portainer only uses docker-compose in the newest versions (and only for x86_64) and still causes a ton of compatibility issues with way it handles things. It’s not something we will ever support deployment of containers with (though using it to view things is fine)
That said, beets isn’t a container that SHOULD have a problem, but again, we dont support portainer deployment so i will just say, if you can reproduce the original OP issue using docker-compose, we can definitely take a look at it.
