How do you correctly specify an init container named init-setup in a Kubernetes Pod YAML?

AinitContainers: - name: init-setup image: alpine command: ['sh', '-c', 'echo Init']

Bcontainers: - name: init-setup image: alpine command: ['sh', '-c', 'echo Init']

CinitContainer: - name: init-setup image: alpine command: ['sh', '-c', 'echo Init']

DinitContainers: name: init-setup image: alpine command: ['sh', '-c', 'echo Init']

Step-by-Step Solution

Solution:

Step 1: Identify correct key
The correct key is initContainers (plural) at the Pod spec level.
Step 2: Validate YAML structure
Each init container is an item in the list under initContainers with proper indentation.
Step 3: Check options
B uses containers which is for main containers; C uses wrong key initContainer; D has wrong indentation and missing list dash.
Final Answer:
initContainers: - name: init-setup image: alpine command: ['sh', '-c', 'echo Init'] -> Option A
Quick Check:
Correct key is initContainers with list items [OK]

Quick Trick: Use 'initContainers' key with list of containers [OK]
