Rook was the first storage project accepted into the Cloud Native Computing Foundation (CNCF), and it helps storage administrators to automate everyday tasks like provisioning, configuration, disaster recovery, deployment, and upgrading storage providers. Rook turns a distributed file system into storage services that scale and heal automatically by leveraging the Kubernetes features with the operator pattern. When administrators use Rook with a storage provider like Ceph, they only have to worry about declaring the desired state of the cluster and the operator will be responsible for setting up and configuring the storage layer in the cluster.
