feat: Add Docker Swarm configuration

[pveierland]

Hello,

The Docker Compose configuration provided in the documentation is not suitable for use with Docker Swarm due to its use of depends_on for startup sequencing, which is ignored in swarm mode. It would be great if a robust Docker Swarm configuration was provided that did not depend on this feature.
