+The [ProvisioningRequest](https://github.com/kubernetes/autoscaler/blob/cluster-autoscaler-1.34.1/cluster-autoscaler/proposals/provisioning-request.md) introduces a Kubernetes-native way for Cluster Autoscaler to request new capacity without talking directly to cloud provider APIs.
+Instead of embedding provider-specific logic, the autoscaler simply describes the capacity it needs, and an external provisioner decides how to create the required nodes.
+This makes scaling portable across clouds, on-prem platforms, and custom provisioning systems, while greatly reducing complexity inside the autoscaler.
+
+Once the cluster has been provisioned, install the `ProvisioningRequest` definition.

+# Kamaji and `externalClusterReference` usage
+
+This document explains how to use **Kamaji's `externalClusterReference`** together with **Cluster API (CAPI)** to run Kubernetes control planes on an **external cluster**, while managing worker nodes from a management cluster.
+
+It assumes the use of the KubeVirt infrastructure provider for ease of deployment and local testing.
+
+---
+
+## High-level Architecture
+
+The following setup operates on **two Kubernetes clusters**:
+
+- **Management cluster** – runs Cluster API controllers and the Kamaji control-plane provider, and manages cluster lifecycle and topology.
+- **External cluster** - runs Kamaji, hosts the Kubernetes control plane components and receives control plane workloads via Kamaji
+
+---
+
+## Prerequisites
+
+- `docker`
+- `kind`
+- `kubectl`
+- `clusterctl`
+- `helm`
+
+---
+
+## Step 1: Create the KIND clusters
+
+Create the **management** cluster:
+
+```bash
+kind create cluster --name management
+```
+
+Create the **external** cluster that will host control planes:
+
+```bash
+kind create cluster --name external
+```
+
+Verify contexts:
+
+```bash
+kubectl config get-contexts
+```
+
+---
+
+## Step 2: Initialize Cluster API controllers
+
+Switch to the management cluster:
+
+```bash
+kubectl config use-context kind-management
+```
+
+Enable ClusterClass support and initialize Cluster API with Kamaji and KubeVirt:
+
+```bash
+export CLUSTER_TOPOLOGY=true
+clusterctl init \
+  --core cluster-api \
+  --bootstrap kubeadm \
+  --infrastructure kubevirt \
+  --control-plane kamaji
+```
+
+---
+
+## Step 3: Enable Kamaji external cluster feature gates
+
+Patch the Kamaji controller to enable `externalClusterReference`:
+
+```bash
+kubectl -n kamaji-system patch deployment capi-kamaji-controller-manager \
+  --type='json' \
+  -p='[
+    {
+      "op": "replace",
+      "path": "/spec/template/spec/containers/0/args/1",
+      "value": "--feature-gates=ExternalClusterReference=true,ExternalClusterReferenceCrossNamespace=true"
+    }
+  ]'
+```
+
+---
+
+## Step 4: Install KubeVirt
+
+Fetch the latest stable KubeVirt version and install:
+
+```bash
+export VERSION=$(curl -s "https://storage.googleapis.com/kubevirt-prow/release/kubevirt/kubevirt/stable.txt")
+kubectl apply -f "https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-operator.yaml"
+kubectl apply -f "https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-cr.yaml"
+```
+
+Enable emulation (optional, if virtualization is not supported):
+
+```bash
+kubectl -n kubevirt patch kubevirt kubevirt \
+  --type=merge \
+  --patch '{"spec":{"configuration":{"developerConfiguration":{"useEmulation":true}}}}'
+```
+
+---
+
+## Step 5: Prepare kubeconfig for the external cluster
+
+Retrieve the external cluster control-plane address:
+
+```bash
+EXT_CP_IP=$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' "external-control-plane")
+```
+
+Export and rewrite the kubeconfig:
+
+```bash
+kubectl --context kind-external config view --raw --minify --flatten > kind-external.kubeconfig
+```
+
+Replace the API endpoint with the cluster IP, required for cross-cluster access from the management cluster:
+
+```bash
+bash -c "sed -i -E 's#https://[^:]+:[0-9]+#https://$EXT_CP_IP:6443#g' kind-external.kubeconfig"
+```
+
+Create the kubeconfig secret in the management cluster:
+
+```bash
+kubectl -n default create secret generic kind-external-kubeconfig \
+  --from-file=kubeconfig=kind-external.kubeconfig
+```
+
+---
+
+## Step 6: Install Kamaji and dependencies on the external cluster
+
+Switch context:
+
+```bash
+kubectl config use-context kind-external
+```
+
+Install cert-manager:
+
+```bash
+helm upgrade --install cert-manager jetstack/cert-manager \
+  --namespace cert-manager \
+  --create-namespace \
+  --set installCRDs=true
+```
+
+Install Kamaji:
+
+```bash
+helm upgrade --install kamaji clastix/kamaji \
+  --namespace kamaji-system \
+  --create-namespace \
+  --set 'resources=null' \
+  --version 0.0.0+latest
+```
+
+Install MetalLB:
+
+```bash
+kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.15.3/config/manifests/metallb-native.yaml
+```
+
+Configure MetalLB IP address pool:
+
+```bash
+SUBNET=$(docker network inspect kind | jq -r '.[0].IPAM.Config[] | select(.Subnet | test(":") | not) | .Subnet' | head -n1)
+NET_PREFIX=$(echo "$SUBNET" | cut -d/ -f1 | awk -F. '{print $1"."$2}')
+kubectl apply -f - <<EOF
+apiVersion: metallb.io/v1beta1
+kind: IPAddressPool

