Overview

This guide will explain how to set up Light Store behind a Caddy reverse proxy with HTTPS.
Caddy automatically obtains and renews SSL certificates for HTTPS support.

What this guide covers

We'll configure Caddy to:

1. Act as a reverse proxy, forwarding requests to Light Store running on port 8001
2. Automatically manage HTTPS certificates
3. Redirect HTTP traffic to HTTPS

DNS Configuration

Before setting up Caddy, configure your domain's DNS to point to your server:

1. Log in to your domain registrar's control panel (e.g., Cloudflare, GoDaddy, Namecheap)
2. Add an A record:
   • Type: A
   • Name: @ (for root domain) or store (for store.yourdomain.com)
   • Value: Your server's IP address
   • TTL: Auto or 3600 (1 hour)

Installing Caddy

On Ubuntu/Debian, install Caddy from the official repo:

sudo apt update
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo tee /etc/apt/trusted.gpg.d/caddy-stable.asc
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

Setting up Caddy Configuration

1. Open the Caddyfile:

sudo nano /etc/caddy/Caddyfile

2. Add this configuration (replace your.domain.com with your domain):

your.domain.com {
	reverse_proxy localhost:8001
}

3. Reload Caddy to apply the config:

sudo systemctl reload caddy

After doing these steps, the app should be available at https://your.domain.com.
