Scaling a deployment using HPA

Deployment

1. Create namespace and deployments:

kubectl apply -f 00-namespace.yaml
kubectl apply -f 01-php-deployment.yaml

2. Inspect the pods once they are running:

kubectl get pods -n doit-lab-13
kubectl describe pod --selector run=php-apache -n doit-lab-13

3. Deploy the load generator:

kubectl apply -f 02-load-generator-pod.yaml

4. Check/wait until CPU and memory metrics are coming in:

watch -n 1 'kubectl top pod -n doit-lab-13'

5. Deploy the Horizontal Pod Autoscaler:

kubectl apply -f 03-php-hpa.yaml

6. Check/wait for scaleup:

kubectl get pod -n doit-lab-13 -w

Application Clean-Up

kubectl delete ns doit-lab-13
