Kanister

description Kanister Overview

Kanister is an open-source framework for application-level data management on Kubernetes. It defines data operations through APIs, Kubernetes custom resources, and reusable blueprints that can describe tasks such as backup, restore, copy, and application-specific preparation. The framework is intended for Kubernetes operators and application teams that need storage-aware workflows for stateful services, including workflows that transfer backup data to object storage.

help Kanister FAQ

What is Kanister used for in Kubernetes?

Kanister provides application-level data management for Kubernetes workloads. It can describe backup, restore, copy, and application-preparation operations.

How does Kanister define a backup workflow?

Kanister uses Kubernetes custom resources, APIs, and reusable blueprints to describe data operations. A blueprint can encode application-specific steps instead of treating every workload as a generic volume.

Can Kanister restore an application as well as copy data?

Yes. Its operation model includes restore and copy tasks in addition to backup, with preparation steps for applications that need coordinated handling.

Is Kanister tied to one Kubernetes distribution?

Kanister is an open-source framework built around Kubernetes APIs and custom resources. That makes the workflow portable across Kubernetes environments, although storage and application integrations still need their own support.
