Flux is a Kubernetes-native GitOps toolkit designed to manage and automate infrastructure and application deployments using Git as the source of truth. It continuously watches Git repositories for changes to configuration files, then applies and reconciles those changes within Kubernetes clusters. This guarantees that the live state of the system always matches what’s defined in Git, providing a reliable, auditable, and repeatable deployment workflow.

Flux supports multi-tenancy, progressive delivery, and secure secrets handling, making it suitable for both simple and complex production environments. It integrates seamlessly with tools like Helm, Kustomize, and SOPS, and is built to scale across teams and clusters. Maintained under the CNCF, Flux is a core enabler of modern GitOps practices, used by organizations aiming for high automation, traceability, and operational stability in their cloud native infrastructure.
