Deploy Caddy

Deploy and Host Caddy on Railway

Caddy is an open-source web server. It is written in Go and runs as one static binary. Caddy serves static files, operates as a reverse proxy, and can get TLS certificates automatically.

About Hosting Caddy

This template deploys a static website with Caddy from the alphasecio/caddy-server GitHub repository. The site/ directory contains the website files. The Caddyfile contains the server configuration. Railway supplies HTTPS for your Railway domain and your custom domains. Caddy receives plain HTTP from the Railway edge, so you do not need to configure TLS certificates. To change the website, replace the files in site/ and push the changes to your repository.

Common Use Cases

• Static websites: Serve HTML, CSS, images, and fonts with one small configuration file.
• Landing pages and portfolios: Deploy a fast personal website or project page without a web framework.
• Reverse proxy: Change the Caddyfile to send requests to other services in your Railway project.

Implementation Details

The template uses the official Caddy 2 Docker image based on Alpine Linux. The configuration does these tasks:

• Listens on the port in the PORT variable. Railway sets this variable automatically.
• Serves the files that the Dockerfile copies from site/ into the image.
• Compresses responses with zstd and gzip.
• Adds basic security headers to all responses.
• Disables the Caddy admin API.
• Runs Caddy as a non-root user.

For the full configuration, refer to the Caddyfile and the Dockerfile.
