$CDN PURGE with Elixir https://makeitwork.tv 👈 full version shipping any week now We implement the following one-liner bash script the Elixir Way™: dig cdn-2025-02-25.internal AAAA +short | while read ipv6; do curl -so /dev/null -w %{http_code} %{method} %{url_effective}n -X PURGE http://[$ipv6]:9000/; done Find the code and the conversation in this pull request 🐙 https://github.com/thechangelog/changelog.com/pull/549 🤔 THE PROBLEM: CDN is serving stale content, with some entries expired for over 4 minutes. We need a way to explicitly purge cache across all CDN instances rather than waiting for user requests to trigger refreshes. 🙇‍♂️ THE SOLUTION: DNS lookups to discover all instances and coordinate purges across them. 🧑‍🔧 THE DNS THING (02:26): Using Fly.ios internal DNS system, we implement IPv6 lookups to discover all CDN instances. Claude Code helps. It works the first time 🎉 🐞 BUGS & PREDATORS (3:00): Undefined function errors, mock testing issues, and the classic double-slash URL bug. No Claude Code, just experience. 🧐 DID IT WORK? (6:56): Lets force push straight into production and see what happens 😱 This session isnt just a tutorial - its an authentic look at collaborative coding, where DNS magic meets Elixir elegance to conquer distributed caching. If youre into DevOps, CDNs, or just love seeing bugs squashed in real time, this gives you the tools to understand (and maybe implement) your own purge system. 00:00 The Problem 00:46 The Solution 02:26 The DNS thing 03:00 Bugs & Predators 04:43 Lets fire this up 06:56 Lets force push it 07:25 Is it working? 08:53 No no no$
