Tailscale could probably be easier but I wanted to make it easy for my parents.
I was trying to set it up via Reverse Proxy in Caddy. My stupid NAS has proprietary software and the only way to do it is in Docker but their version of docker has some wonky issues with ports.
Oh, I use caddy too. What gave you trouble?
It’s been a few weeks since I’ve tinkered with it but I plan on pulling it up today. If I remember right, it works fine if I launch it as a singular container by itself, but if I launch it inside a container with multiple apps, it says the ports are in use. I verified that no other app is using the ports. I checked in the CLI and it says containers is using the port. Very weird.
Following tutorials and researching online had been helpful by my NAS uses QNAP’s QTS operating system. It locks you out of many basic functions. I can’t install apps outside of its App Store unless it’s in a docker container, for example.
Many command line functions have also been removed so when I’m troubleshooting or looking for alternate fixes, I’m blocked out.
You nas doesn't support docker compose? Its kind of the only reason why you'd want to have several processes on the same container.
Ps.: can you ssh in?
I can use docker compose. I need them on the same container so they can see the other apps exist and direct traffic there. Or that I as my understanding.
I tried setting up Caddy on a separate container as Jellyfin but that didn’t work.
Would a docker-compose.yaml like this one work? https://privatebin.net/?1d1d30a1e92a974a#JDwvxcmJyjwmhir4YFvVrRGhn7fUJNqgTbrmgBYe1etC I just basically ripped that off my working setup. This sets up two containers that can see each other
