Request: icloudpd

I’ve been looking for this type of container. But because I’m new to RasPi and Linux as a whole (4 weeks deep) I have no idea how to build the docker compose with all the required items. I tried walking through the config and everything. But it never works. CasaOS is constantly telling me it’s unhealthy. So please help a guy out. I just want to upload all my photos to my CasaOS external drive (I guess that’s a NAS?) so i can save money on the ever increasing icloud prices… Please and thanks.
