It functions as a set of controllers that monitor desired state in external sources and continuously reconcile the live cluster to match those definitions. The system distinguishes itself through a multi-cluster management plane that coordinates application delivery across fleets of remote clusters from a central hub. It provides a dedicated mechanism for automated image updates, which scans container registries for new tags and automatically commits updated references back to the configuration repository. Additionally, it includes a secret decryption pipeline that secures sensitive data in version control using PGP, Age, or cloud KMS providers. The project covers a broad range of delivery capabilities, including declarative Helm release management, Kustomize-based rendering, and infrastructure bootstrapping. It also provides integrated support for workload identity federation, artifact-based configuration, and event-driven synchronization via webhooks. Users can manage the delivery pipelines and cluster resources through a dedicated command line interface. ## Tags ### DevOps & Infrastructure - [Cluster Bootstrapping](https://awesome-repositories.com/f/devops-infrastructure/cluster-bootstrapping.md) — Performs the initial setup and configuration of a cluster, including the creation of a GitOps source repository.
