Application deployments with GitOps (Flux v2) for AKS and Azure Arc-enabled Kubernetes GitOps on Azure Arc-enabled Kubernetes or Azure Kubernetes Service uses Flux, a popular open-source tool set. Flux provides support for common file sources (Git and Helm repositories, Buckets, Azure Blob Storage) and template types (YAML, Helm, and Kustomize).
Flux is deployed directly on the cluster, and each cluster's control plane is logically separated.
This makes it scale well to hundreds and thousands of clusters. Flux enables pure pull-based GitOps application deployments. No access to clusters is needed by the source repo or by any other cluster.
