How to install Photo Prism on a Synology NAS using Container Manager (Docker Compose)

Another day, another photo app. My very unofficial install guide for Photo Prism on a Synology NAS. Using the official Docker Compose file provided by Photo Prism in order to install the app on a Synology with just Container Manager.
I highly recommend (and my recommendation is gold because I spend 15 minutes chewing gum in this video) trying this out with a small photo library to start. Or no photos at all. You can add photos through Photo Prism's user interface.
If you end up enjoying it and want to access your PhotoPrism (I think it's no space, ignore my spaces above) you'll want to look up using a reverse proxy or VPN on your NAS. Synology can actually provide you with a free domain name if you want to try using the reverse proxy method. I'm going to start putting in my descriptions that I'll make a tutorial on how to do that, but I'll never actually make that tutorial.
