It is invaluable during exams when you need to recall the exact field name or understand what a field accepts.\n\n**Your task:**\n\nA ConfigMap has been created for you. Use `kubectl explain` to answer the following, then:\n\n1. Create a Pod named `explain-demo` using image `nginx:alpine`\n2. Set the pod's `spec.terminationGracePeriodSeconds` to **5** (use `kubectl explain pod.spec.terminationGracePeriodSeconds` to understand the field)\n\n```bash\n# Explore the pod spec:\nkubectl explain pod.spec\n\n# Inspect a specific field:\nkubectl explain pod.spec.terminationGracePeriodSeconds\n```",
