Issue with Running Docker on unRAID

[UsamaWaheed]

Hi

I am trying to run the docker for this in unRAID - thank you for creating the template (based on Reddit request)

Here is the error that I am getting - not sure where I am going wrong.

I don't know much about unraid but I updated the template of you want to try again

Sorry for the late response.

Same error

Thinking out aloud - I dont think its the template interefering. I used CLI on unraid to create another docker for something else and the command I used are

docker run -d --name huntarr-sonarr \
  --restart always \
  -p 8988:8988 \
  -v /mnt/user/appdata/huntarr-sonarr:/config \
  -e API_KEY="your-api-key" \
  -e API_URL="http://your-sonarr-address:8989" \
  -e API_TIMEOUT="60" \
  -e MONITORED_ONLY="true" \
  -e HUNT_MISSING_SHOWS="1" \
  -e HUNT_UPGRADE_EPISODES="0" \
  -e SLEEP_DURATION="900" \
  -e STATE_RESET_INTERVAL_HOURS="168" \
  -e DEBUG_MODE="false" \
  -e ENABLE_WEB_UI="true" \
  -e SKIP_FUTURE_EPISODES="true" \
  -e SKIP_SERIES_REFRESH="false" \
  -e COMMAND_WAIT_DELAY="1" \
  -e COMMAND_WAIT_ATTEMPTS="600" \
  -e MINIMUM_DOWNLOAD_QUEUE_SIZE="-1" \
  -e RANDOM_MISSING="true" \
  -e RANDOM_UPGRADES="true" \
  huntarr/4sonarr:latest

Again just sharing the above as an example. I will do the CLI way for OCDarr.

[UsamaWaheed]

Just used the command line to run it

docker run -d --name OCDarr-CLI\
  --restart unless-stopped \
  -p 5002:5002 \
  -v /mnt/user/appdata/ocdarr-cli:/app \
  -v /mnt/user/appdata/ocdarr-cli/logs:/app/logs \
  -v /mnt/user/appdata/ocdarr-cli/config:/app/config \
  -v /mnt/user/appdata/ocdarr-cli/temp:/app/temp \
  -v /mnt/user/appdata/ocdarr-cli/static:/app/static \
  -v /mnt/user/appdata/ocdarr-cli/templates:/app/templates \
  -e SONARR_URL="http://192.168.*.*:8989" \
  -e SONARR_API_KEY="***********" \
  -e JELLYSEERR_URL="http://192.168.*.*:5055" \
  -e JELLYSEERR_API_KEY="***********" \
  -e RADARR_URL="http://192.168.*.*:7878" \
  -e RADARR_API_KEY="***********" \
  -e TMDB_API_KEY="***********" \
  -e PLEX_URL="http://192.168.*.*:32400" \
  -e PLEX_TOKEN="***********" \
  -e MAX_TMDB_ITEMS="24" \
  -e MAX_SHOWS_ITEMS="24" \
  -e MAX_MOVIES_ITEMS="24" \
  vansmak/ocdarr:amd64_dev

resulted in same error in the log

I've got a few things I need to figure out this week. For now try changing to this

<Overview>A Flask-based webhook listener that integrates Sonarr, Radarr, Jellyseerr and Plex for media management.</Overview>
  <Category>Tools: MediaServer</Category>
  
  <!-- Modified to ensure proper Python path -->
  <PostArgs>bash -c "cd /app && export PYTHONPATH=/app && python /app/webhook_listener.py"</PostArgs>

I encountered the same error when running OCDarr on Unraid:

ModuleNotFoundError: No module named 'webhook_listener'
[ERROR] Worker failed to boot.

In my case, the issue was caused by the Unraid template mounting an empty host directory over /app in the container, which overwrites the application code shipped with the Docker image.

Specifically, the template included this bind mount:

/mnt/user/appdata/ocdarr:/app

Since my /mnt/user/appdata/ocdarr was empty, the container started with an empty /app directory, and Gunicorn couldn’t find the webhook_listener module to start.

---

✅ Solution

I removed the /app bind mount (labeled as App directory in the template) so the container uses the application code that’s already included in the image.

I kept only the other mounts (like /app/logs, /app/config, /app/static, etc.) to persist configuration and logs.

After removing the /app mount, the container started correctly and the web UI was available.

[lukipopuki]

Ah, one more thing I ran into:

At first I kept getting this error when opening the Web UI:

jinja2.exceptions.TemplateNotFound: index.html

The reason turned out to be that my Unraid template mounted a host path over /app/templates:

/mnt/user/appdata/ocdarr/templates:/app/templates

However, the Docker image already contains the necessary templates and static files.
So by mounting an empty folder from the host, I effectively hid the built-in files.

Once I removed the mounts for /app/templates and /app/static, the Web UI loaded fine.
