It's not possible to install it inside the container, since that would need some major changes. So don't install it with apt.

But you can use podman (which is almost identical to docker) on the host or install docker on the host.

To use podman:
host-shell pkexec podman
or:
host-shell podman
for rootless containers (in most cases the better choice)

If you really want to use docker instead of podman, run:

abroot pkg add docker.io
abroot pkg apply
reboot
host-shell pkexec docker

Something I ended up doing today was installing podman-compose in a container, that way I can use docker-compose files without needing full blown docker

Thanks for the hints @kbdharun! Found the discord thread. Combined with another user's reddit post, I pieced together a custom image that works out of the box with docker.

The key block is under modules in the recipe.yml:

modules:
  - name: init-setup
    type: shell
    commands:
      - lpkg --unlock
      - apt-get update

  - name: install-docker
    type: shell
    commands:
      - install -m 0755 -d /etc/apt/keyrings
      - curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
      - chmod a+r /etc/apt/keyrings/docker.asc
      - echo \
        "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian bookworm stable" > /etc/apt/sources.list.d/docker.list
      - cat /etc/apt/sources.list.d/docker.list
      - apt-get update
      - apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Hope that saves future visitors who need docker some time 🤞