+  name: default
+  namespace: metallb-system

+---
+apiVersion: metallb.io/v1beta1
+kind: L2Advertisement
+metadata:
+  name: default
+  namespace: metallb-system
+EOF
+```
+
+Create tenant namespace:
+
+```bash
+kubectl create namespace kamaji-tenants
+```
+
+---
+
+## Step 7: Definition of KamajiControlPlaneTemplate
+
+The `KamajiControlPlaneTemplate` is defined in [the following manifest](https://raw.githubusercontent.com/clastix/kamaji/master/config/capi/clusterclass-kubevirt-kamaji-external.yaml) and can be applied directly.
+
+This template configures how Kamaji deploys and manages the tenant control plane on an external Kubernetes cluster using Cluster API.
+
+```bash
+apiVersion: controlplane.cluster.x-k8s.io/v1alpha1
+kind: KamajiControlPlaneTemplate
+metadata:
+  name: kamaji-controlplane-external
+  namespace: default
+spec:
+  template:
+    spec:
+      addons:
+        coreDNS: {}
+        konnectivity: {}
+        kubeProxy: {}
+      dataStoreName: "default" # reference to DataStore present on external cluster
+      deployment:
+        externalClusterReference:
+          deploymentNamespace: kamaji-tenants
+          kubeconfigSecretName: kind-external-kubeconfig
+          kubeconfigSecretKey: kubeconfig
+      network:
+        serviceType: LoadBalancer
+      kubelet:
+        cgroupfs: systemd
+        preferredAddressTypes:
+        - InternalIP
+      registry: "registry.k8s.io"
+```
+
+The `.spec.template.spec.deployment.externalClusterReference` section defines how Kamaji connects to and deploys control plane components into the external cluster:
+
+- `deploymentNamespace` - The namespace on the external cluster where `TenantControlPlane` resources and control plane components are created.
+- `kubeconfigSecretName` - The name of the Kubernetes Secret containing a kubeconfig that allows Kamaji to authenticate to the external cluster.
+- `kubeconfigSecretKey` - The key inside the secret that holds the kubeconfig data.
+
+The referenced secret must exist in the Kamaji management cluster and provide sufficient permissions to create and manage resources in the target external cluster.
+
+---
+
+## Step 8: Create the Cluster
+
+Switch context back to the management cluster:
+
+```bash
+kubectl config use-context kind-management
+```
+
+Apply the Cluster manifest:
+
+```bash
+kubectl apply -f "https://raw.githubusercontent.com/clastix/kamaji/master/config/capi/clusterclass-kubevirt-kamaji-external.yaml"
+```
+
+---
+
+## Validation
+
+Check tenant control plane pods running in the external cluster:
+
+```bash
+kubectl --context kind-external -n kamaji-tenants get pods
+```
+
+Check cluster status in the management cluster:
+
+```bash
+kubectl --context kind-management get clusters
+kubectl --context kind-management get kamajicontrolplanes
+```
+
+Get cluster kubeconfig and confirm it is working:
+
+```bash
+kubectl config use-context kind-management
+clusterctl get kubeconfig demo-external > demo-external.kubeconfig
+KUBECONFIG=./demo-external.kubeconfig kubectl get nodes
+```
+
+---
+
+## Clean up
+
+Delete Kind clusters:
+
+```bash
+kind delete cluster --name management
+kind delete cluster --name external
+```
+
+---
+
+## Summary
+
+Using `externalClusterReference` with Kamaji and Cluster API enables:
+
+- Hosted Kubernetes control planes on remote clusters
+- Strong separation of concerns
+- Multi-cluster management patterns
+- Clean integration with ClusterClass

