Description

We recently changed KCP to use a cached client to retrieve the Pods we care about.

This means we already have informers for Pods of workload clusters.

I'm wondering if we should also trigger reconciles if these Pods change (similar to how we watch on Node events in the Machine controller).

Pro

  • we can instantly react to Pod changes instead of using requeue after

Con

Research direction
Investigate how to add Pod event reconciliation to the KCP controller, considering informers and rate limiting strategies.
