What is the Kubernetes CSI (Container Storage Interface) and what problem does it solve?

Accepted Answer

The Container Storage Interface (CSI) solves the problem of storage vendor lock-in by providing a standard interface for developing plugins. This enables vendors to create drivers without modifying Kubernetes core code. The correct answer is right because it highlights CSI's role in facilitating out-of-tree storage driver development. Incorrect options misrepresent CSI's purpose, such as being a built-in storage driver or a security standard.
