Jiva Operator
OpenEBS Jiva Operator can be used to dynamically provision highly available Kubernetes Persistent Volumes using local (ephemeral) storage available on the Kubernetes nodes.
Overview
Jiva Operator helps with managing the lifecycle and operations on Jiva Volumes. Jiva Volumes are highly available block volumes that save the data to local storage available on the Kubernetes nodes. Jiva volumes replicate the volume data to multiple nodes to provide resiliency against node failures.
A Jiva Volume comprises of the following Kubernetes components:
- Jiva Controller Deployment and an associated Service.
- Jiva Replica StatefulSet with Hostpath Local PVs for saving the data.
- JivaVolume CR containing the status of the volume.
We are always happy to list users who run Jiva in production, check out our existing adopters.
