      I have been trying to install the karsten13/magicmirror docker image on my synology NAS. I’ve tried with docker run scripts ssh’d in as root as well as normal compose method.

      The image always fails with this error in the log “mkdir: cannot create directory ‘/opt/magic_mirror/modules/default’: Permission denied”

      I can install and run the older bastilimbach/docker-magicmirror image without this error, but it is no longer supported and the custom css doesn’t properly load anymore with this image.

      Any advice would be greatly appreciated, I feel like I’m banging my head against a wall with this!

        this turned out to be a permissions problem. the folder was created w the synology user, but the container is running as user 1000

          to understand what is happening I need

          • the full logs of the container
          • the start command (full docker run ... or compose file)

            @karsten13 of course thanks for checking it out.

            Here is the docker start command:

            docker run  -d \
                --name magicmirror \
                --publish 8036:8080 \
                --restart unless-stopped \
                -e TZ=America/Chicago \
                --volume /volume1/docker/magicmirror/config:/opt/magic_mirror/config \
                --volume /volume1/docker/magicmirror/modules:/opt/magic_mirror/modules \
                --volume /volume1/docker/magicmirror/css:/opt/magic_mirror/css \
                karsten13/magicmirror:latest
            

            and here are the logs of the container:

              looks like the volumes on the host were created by root. The user in the container runs as user node with uid/gid 1000.

              So you can try

              a) cd to /volume1/docker/ on the host and run chown -R 1000:1000 ./magicmirror (you have to do this as root)

              or

              b) run the container as user root, you have to add

                  --user root \
              

              to the docker run ... command

                      I have the same issue but I do not really know how to run the container as user node with uid/gid 1000.

                      You wrote two ways with the hint that this should happen as root. How do I do this?

                      And can I make this run just for the MagicMirror docker? Because I have other dockers with other uids/gids.

                      Thanks for your help.

                        @pauabaer just change the docker compose .env file userid number from 1000 to whatever it is on your synology nas ( mine is 1026)
                        (note the . in front of env)

                          @pauabaer yes, the user info is separate for each docker container

                          think of a docker container as a mini pc disc, memory, cpu and software all inside a little case (container shell)
