I’m not a docker pro, so I may be wrong…

It looks to me like your syntax is formatted as if you’re assigning an external bind mount, not a volume.

IIRC, volume mounts are <name>:<path_inside_container>, and docker will automatically pre-pend the service name to the vol name (e. g. /opt/docker/volumes/wireguard-<name>)

So, you could try something like:

volumes:
      - wireguard-server-config:/config
      - wireguard-modules:/lib/modules

ref: https://docs.docker.com/engine/storage/volumes/#use-a-volume-with-docker-compose

If I can offer an alternate perspective…

By making such concrete plans you may be ceding too much “control” to someone who you don’t yet know will have the same reliance on solid planning or respect for other’s time as you do.

So, if that’s the case, what can you do about it?

Plan differently.

Plan a one hour “date with yourself” that also works for you + a date.

Example: Make a plan to meet at a coffee shop or cheap bistro near a park… but bring a book/kindle/podcast/homework, or whatever you’d otherwise do on your own.

If they show, cool, you now have topics to discuss. If things are going well, continue over a walk in the park.

If they flake, cool, you’ve now got a solid hour to do something you enjoy, in a (hopefully) interesting place, and you’ve done it for cheap… Maybe take yourself on a walk in the park. :)

Hope that helps a bit.
