KA-B003: Missing memory requests

Warning Best Practice

Why This Matters

The container does not define a memory request. Without memory requests, the Kubernetes scheduler cannot make informed placement decisions and the container falls into the BestEffort QoS class. It will be the first to be OOM-killed under node memory pressure.

How to Fix

Add a memory request to the container resources

Before (incorrect)

containers:
  - name: app
    image: myapp:1.0

After (correct)

containers:
  - name: app
    image: myapp:1.0
    resources:
      requests:
        memory: 128Mi
