Custom Resources (CRDs)

Rook allows you to create and manage your storage cluster through custom resource definitions (CRDs). Each type of resource has its own CRD defined.

• Cluster: A Rook cluster provides the basis of the storage platform to serve block, object stores, and shared file systems.
• Pool: A pool manages the backing store for a block store. Pools are also used internally by object and file stores.
• Object Store: An object store exposes storage with an S3-compatible interface.
• File System: A file system provides shared storage for multiple Kubernetes pods.
