NamespaceCleaner Controller

A basic loop-based Kubernetes controller that demonstrates how to watch and process custom resources.

What it does

This simple controller:

• Lists NamespaceCleaner custom resources using generated clients
• Runs a reconcile loop every 30 seconds to process each NamespaceCleaner

How to use

1. Setup your cluster and CRD:

   make setup

2. Create test namespaces (optional):

   make create-test-namespaces

3. Run the controller:

   make run-controller

What you'll see

The controller will:

• List all NamespaceCleaner resources on startup
• Every 30 seconds, scan for NamespaceCleaner resources
• For each resource, find matching namespaces based on label selectors
• Log what it would delete (but won't actually delete for safety)
