  "description": "## Creating and Using Secrets\n\nSecrets let you store sensitive data (passwords, tokens, keys) separately from your pod specs.\n\n**Your task:**\n\n1. Create a Secret named `app-secret` with the key `api-key` and value `supersecret`\n2. Create a Pod named `secret-reader` using `busybox:1.36` that:\n   - Mounts the secret key `api-key` as an environment variable named `API_KEY`\n   - Runs: `sleep 3600`\n\n**Verify:**\n```bash\nkubectl exec secret-reader -- env | grep API_KEY\n```",
