How does Michal Kuratczyk, Staff Software Engineer at RabbitMQ, access Kubernetes workloads securely, from anywhere? Regardless whether it's a Google Kubernetes Engine (GKE) cluster or Kubernetes in Docker (KiND), Tailscale is a simple solution for this particular use case. This also makes it easy to share private services with all devices on a tailnet, including with friends that want to access them on a smartphone.

![CDN PURGE with Elixir
https://makeitwork.tv π full version shipping any week now
We implement the following one-liner bash script the Elixir Wayβ’:
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 π https://github.com/thechangelog/changelog.com/pull/549
π€ 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.
πββοΈ THE SOLUTION: DNS lookups to discover all instances and coordinate purges across them.
π§βπ§ 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 π
π BUGS & PREDATORS (3:00): Undefined function errors, mock testing issues, and the classic double-slash URL bug. No Claude Code, just experience.
π§ DID IT WORK? (6:56): Lets force push straight into production and see what happens π±
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.
