Piraeus Datastore - High-Availability Datastore for Kubernetes

Piraeus is a high performance, highly-available, simple, secure, and cloud agnostic storage solution for Kubernetes.

The Piraeus Project consists of:

• A Kubernetes Operator to create, configure and maintain all components of Piraeus.
• A CSI Driver to provision persistent volumes and snapshots on the storage cluster maintained by Piraeus.
• A High Availability Controller to speed up the failover process of stateful workloads
• A Volume Affinity Controller, keeping Kubernetes Persistent Volumes reported affinity in sync with the cluster.
• Container images for the open source components Piraeus is built on:
  • DRBD is used as the underlying storage replication mechanism between cluster nodes. Documentation is provided by LINBIT.
  • LINSTOR creates and manages volumes on request of the CSI Driver, sets up replication using DRBD and prepares the backing storage devices. Documentation is provided by LINBIT.

Piraeus is a CNCF Sandbox Project.