+# Datastore Overrides
+
+Kamaji offers the possibility of having multiple ETCD clusters backing different resources of the k8s api server by configuring the [`--etcd-servers-overrides`](https://kubernetes.io/docs/reference/command-line-tools-reference/kube-apiserver/#:~:text=%2D%2Detcd%2Dservers%2Doverrides%20strings) flag. This feature can be useful for massive clusters to store resources with high churn in a dedicated ETCD cluster.
+
+## Install Datastores
+
+Create a self-signed cert-manager `ClusterIssuer`.
+```bash
+echo 'apiVersion: cert-manager.io/v1
+kind: ClusterIssuer
+metadata:
+  name: self-signed
+spec:
+  selfSigned: {}
+' | kubectl apply -f -
+```
+
+Install two Datastores, a primary and a secondary that will be used for `/events` resources.
+```bash
+ helm install etcd-primary clastix/kamaji-etcd -n kamaji-etcd --create-namespace \
+   --set selfSignedCertificates.enabled=false \
+   --set certManager.enabled=true \
+   --set certManager.issuerRef.kind=ClusterIssuer \
+   --set certManager.issuerRef.name=self-signed
+```
+
+For the secondary Datastore, use the cert-manager CA created by the `etcd-primary` helm release.
+```bash
+ helm install etcd-secondary clastix/kamaji-etcd -n kamaji-etcd --create-namespace \
+   --set selfSignedCertificates.enabled=false \
+   --set certManager.enabled=true \
+   --set certManager.ca.create=false \

+   --set certManager.issuerRef.kind=ClusterIssuer \
+   --set certManager.issuerRef.name=self-signed
+```
+
+## Create a Tenant Control Plane
+
+Using the `spec.dataStoreOverrides` field, Datastores different from the one used in `spec.dataStore` can be used to store specific resources.

