Flux 2.9 release: new mirror and schema plugins
Flux 2.9.0 has been released, introducing new mirror and schema plugins. The update brings enhanced functionality for managing Kubernetes resources with these additional plugin options.
Background
Flux is an open-source tool for Kubernetes that automates deployment updates (GitOps). This means teams keep desired infrastructure config in Git repos, and Flux syncs the live cluster to match. Version 2.9 introduces two new plugin types: "mirror" (cache container images from external registries to avoid rate limits or outages) and "schema" (validate YAML configs before they hit the cluster). Plugins are reusable components that extend Flux's behavior. The release targets advanced users running Flux at scale, especially those in air-gapped environments or with strict validation needs.
