Looking For Opinions on Docker + Letsencrypt + Reverse Proxy Setup (kbin.social)

I've been running 2 linodes for a number of years now - one has my website (wordpress) on it and one has a Foundry VTT server running. Both are separate linodes, and I use Google Domains to point [site.tld] to the wordpress VPS and foundry.[site.tld] to the other linode.

For a few services I run at home within my own network (Sonarr, Lidarr, Plex, etc.) I've started to use Docker and Portainer, and I like how easy it is to set things up (and remove them if they don't work). I'd like to redo my VPS similarly - I'd like to have a single linode, as a Docker host, and have the main domain point to a Wordpress container, a subdomain point to a Foundry container, and be able to easily add other containers for something like freshrss, etc. My goal is to be able to quickly spin up a docker via a compose file (portainer would be preferred), have it automatically reach out to letsencrypt to get a cert for the relevant subdomain, and have that subdomain point to that docker container.

I've been doing some searching around, and there seem to be a number of options, things like nginx reverse proxy, traefik, etc. and there are a lot of conflicting results.

Does anyone here have an opinion on this or some advice as to what the best option to look into might be?

I have a setup very similar to what you described in terms of having several web geegaws hiding behind a proxy, with Docker to manage them all. Foundry is even part of my setup as well (speaking of which, join https://lemmy.ml/c/FoundryVTT it's still pretty dead in there but one of the reddit mods came over and while they're not promoting things they're keeping an eye on them).

The proxy server of choice is very much matter of taste.

  • I use Caddy, which is very modern, simple to configure, and automatically handles letsencrypt cert setup out of the box.
  • Nginx is almost as modern, more flexible/powerful, IMO less beginner-friendly to setup, and has letsencrypt automation but not out of the box. Nginx is probably most common these days.
  • I know less about traefik, I feel like that's most often employed as a kubernetes ingress... but maybe people use it for other stuff and I just haven't encountered it. I do feel like outside of k8s, it's MUCH less common than nginx.
  • Good ole apache is great if you know how to use it. It's a bit archaic to configure compared to nginx or caddyz and though it is supremely capable, I do not recommend it unless you're already steeped in its ways.

There's a hundred other options as well, but it's really just preference for a toy setup like ours. I've used many of these things and prefer Caddy for my homelab stuff cause it's dreamily simple to configure. If I wasn't using Caddy, I'd be using nginx just because it's so commonly used that you can find help/instructions for anything you can imagine.

Thank you! Caddy rings a bell as well - I will add that to the list. My current main site is still behind apache...it took my forever to figure out how to get it working so I've been afraid to touch it. I definitely don't think I want to go down that route again if at all possible.

Naaah, Caddy is way simpler than Apache. It'll be much easier. Take a quick look at the docs and you'll see what I mean.
