How to limit resources of containers in Kubernetes?

In Kubernetes, container resources are limited using the resources.requests and resources.limits fields in the Pod or Deployment manifest.

• requests are the minimum resources guaranteed to be allocated to the container.
• limits are the maximum resources the container cannot exceed.

Example of CPU and memory limits:

apiVersion: v1
kind: Pod
metadata:
  name: example-pod
spec:
  containers:
  - name: example-container
    image: nginx
    resources:
      requests:
        memory: "128Mi"
        cpu: "250m"
      limits:
        memory: "256Mi"
        cpu: "500m"

This approach helps manage load and prevent a single container from consuming excessive resources.
