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 installation

With Homebrew:

brew install fluxcd/tap/flux

With Bash:

curl -s https://toolkit.fluxcd.io/install.sh | sudo bash

# enable completions in ~/.bash_profile
. <(flux completion bash)

Arch Linux (AUR) packages:

flux-bin: install the latest stable version using a pre-build binary (recommended)
flux-go: build the latest stable version from source code
flux-scm: build the latest (unstable) version from source code from our git main branch

Binaries for macOS, Windows and Linux AMD64/ARM are available to download on the release page.

Verify that your cluster satisfies the prerequisites with:

flux check --pre

Get started

To get started with Flux, start browsing the documentation or get started with one of the following guides:

GitOps Toolkit

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 automation tooling.

You can use the toolkit to extend Flux, or to build your own systems for continuous delivery -- see the developer guides.
