🔗 Easily connecting to BEAM nodes in Kubernetes with kubectl-beam

A kubectl plugin that makes connecting to Erlang and Elixir nodes running in Kubernetes pods as easy as running a single command---with full TTY support and Observer GUI.

Debugging BEAM applications in Kubernetes has always been more painful than it should be. You know the drill: your Phoenix app is misbehaving in production, you need to inspect some process state, maybe run a few commands in an IEx shell, or fire up Observer to see what’s going on. Simple enough on your local machine, right? But in Kubernetes, you end up manually port-forwarding EPMD, figuring out the dynamic distribution port, wrestling with DNS resolution, and praying your terminal doesn’t get mangled in the process.

I’ve done this dance too many times—enough to finally build something that handles all the tedious bits automatically. That’s why I created kubectl-beam, a kubectl plugin that connects you to BEAM nodes running in Kubernetes pods with a single command.
