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 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. Flux supports multi-tenancy and support for syncing an arbitrary number of Git repositories.

The project supports the last three minor releases of the CLI and its controllers with critical bug and security fixes.

Release Cadence

Flux is at least released at the same rate as Kubernetes, following their cadence of three minor releases per year. After each Kubernetes minor release, the CLI and all controllers are tested against the latest Kubernetes version and are released approximately two weeks after Kubernetes. The newly released Flux version offers support for Kubernetes N-2 minor versions.
