The Secrets Store CSI Driver allows Kubernetes to mount secrets, keys, and certificates stored in external secrets stores, such as AWS Secrets Manager, Azure Key Vault, Google Cloud Secret Manager, and HashiCorp Vault, into pods as a volume. This enables secure and centralized secret management for applications running in Kubernetes. The driver leverages the Container Storage Interface (CSI) to achieve this integration.
This project supports mounting multiple secrets from various providers as a single volume, simplifying pod configuration. It provides a consistent interface for accessing secrets regardless of the underlying storage system. The driver is designed to handle portability by supporting SecretProviderClass CRDs, and supports both Linux and Windows containers. It’s tested with several providers using TestGrid.
- Multiple Secrets Stores: Supports AWS Secrets Manager, Azure Key Vault, GCP Secret Manager, and HashiCorp Vault.
- Multi-Provider Support: Facilitates deploying multiple providers within the same cluster.
- CSI Integration: Utilizes the Container Storage Interface for seamless Kubernetes volume management.
- Pod Portability: Enables fluid movement of pods between clusters using SecretProviderClass.
- Linux & Windows Support: Operates on both Linux and Windows-based containers.
- Secret Synchronization: Maintains a consistent state between Kubernetes secrets and external secrets stores.
- Extensible Architecture: Designed for easy addition of new secrets store providers.
The Secrets Store CSI Driver is an active project with ongoing development and maintenance. It has a good level of community engagement and regular testing coverage across multiple cloud providers. Recent commits and issue resolution indicate continued support and improvement.
The Secrets Store CSI Driver benefits organizations needing a secure and manageable way to integrate external secrets stores with Kubernetes. It simplifies secret management by providing a standardized volume interface, reducing complexity and enhancing security. This eliminates the need for manual secret injection or custom solutions.