+# Gateway API
+
+Kamaji provides built-in support for the [Gateway API](https://gateway-api.sigs.k8s.io/), allowing Tenant Control Planes to be exposed as SNI-based addresses/urls. This eliminates the need for a dedicated LoadBalancer IP per TCP. A single Gateway resource can be used for multiple Tenant Control Planes and provide access to them with hostname-based routing (like `https://mycluster.xyz.com:6443`).
+
+You can configure Gateway in Tenant Control Plane via `tcp.spec.controlPlane.gateway`, Kamaji will automatically create a `TLSRoute` resource with corresponding spec. To make this configuration work, you need to ensure `gateway` exists (is created by you) and `tcp.spec.controlPlane.gateway` points to your gateway.
+
+We will cover a few examples below on how this is done.
+
+
+## Prerequisites
+
+Before using Gateway API mode, please ensure:
+
+1. **Gateway API CRDs are installed** in your cluster (Required CRDs: `GatewayClass`, `Gateway`, `TLSRoute`)
+
+2. **A Gateway resource exists** with appropriate configuration (see examples in this guide):
+    - Listeners for kube-apiserver.
+    - Use TLS protocol with Passthrough mode
+    - Hostname (or Hostname pattern) matching your Tenant Control Plane hostname
+
+3. (optional) **DNS is configured** to resolve hostnames (or hostname pattern) to the Gateway's LoadBalancer IP address. (This is needed for worker nodes to join, for testing we will use host entries in `/etc/hosts` for this guide)
+
+4. **Gateway controller is running** (e.g., Envoy Gateway, Istio Gateway, etc.)
+
+To replicate the guide below, please install [Envoy Gateway](https://gateway.envoyproxy.io/docs/tasks/quickstart/).
+
+Next, create a gateway resource:
+
+#### Gateway Resource Setup
+
+Your Gateway resource must have listeners configured for the control plane. Here's an example Gateway configuration:
+
+```yaml
+apiVersion: gateway.networking.k8s.io/v1
+kind: GatewayClass
+metadata:
+  name: envoy-gw-class
+spec:
+  controllerName: gateway.envoyproxy.io/gatewayclass-controller
+---
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: gateway
+  namespace: default
+spec:
+  gatewayClassName: envoy-gw-class
+  listeners:
+  - name: kube-apiserver
+    port: 6443
+    protocol: TLS
+    hostname: 'tcp1.cluster.dev'
+    tls:
+      mode: Passthrough
+    allowedRoutes:
+      kinds:
+      - group: gateway.networking.k8s.io
+        kind: TLSRoute
+      namespaces:
+        from: All
+```
+The above gateway is configured with envoy gateway controller. You can achieve the same results with any other gateway controller that supports `TLSRoutes` and TLS passthrough mode.
+
+The rest of this guide focuses on TCP. 
+
+## TenantControlPlane Gateway Configuration
+
+Enable Gateway API mode by setting the `spec.controlPlane.gateway` field in your TenantControlPlane resource:
+
+```yaml
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-1
+spec:
+  controlPlane:
+
+    # ... gateway configuration:
+    gateway:
+      hostname: "tcp1.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+        sectionName: kube-apiserver
+        port: 6443
+      additionalMetadata:
+        labels:
+          environment: production
+        annotations:
+          example.com/custom: "value"
+
+    # ... rest of the spec
+    deployment:
+      replicas: 1
+    service:
+      serviceType: ClusterIP
+  dataStore: default
+  kubernetes:
+    version: v1.29.0
+    kubelet:
+      cgroupfs: systemd
+  networkProfile:
+    port: 6443
+    certSANs:
+    - "tcp1.cluster.dev"  # make sure to set this.
+  addons:
+    coreDNS: {}
+    kubeProxy: {}
+
+```
+
+**Required fields:**
+
+- `hostname`: The hostname that will be used for routing (must match Gateway listener hostname pattern)
+- `parentRefs`: Array of Gateway references
+
+**Optional fields:**
+
+- `additionalMetadata.labels`: Custom labels to add to TLSRoute resources
+- `additionalMetadata.annotations`: Custom annotations to add to TLSRoute resources
+
+!!! info
+    ### Verify
+
+    From our kubectl client machine / remote machines we can access the cluster above with the hostname.
+    
+    **Step 1:** Fetch load balancer IP of the gateway.
+
+    `kubectl get gateway gateway -n default -o jsonpath='{.status.addresses[0].value}'`
+
+    **Step 2:** Add host entries in `/etc/hosts` with the above hostname and gateway LB IP.
+
+    `echo "<LB_IP> tcp1.cluster.dev" | sudo tee -a /etc/hosts`
+
+    **Step 3:** Fetch kubeconfig of tcp cluster.
+
+    `kubectl get secrets  tcp-1-admin-kubeconfig -o jsonpath='{.data.admin\.conf}' | base64 -d > kubeconfig`
+
+    **Step 4:** Test connectivity:
+    
+    `kubectl --kubeconfig kubeconfig cluster-info`
+
+
+
+### Multiple Tenant Control Planes
+
+We can use the same Gateway resource for multiple Tenant Control Planes by using different hostnames per tenant cluster.
+Let us extend the above example for multiple tenant control planes behind single gateway (and LB IP).
+
+```yaml
+# Gateway with wildcard hostname
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: gateway
+spec:
+  listeners:
+  - name: kube-apiserver
+    port: 6443
+    # note: we changed to wildcard hostname pattern matching
+    # for cluster.dev
+    hostname: '*.cluster.dev'
+  
+  # ...
+---
+# Tenant Control Plane 1
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-1
+spec:
+  controlPlane:
+    gateway:
+      hostname: "tcp1.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+  # ...
+---
+# Tenant Control Plane 2
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-2
+spec:
+  controlPlane:
+    gateway:
+      hostname: "tcp2.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+  # ...
+```
+
+Each Tenant Control Plane needs to use a different hostname. For each TCP, Kamaji creates a `TLSRoutes` resource with the respective hostnames, all `TLSRoutes` routing through the same Gateway resource.
+
+
+### Konnectivity
+
+If konnectivity addon is enabled, Kamaji creates a separate TLSRoute for it. But this is hardcoded with the listener name `konnectivity-server` and port `8132`. All gateways mentioned in `spec.controlPlane.gateway.parentRefs` must contain a listener with the same configuration for the given hostname. Below is example configuration:
+```yaml
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: gateway
+  namespace: default
+spec:
+  gatewayClassName: envoy-gw-class
+  listeners:
+  - ...
+  - ...
+  - name: konnectivity-server
+    port: 8132
+    protocol: TLS
+    hostname: 'tcp1.cluster.dev'
+    tls:
+      mode: Passthrough
+    allowedRoutes:
+      kinds:
+      - group: gateway.networking.k8s.io
+        kind: TLSRoute
+      namespaces:
+        from: All
+```

+        namespace: flux-system
+```
+
+!!! note "CRD Management Options"
+    The kamaji chart includes CRDs in its `crds/` directory. Using the separate kamaji-crds chart is optional and beneficial for:
+
+    - GitOps workflows requiring separate CRD lifecycle management
+    - Organizations with policies requiring separate CRD approval
+    - Scenarios where CRD updates must precede operator updates
+
+    For standard installations, using the kamaji chart alone is sufficient.
+
 ## Flux as the GitOps operator
 
 As GitOps ensures a constant reconciliation to a Git-versioned desired state, [Flux](https://fluxcd.io) can satisfy the requirement of those scenarios. In particular, the controllers that reconcile [resources](https://fluxcd.io/flux/concepts/#reconciliation) support communicating to external clusters.

