Have you ever configured resource limits in Kubernetes?

Yes, setting resource limits in Kubernetes is a common practice for controlling CPU and memory usage by containers.

In Kubernetes, you can specify:

• requests — the minimum guaranteed resources that a container will receive.
• limits — the maximum resources a container can use.

Example configuration in a Pod or Deployment manifest:

resources:
  requests:
    memory: "128Mi"
    cpu: "250m"
  limits:
    memory: "256Mi"
    cpu: "500m"

This helps to:

• Prevent a single container from consuming excessive resources.
• Ensure fair distribution of resources among applications.
• Improve cluster stability.

If a container exceeds its CPU limit, it will be throttled by the scheduler, and if it exceeds the memory limit, it may be killed (OOMKilled).
