Setting up Caddy as a reverse proxy for my home lab

I’ve been juggling a Plex server, Nextcloud, and a little Go API all on the same Ubuntu 24.04 box. The goal was simple: a tidy public URL for each service, automatic HTTPS, and as little upkeep as possible. Caddy 2.7 fit the bill perfectly—its ACME integration is a one‑liner, and it ships with HTTP/2 out of the box.

1. Install Caddy

sudo apt update
sudo apt install -y debian-keyring debian-archive-keyring
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | \
  sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] \
  https://dl.cloudsmith.io/public/caddy/stable/deb/debian any main" | \
  sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install -y caddy

Caddy boots as a systemd service automatically. Just double‑check that it’s listening on the web ports:
