Init Containers run before the main application containers start in a Pod.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Init containers are used to perform setup tasks before the main application containers start. They run to completion in sequence, in the order defined, and the Pod does not proceed to start the regular containers until every init container has finished successfully. This ensures the environment the main containers rely on is prepared, such as preloading data, waiting for a service to become available, or configuring resources. If any init container fails, the Pod will not start the main containers, and the init phase may retry according to the pod’s restart policy. Only after all init containers complete does the Pod transition to running and the main containers begin.
