KA-B002: Missing CPU limits

Warning Best Practice

Why This Matters

The container does not define a CPU limit. Without CPU limits, the container can consume unlimited CPU on the node, potentially starving other workloads. CPU limits ensure fair resource sharing and prevent runaway processes from impacting co-located pods.

How to Fix

Add a CPU limit to the container resources

Before (incorrect)

containers:
  - name: app
    image: myapp:1.0
    resources:
      requests:
        cpu: 100m

After (correct)

containers:
  - name: app
    image: myapp:1.0
    resources:
      requests:
        cpu: 100m
      limits:
        cpu: 500m
