Pull latest image
docker pull alvistack/ubuntu-24.04
# Run as detach
docker run \
-itd \
--name ubuntu \
--publish 2222:22 \
alvistack/ubuntu-24.04
Success. SSHD is now available on port 2222.
Because this container DIDN'T handle the generation of root
password, so you should set it up manually with pwgen by:
# Generate password with pwgen
PASSWORD=$(docker exec -i ubuntu pwgen -cnyB1); echo $PASSWORD
# Inject the generated password
echo "root:$PASSWORD" | docker exec -i ubuntu chpasswd
Alternatively, you could inject your own SSH public key into container's authorized_keys by:
# Inject your own SSH public key
(docker exec -i ubuntu sh -c "cat >> /root/.ssh/authorized_keys") < ~/.ssh/id_rsa.pub
Now you could SSH to it as normal:
ssh root@localhost -p 2222
