Overview
A Job is used for batch processing or short-lived tasks. Unlike a Deployment, which aims to keep Pods running indefinitely, a Job runs Pods until they complete their task and then stops them.
Key Features
- Completion Guarantee: Ensures the task is completed successfully, even if Pods fail or nodes go down.
- Parallelism: Can be configured to run multiple Pods in parallel to speed up the task.
- Retries: Automatically retries failed Pods up to a specified limit.
Use Cases
- Database migrations.
- Batch data processing.
- Sending a batch of emails.
