Flux version 2
Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy.
Flux version 2 ("v2") is built from the ground up to use Kubernetes' API extension system, and to integrate with Prometheus and other core components of the Kubernetes ecosystem. In version 2, Flux supports multi-tenancy and support for syncing an arbitrary number of Git repositories, among other long-requested features.
Flux v2 is constructed with the GitOps Toolkit, a set of composable APIs and specialized tools for building Continuous Delivery on top of Kubernetes.
Flux is a Cloud Native Computing Foundation (CNCF) project.

The GitOps Toolkit is the set of APIs and controllers that make up the
runtime for Flux v2. The APIs comprise Kubernetes custom resources,
which can be created and updated by a cluster user, or by other
You can use the toolkit to extend Flux, or to build your own systems
