REM says "Extension Manager requires Docker!" when running in NAS Docker

[pkmccarthy]

Attempting to move Peter's RHEOS to this extension manager as it is his preferred method going forward..

Of course, installing on a synology NAS is a bit different...I have tried several docker run commands (not sure I am mapping the internal directory correctly so I have tried with changes to the -v mapping and without any mapping, it does not appear to be the issue)

I have tried with and without a gid mapping too... here are a few commands

docker run -d \ --network mvlan_network \ --restart unless-stopped \ --name roon-extension-manager \ -v /volume1/docker/roon-extension-manager/data:/home/node/.rem/ \ -v /var/run/docker.sock:/var/run/docker.sock \ -e "TZ=America_Phoenix" \ theappgineer/roon-extension-manager:v1.x-standalone

docker run -d \ --network mvlan_network \ --restart unless-stopped \ --name roon-extension-manager \ --group-add 100 \ -v /volume1/docker/roon-extension-manager/data:/rem \ -v /var/run/docker.sock:/var/run/docker.sock \ -e "TZ=America/Phoenix" \ theappgineer/roon-extension-manager:v1.x-standalone

and a screen shot of the error message:

attempting to click SETTINGS will crash the ROON app (using the Windows App for testing)

thanks, Patrick

This error means that the extension cannot communicate with the Docker daemon. This should be taken care of by the -v /var/run/docker.sock:/var/run/docker.sock option, make sure there is a file on your NAS named /var/run/docker.sock or investigate were else it is located. If you run the command as a normal user (not root) then make sure that the 100 gid is correct.

I have a similar issue: I install roon-extension-manager using a Docker-Compose file, and it shows up properly in the Extensions menu. I can open the settings and choose an extension to download from the repository. However, immediately upon clicking save, the roon-extension-manager settings window closes, bringing me back to the main Extensions menu, and only then does the "Extension Manager requires Docker" message appear. The extension I chose to install is not installed.

My docker-compose.yml:

version: '2.4'
services:
  rem:
    image: theappgineer/roon-extension-manager:v1.x-standalone
    container_name: rem
    group_add:
      - 993
    environment:
      - TZ=America/New_York
    volumes:
      - rem_data:/home/node/.rem/
      - /var/run/docker.sock:/var/run/docker.sock
    network_mode: host
    restart: unless-stopped
volumes:
  rem_data:

Thank you for the quick response and sorry for the delay. Been re-re-building the home network. I suspect my issue is because I am running a macvlan on the host and I do not have a bridge network between these hosts and docker.. I will try to get to testing this sometime in the future and report back if this is the issue.
