Flux is a continuous delivery and GitOps toolkit for Kubernetes. It keeps clusters synchronized with declarative configuration stored in Git repositories, OCI artifacts, Helm repositories and storage buckets, automatically reconciling changes so deployed resources match their desired state.
The software uses Kubernetes custom resources and specialized controllers to manage Kustomize configurations, Helm releases, image updates and notifications. It supports multi-tenancy, multiple configuration repositories and integration with Prometheus and other components of the Kubernetes ecosystem.
This is free and open source software.
