KA-B004: Missing memory limits
Warning Best Practice
Why This Matters
The container does not define a memory limit. Without memory limits, the container can consume unlimited memory on the node, potentially causing OOM kills of other pods. Setting memory limits equal to requests enables the Guaranteed QoS class for predictable scheduling.
How to Fix
Add a memory limit to the container resources
