Flux

Flux is the CNCF Graduated project: the definitive GitOps toolkit for continuous, progressive delivery on Kubernetes.

Flux is the GitOps engine that automates your application deployment and cluster configuration, ensuring your Kubernetes cluster state always matches the source repository. This CNCF Graduated project integrates directly with your existing infrastructure (GitHub, GitLab, Bitbucket) and OCI artifacts. It provides a robust, auditable, and traceable path for every change: simply commit to Git and Flux handles the reconciliation. Deploy with confidence, manage complex, multi-tenant environments, and eliminate configuration drift using this proven automation platform.
