Set Configuration Context

kubectl config use-context k8s

(Question)

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 pod-resources in the resources namespace that requests a minimum of 300m CPU and 1Gi memory for its container

• The pod should use the nginx image

• Check if the resources namespace has already been created

Solution - Click to expand!

# Check if namespace exist
kubectl get ns | grep resources

# Create namespace if not exist
kubectl create ns resources

# Create pod with requested configuration
kubectl run pod-resources -n resources --image=nginx --requests=cpu=300m,memory=1Gi

#Verify the configuration
kubectl describe po pod-resources -n resources | grep -i cpu
      cpu:        300m

kubectl describe po pod-resources -n resources | grep -i memory
      memory:     1Gi

kubectl describe po pod-resources -n resources | grep -i "image:"
    Image:          nginx
