Kanister is a data protection workflow management tool. It provides a set of cohesive APIs for defining and curating data operations by abstracting away tedious details around executing data operations on Kubernetes. It's extensible and easy to install, operate and scale.

Highlights

✅ Kubernetes centric - Kanister's APIs are implemented as Custom Resource Definitions that conforms to Kubernetes' declarative management, security and distribution models.

✅ Storage agnostic - Kanister allows you to efficiently and securely transfer backup data between your services and the object storage service of your choice. Use Kanister to backup, restore, and copy your data using your storage's APIs, and Kanister won't get in the way.

✅ Asynchronous or synchronous task execution - Kanister can schedule your data operation to run asynchronously in dedicated job pods, or synchronously via Kubernetes apimachinery ExecStream framework.

✅ Re-usable workflow artifacts - A Kanister blueprint can be re-used across multiple workflows to protect different environment deployments.

✅ Extensible, atomic data operation functions - Kanister provides a collection of easy-to-use data operation functions that you can add to your blueprint to express detailed backup and restore operation steps, including pre-backup scaling down of replicas, working with all mounted volumes in a pod etc.

✅ Secured via RBAC - Prevent unauthorized access to your workflows via Kubernetes role-based access control model.

✅ Observability - Kanister exposes logs, events and metrics to popular observability tools like Prometheus, Grafana and Loki to provide you with operational insights into your data protection workflows.

Quickstart

Follow the instructions in the installation documentation, to install Kanister on your Kubernetes cluster.

Walk through the tutorial to define, curate and run your first data protection workflow using Kanister blueprints, actionsets and profiles.

The examples directory contains many sample blueprints that you can use to define data operations for:

The Kanister architecture is documented here.
