Add-Ons

Add-Ons are platform-curated capabilities that you opt into per-cluster. Each one is packaged as a wrapper Helm chart, registered as an Installable, and rolled out to a cluster by adding an Installation that targets that cluster.

📄️ CSI Addon

Install the platform's Azure Blob CSI driver on a cluster — provisions a `WorkloadIdentity` claim, role grants, and an `azureblob-default` StorageClass.

📄️ Istio Addon

The platform's Istio service mesh in ambient mode, with the Gateway API CRDs bundled — what lands on the cluster, the oauth2-proxy ext-authz wiring, optional observability, and the upgrade order.

📄️ Upgrading Istio

The specific steps needed for each Istio upgrade.
