For single board systems / low memory systems, like the raspberry pi, I recommend only running a single celery worker. Celery is the task/worker component that handles all the searching and downloading behind the scenes.
If you skip this step, celery will use every available cpu (ie. the pi v4 has 4 cpus), which I’ve found is too much for the raspberry pi to handle.

docker-compose up -d
