Setting up Caddy on a VPS

Fri, 05 Dec 2025 00:00:00 +0000

I use Caddy on my VPS because:

It’s simple to set up. No UI, just a config file.
It’s perfectly happy to run in a Docker container. I try to run everything as a Docker container. Makes things super simple to set up and update.
It automatically obtains SSL certificates from Let’s Encrypt. All the other popular open source reverse proxies do this too, nevertheless it’s a nice feature.

Docker Compose Setup

Create a Docker network to make mapping applications easier (see the Caddyfile explanation below). You’ll want to use this same network in any application hosted in Docker containers that use Caddy.
