Fleet

Fleet is a robust GitOps-at-scale engine developed by Rancher to streamline application deployment across thousands of Kubernetes clusters. Designed for platform engineers and DevOps teams, it utilizes a lightweight agent-based architecture to synchronize configurations directly from Git repositories to target environments. Its primary differentiator is the ability to manage massive, heterogeneous multi-cluster fleets with centralized policy enforcement and automated drift detection. By simplifying complex distribution workflows, Fleet ensures consistent operational standards across distributed infrastructure, making it an essential tool for large-scale enterprise Kubernetes management.
