Add docker-compose.yaml

This works on my machine, as long as I pass the correct KVM group to the container.

You could add a default of gid 109 to the docker compose file like this:

group_add:
  - "${KVM_GID:-109}"

And allow users to override wit KVM_GID in .env or from the environment:

KVM_GID=$(getent group kvm | cut -d: -f3) docker compose up
# or
echo "KVM_GID=$(getent group kvm | cut -d: -f3)" > .env
docker compose up
