You are deploying a one-off data processing job to Azure Container Instances. The container should run to completion. If the process exits with code 0, it should not restart. If it fails with a non-zero exit code, it should automatically restart to retry. Which restart policy should you set?

The OnFailure restart policy is correct because it aligns with the requirement for the container to restart only if it fails (exits with a non-zero code). If the process completes successfully (exit code 0), it will not restart, fulfilling the "run to completion" aspect without unnecessary retries. Always would restart the container regardless of the exit code, even after successful completion, which is not desired. Never would prevent any restarts, even upon failure, contradicting the requirement for automatic retries. Manual is not a valid restart policy option for Azure Container Instances; restart policies are automated settings.
