What is the difference between a Kubernetes Job’s completions and parallelism settings?

Accepted Answer

Completions and parallelism in Kubernetes Jobs serve distinct purposes. The correct answer, B, accurately describes completions as the number of successful pod completions and parallelism as the number of simultaneous pods. This enables controlled concurrency. Incorrect options misinterpret these settings, such as A, which confuses completions with timeouts, or C, which incorrectly states they are identical.
