What is the primary purpose of a sidecar container?

• A. To replace the main container entirely
• B. To run independently without any connection
• C. To enhance the functionality of the main container
• D. To manage data storage exclusively

Answer: (C)

The primary purpose of a sidecar container is to enhance the functionality of the main container. In a containerized environment, a sidecar container is typically used to add capabilities or features to the main application container without altering its core functionality. This might include tasks such as monitoring, logging, communication with external services, or managing networking aspects. By using a sidecar pattern, developers can decouple these additional responsibilities from the main application, allowing for better modularization, scalability, and maintainability. This setup enables the main container to focus solely on its primary tasks while the sidecar container takes care of ancillary responsibilities.
