Kubernetes CKA sample exam question 93 with answer

Question
Create a pod with specific volume type which only exists as long as Pod is running on that node.
Additional configuration:
Pod name: vol-test-pod
Namespace: web
Mount Point: /var/www/html

Answer
emptyDir volume is first created when a Pod is assigned to the node and lasts long until the Pod exists on that node.
You can grab the configuration from Kubernetes documentation page and adjust it as follows:

apiVersion: v1
kind: Pod
metadata:
  name: vol-test-pod
  namespace: web
spec:
  containers:
  - image: nginx
    name: nginx
    volumeMounts:
    - mountPath: /var/www/html
      name: test-vol
  volumes:
  - name: test-vol
    emptyDir: {}

Apply and verify:

kubectl apply -f po.yaml
kubectl get po -w
kubectl describe po vol-test-pod
