Using Cloudflare R2 as an apt/yum repository

In this blog post, Sudarsan Reddy discusses using Cloudflare R2 as an apt/yum repository to distribute cloudflared (the Cloudflare Tunnel daemon) for Debian/Ubuntu and CentOS/RHEL systems. The author explains how apt-get works, including the role of Release files and Packages files in the process. They then describe how to create an apt repository by building a deb file out of the binary using fpm, generating plaintext files needed by apt with reprepro, uploading them to Cloudflare R2, and serving them from an R2 worker. The author concludes by providing a script for automating these steps in a release process.