+# Write Permissions
+
+Using the _Write Permissions_ section, operators can limit write operations for a given Tenant Control Plane,
+where no further write actions can be made by its tenants.
+
+This feature ensures consistency during maintenance, migrations, incident recovery, quote enforcement,
+or when freezing workloads for auditing and compliance purposes.
+
+Write Operations can limit the following actions:
+
+- Create
+- Update
+- Delete
+
+By default, all write operations are allowed.
+
+## Enabling a Read-Only mode
+
+You can enable ReadOnly mode by setting all the boolean fields of `TenantControlPlane.spec.writePermissions` to `true`.
+
+```yaml
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: my-control-plane
+spec:
+  writePermissions:
+    blockCreate: true
+    blockUpdate: true
+    blockDelete: true
+```
+
+Once applied, the Tenant Control Plane will switch into `WriteLimited` status.
+
+## Enforcing a quota mode
+
+If your Tenant Control Plane has a Datastore quota, this feature allows freezing write and update operations,
+but still allowing its tenants to perform a clean-up by deleting exceeding resources.
+
+```yaml
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: my-control-plane
+spec:
+  writePermissions:
+    blockCreate: true
+    blockUpdate: true
+    blockDelete: false
+```
+
+!!! note "Datastore quota"
+    Kamaji does **not** enforce storage quota for a given Tenant Control Plane:
+    you have to implement it according to your business logic.
+
+## Monitoring the status
+
+You can verify the status of your Tenant Control Plane with `kubectl get tcp`:
+
+```json
+$: kubectl get tcp k8s-133
+NAME      VERSION   INSTALLED VERSION   STATUS         CONTROL-PLANE ENDPOINT   KUBECONFIG                 DATASTORE   AGE
+k8s-133   v1.33.0   v1.33.0             WriteLimited   172.18.255.100:6443      k8s-133-admin-kubeconfig   default     50d
+```
+
+The `STATUS` field will display `WriteLimited` when write permissions are limited.
+
+## How it works
+
+When a Tenant Control Plane write status is _limited_, Kamaji creates a `ValidatingWebhookConfiguration` in the Tenant Cluster:
+
+```
+$: kubectl get validatingwebhookconfigurations
+NAME                       WEBHOOKS   AGE
+kamaji-write-permissions   2          59m
+```
+
+The webhook intercepts all API requests to the Tenant Control Plane and programmatically denies any attempts to modify resources.
+
+As a result, all changes initiated by tenants (such as `kubectl apply`, `kubectl delete`, or CRD updates) could be blocked.
+
+!!! warning "Operators and Controller"
+    When the write status is limited, all actions are intercepted by the webhook.
+    If a Pod must be rescheduled, the webhook will deny it.
+
+## Behaviour with limited write operations
+
+If a tenant user tries to perform non-allowed write operations, such as:
+
+- creating resources when `TenantControlPlane.spec.writePermissions.blockCreate` is set to `true`
+- updating resources when `TenantControlPlane.spec.writePermissions.blockUpdate` is set to `true`
+- deleting resources when `TenantControlPlane.spec.writePermissions.blockDelete` is set to `true`
+
+the following error is returned:
+
+```
+Error from server (Forbidden): admission webhook "catchall.write-permissions.kamaji.clastix.io" denied the request:
+the current Control Plane has limited write permissions, current changes are blocked:
+removing the webhook may lead to an inconsistent state upon its completion
+```
+
+This guarantees the cluster remains in a frozen, consistent state, preventing partial updates or drift.
+
+## Use Cases
+
+Typical scenarios where ReadOnly mode is useful:
+
+- **Planned Maintenance**: freeze workloads before performing upgrades or infrastructure changes.
+- **Disaster Recovery**: lock the Tenant Control Plane to prevent accidental modifications during incident handling.
+- **Auditing & Compliance**: ensure workloads cannot be altered during a compliance check or certification process.
+- **Quota Enforcement**: preventing Datastore quote over commit in terms of storage size.
+
+!!! info "Migrating the DataStore"
+    In a similar manner, when migrating a Tenant Control Plane to a different store, similar enforcement is put in place.
+    This is managed automatically by Kamaji: there's no need to toggle on and off the ReadOnly mode.
