What is Flux2?

Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories and OCI artifacts), 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, used in production by various organisations and cloud providers.

• Under the Settings section, select and provide appropriate details and clck -> Next button.

• Under the Application values page section, check the default values and add values if any required to be configured explicitly. Finally click on the + Add Application to deploy the Flux2 application to the user cluster.
