In a Kubernetes Job, what does the parameter completions: 20 signify?

• A. It sets the maximum number of retries for failed pods.
• B. It defines the number of pods to run in parallel.
• C. It indicates that the job will create 20 pods overall to do the task.
• D. It determines the timeout for each pod.

Answer: (C)

Completions is about how many successful pod runs are required before the Job is considered finished. With completions set to 20, the Job will keep creating pods (within the limits of parallelism) until 20 of them complete successfully. The total number of pods started can be more than 20 if some attempts fail and are retried, or exactly 20 if every pod succeeds on the first try and no retries occur. Parallelism controls how many pods run at once, influencing how quickly those 20 successes happen. So this setting defines the target count of successful completions, not a fixed guarantee of exactly 20 pods being created.
