Caddy Web Server on Ubuntu 24.04 LTS — Support & Quick Start

At a glance

Application ports	80 (HTTP), 443 (HTTPS)
Open in browser	http://<VM-IP>/
Service(s)	caddy
Configuration	/etc/caddy/Caddyfile (default site serves /usr/share/caddy on :80; put your domain as the site address and Caddy provisions HTTPS automatically)
Logs	journalctl -u caddy -f
Version	Caddy (official apt repository, current at build)
Platform	Ubuntu 24.04 LTS

Quick start

1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
2. Allow inbound SSH (22) for yourself plus the application port(s): 80 and 443 (HTTP/S) — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
3. Browse to http://<VM-IP>/ — Caddy answers immediately with the default site.
4. Set your domain and routes in /etc/caddy/Caddyfile and reload — automatic HTTPS needs DNS pointing at the VM and 80/443 open.

First login

1. No credential is generated: browse to http://<VM-IP>/ — Caddy serves the default page.
2. Edit /etc/caddy/Caddyfile (replace `:80` with your domain, add `reverse_proxy` or `file_server` directives), then `sudo systemctl reload caddy`; with DNS pointing at the VM and 80/443 open, Caddy obtains a Let's Encrypt certificate automatically.
