Exercise - 8

You are required to create a pod that requests a certain amount of CPU and memory, so it gets scheduled to-a node that has those resources available.

• Create a pod named nginx-resources in the pod-resources namespace that requests a minimum of 200m CPU and 1Gi memory for its container
• The pod should use the nginx image
• The pod-resources namespace has already been created

Solution

controlplane $ kubectl create ns pod-resources
namespace/pod-resources created

controlplane $ kubectl run nginx-resources --image=nginx --dry-run=client -o yaml > nginx-res.yaml

controlplane $ kubectl apply -f nginx-res.yaml
