186+ ## OpenEBS Operator
187+
188+ OpenEBS primarily provides container attached block storage (iSCSI volumes) by leveraging/aggregating the
189+ storage on the nodes, with the storage controller itself running as a container. Different storage engines
190+ (Jiva & cStor) are supported, with tools available to dynamically provision Kubernetes Local PVs.
191+ The volumes are dynamically provisioned via PersistentVolumeClaims and are managed by a control plane component
192+ called "maya", which also runs as a deployment in the K8s cluster. In addition to maya, a typical OpenEBS
193+ installation comprises several other resources, which aid with various functionalities, ranging from snapshotting
194+ to disk management. All these components are described briefly below:
195+
196+ * **Maya-API-Server** - A storage orchestrator which integrates into Kubernetes workflow to help provision
197+ and manage OpenEBS Jiva & cStor (storage engine) volumes
198+
199+ * **Dynamic-OpenEBS-Provisioner** - A Kubernetes external storage provisioner that utilizes APIs exposed by maya-apiserver
200+ to perform provision & delete operations of Jiva & cStor volumes
201+
202+ * **Dynamic-LocalPV-Provisioner** - A dynamic provisioner for Kubernetes Local PVs
203+
204+ * **OpenEBS-Snapshot-Operator** - A Kubernetes snapshot controller that creates & restores OpenEBS volume snapshots
205+
206+ * **Node-Disk-Manager** - A disk management controller which identifies available disks, maintains inventory, and
207+ dynamically attaches/detaches disks to backend storage pods
208+
209+ The helm-based OpenEBS Operator eases the setup of all the above mentioned components, with a simple custom resource
210+ provided to define the install options, thereby enabling applications to start using the OpenEBS storageclasses in
211+ their PVCs. The OpenEBSInstallTemplate CR can be used to specify start-up parameters & also update/overwrite the
212+ definitions post install.
