Caddy Ninja – Setup an HTTPS-Enabled Web Server with Caddy on Alpine Linux

This guide provides a step-by-step process for setting up an HTTPS-enabled web server using Caddy on Alpine Linux. It begins with prerequisites, including ensuring that Alpine Linux is installed and that DNS records for the desired domain are correctly configured. The installation of Caddy is straightforward, requiring a single command to add the package. Configuration is done through the Caddyfile located in /etc/caddy, where users can set up security headers and error handling. The guide emphasizes the importance of including security headers for better protection, although they are not mandatory. It also details how to handle HTTP errors, specifically redirecting 404 errors to a designated page. The main configuration involves specifying the root directory for the website files and enabling file serving, along with importing the previously defined security headers and error handling snippets. Finally, the guide instructs users to enable Caddy to start on boot and to initiate the service, which will automatically request a Let's Encrypt certificate for secure HTTPS hosting. Once completed, users can visit their domain to verify that the website is live and secure.
