AThe metadata name is missing
BThe Pod is missing apiVersion
CThe container section is missing the 'name' field
DThe image name is invalid

  1. Step 1: Analyze error message

    The error 'containers must have a name' points to missing 'name' in container spec.

    Each container requires a unique name field; missing it causes deployment failure.

  3. Final Answer:

    Container section missing the 'name' field causes the error -> Option C

  4. Quick Check:

    Container name required in Pod YAML = true [OK]
Quick Trick: Always name containers in Pod YAML to avoid deployment errors [OK]
Common Mistakes:
  • Ignoring container name field
  • Assuming apiVersion or metadata name causes this error
  • Confusing image name errors with container name errors
