Kubernetes Custom Controller - Sidecar Shutdown

What is this?

This is a custom Kubernetes controller for the purpose of watching running pods, and sending a SIGTERM to sidecar containers when the "main" application container has exited (and the sidecars are the only non-terminated containers).

This is a response to kubernetes/kubernetes#25908.

Usage

  1. Deploy the controller into your cluster.
  2. Add the nrmitchi.com/sidecars annotation to your pods, with a comma-seperated list of sidecar container names.
