systemd docker compose startup helper

startup.sh runs docker compose for a list of services to bring containers up/down or to pull images.
container-startup.service is a one-shot systemd service which runs startup.sh up after boot as soon as the docker service is ready. Stop and restart are explicitly not part of the service, as those actions are handled by the docker daemon.

Configuration and Setup

Copy the template and add absolute paths to your docker-compose.yml files:
- cp services.conf.template services.conf
Install the service:
- ./install-service.sh
