Debian Base System

Build a Debian base system container image with Systemd and SSH remote access using Podman/Buildah.

Containers based on this image can be used as lightweight replacements for virtual machines.

Run the image build

To build a Debian 12 Bookworm image run

./build-container.sh

To build an image with a specific Debian version (bullseye, bookworm, trixie) run

./build-container.sh bullseye

Without placing a root/.ssh/authorized_keys file in the project directory the build script configures the SSH daemon for root access with the password admin. Otherwise SSH root login using a password is prohibited and restriced to the given SSH keys.

Run the container

Run the container with sshd listening on port 10022 for remote connections.

podman run --rm --detach --cap-add audit_write,audit_control -p=10022:22 localhost/debian-systemd-bookworm

Connect per SSH (host keys are newly created at the first container start).

ssh -p 10022 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@host.example.org 

Safety

Do not run setup.sh in your host system.
