Kubernetes Pod Resource Limiting Guide

Set Resource Limits in Kubernetes Pods

How to Define Resource Restrictions for Kubernetes Pods

Steps

• Create a pod named httpd-pod with a container named httpd-container.

• Use the httpd image with the latest tag (httpd:latest).

• Set resource requests:

  • Memory: 15Mi

  • CPU: 100m

• Set resource limits:

  • Memory: 20Mi

  • CPU: 100m

Tasks

1. Create a manifest yaml file, httpd-pod.yaml

    apiVersion: v1
    kind: Pod
    metadata:
      name: httpd-pod
    spec:
      containers:
      - name: httpd-container
        image: httpd:latest
        resources:
          requests:
            memory: "15Mi"
            cpu: "100m"
          limits:
            memory: "20Mi"
            cpu: "100m"

   As I prefer EOF,

   
2. Apply the manifest file

    kubectl apply -f httpd-pod.yaml

   
3. pod/httpd-pod created. Now, Verify the Pod.

    kubectl get pods

   
4. Then, check the resources on given pod

    kubectl describe pod httpd-pod
