Lab Information

The Nautilus DevOps team has noticed performance issues in some Kubernetes-hosted applications due to resource constraints. To address this, they plan to set limits on resource utilization. Here are the details:

Create a pod named httpd-pod with a container named httpd-container. Use the httpd image with the latest tag (specify as httpd:latest). Set the following resource limits:

Requests: Memory: 15Mi, CPU: 100m

Limits: Memory: 20Mi, CPU: 100m

Note: The kubectl utility on jump_host is configured to operate with the Kubernetes cluster.

Lab Solutions

Step 1: Create the HTTPD Pod with Resource Limits

Create the httpd pod with resource requests and limits

cat <<EOF | kubectl apply -f -
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"
    ports:
    - containerPort: 80
EOF

Step 2: Verification
Check if the pod is running:

kubectl get pod httpd-pod
kubectl describe pod httpd-pod
