Kubernetes CKA sample exam question 1 with answer

Question

Answer

apiVersion: v1
kind: Pod
metadata:
  labels:
    run: admin-pod
  name: admin-pod
spec:
  containers:
  - command:
    - sleep
    - "3200"
    image: busybox
    name: admin-pod
    securityContext:
      capabilities:
        add: ["SYS_TIME"]

Run apply on definition file and check the pod details with describe.
