Check if the specified host path exists and is the expected type

This error usually means that one of the paths does not exist.

Dockage does support relative mounts. Make sure that your file is indead in /opt/stacks/<stack name> as that is the path docker will be relating to.

Dockage supports relative paths but the question is relative to what. The relative path in the compose file in the Dockage container is relative to the location of the stacks directory in the container - i.e., the value of the DOCKGE_STACKS_DIR environment variable. This path is passed to your Docker host docker daemon when Dockge does (the equivalent of) docker compose up. If the path doesn't exist on your Docker host, you get the file not found error.

I'm running Dockge on my Synology. I mapped my Synology stacks directory to the same name in the Dockge container and set DOCKGE_STACKS_DIR appropriately. I.e.,:

services:
  dockge:
    image: louislam/dockge:latest
    container_name: dockge
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /volume1/docker/dockge/data:/app/data
      - /volume1/docker/dockge/stacks:/volume1/docker/dockge/stacks
        
    environment:
      # Tell Dockge where is your stacks directory
      - DOCKGE_STACKS_DIR=/volume1/docker/dockge/stacks

After doing this, relative paths work as expected. The same thing should work on any other Docker environment.
