Error in creating survey solution server in Docker

Hello there!

I am trying to set up a server in a Docker image, using a Synology NAS to host the data. The image is actually ran from Container Manager, but it allows to use the docker compose file to create a project with 2 containers (one for Survey, one for the DB using PostGres).

I used the docker-compose.yml version 3.8 from here: surveysolutions/surveysolutions - Docker Image | Docker Hub

Once creating the project with the docker compose file, I am prompted to create a project name and a path (for data I suppose) and I am also given the choice to provide HTTP/HTTPS services to the container. But in any cases I get this error message:

Error response from daemon: Bind mont failed: ‘/volume1/docker/test/AppData’ does not exist

Exit Code: 1

Any one with any clue?

Thanks a lot!
