Which cloud-native tools enable Kubernetes clusters to be automatically synchronised with Git repositories?

• A. Argo CD
• B. Argo CD & Flux
• C. Kustomize
• D. Helm

Answer: (B)

GitOps is about using a Git repository as the source of truth for your cluster, with automated agents continuously reconciling the cluster state to match what’s in that repo. Argo CD and Flux are built to do exactly this: they watch a Git repository, detect changes, and automatically apply those changes to Kubernetes clusters so the live state stays in sync with the desired state in Git. Argo CD provides a declarative way to define an application in Git and keep the cluster in sync, with options for automatic or manual syncing and clear health/status reporting. Flux does something similar through its GitOps Toolkit, offering reconciliation loops that monitor repos and apply manifests across clusters, including features like automated image updates. Kustomize and Helm, while useful for templating and packaging, respectively, do not by themselves continuously synchronize a cluster from a Git repository. Therefore, the tools that enable automatic synchronization from Git are Argo CD and Flux.
