+
+                          While parents is not a listType `map`, this is due to the fact that the
+                          list key is not scalar, and Kubernetes is unable to represent this.
+
+                          Parent status MUST be considered to be namespaced by the combination of
+                          the parentRef and controllerName fields, and implementations should keep
+                          the following rules in mind when updating this status:
+
+                          * Implementations MUST update only entries that have a matching value of
+                            `controllerName` for that implementation.
+                          * Implementations MUST NOT update entries with non-matching `controllerName`
+                            fields.
+                          * Implementations MUST treat each `parentRef`` in the Route separately and
+                            update its status based on the relationship with that parent.
+                          * Implementations MUST perform a read-modify-write cycle on this field
+                            before modifying it. That is, when modifying this field, implementations
+                            must be confident they have fetched the most recent version of this field,
+                            and ensure that changes they make are on that recent version.

+                                map with a key of the `type` field _in the k8s apiserver_.
+

+
+                                * Implementations MUST perform a read-modify-write cycle on this field

+                                * Implementations MUST NOT remove or reorder Conditions that they are not
+                                  directly responsible for. For example, if an implementation sees a Condition
+                                  with type `special.io/SomeField`, it MUST NOT remove, change or update that
+                                  Condition.
+                                * Implementations MUST always _merge_ changes into Conditions of the same Type,
+                                  rather than creating more than one Condition of the same Type.
+                                * Implementations MUST always update the `observedGeneration` field of the
+                                  Condition to the `metadata.generation` of the Gateway at the time of update creation.
+                                * If the `observedGeneration` of a Condition is _greater than_ the value the
+                                  implementation knows about, then it MUST NOT perform the update on that Condition,
+                                  but must wait for a future reconciliation and status update. (The assumption is that

+
+                            While parents is not a listType `map`, this is due to the fact that the
+                            list key is not scalar, and Kubernetes is unable to represent this.
+
+                            Parent status MUST be considered to be namespaced by the combination of
+                            the parentRef and controllerName fields, and implementations should keep
+                            the following rules in mind when updating this status:
+
+                            * Implementations MUST update only entries that have a matching value of
+                              `controllerName` for that implementation.
+                            * Implementations MUST NOT update entries with non-matching `controllerName`
+                              fields.
+                            * Implementations MUST treat each `parentRef`` in the Route separately and
+                              update its status based on the relationship with that parent.
+                            * Implementations MUST perform a read-modify-write cycle on this field
+                              before modifying it. That is, when modifying this field, implementations
+                              must be confident they have fetched the most recent version of this field,
+                              and ensure that changes they make are on that recent version.

+                                  Conditions are a listType `map`, which means that they function like a

+
+                                  This means that implementations must obey some rules when updating this

+                                  * Implementations MUST NOT remove or reorder Conditions that they are not
+                                    directly responsible for. For example, if an implementation sees a Condition
+                                    with type `special.io/SomeField`, it MUST NOT remove, change or update that

+                                  * Implementations MUST always _merge_ changes into Conditions of the same Type,
+                                    rather than creating more than one Condition of the same Type.
+                                  * Implementations MUST always update the `observedGeneration` field of the
+                                    Condition to the `metadata.generation` of the Gateway at the time of update creation.
+                                  * If the `observedGeneration` of a Condition is _greater than_ the value the

+##  `ProvisioningRequest` support
+
+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.
+
+```

+# Kubeconfig Generator
+
+The **Kubeconfig Generator** is a Kamaji extension that simplifies the distribution of Kubeconfig files for tenant clusters managed through Kamaji.
+
+Instead of manually exporting and editing credentials, the generator automates the creation of kubeconfigs aligned with your organizational policies.
+
+## Motivation
+
+When managing multiple Tenant Control Planes (TCPs), cluster administrators often face two challenges:
+
+1. **Consistency**: ensuring kubeconfigs are generated with the correct user identity, groups, and endpoints
+2. **Scalability**: distributing kubeconfigs to users across potentially dozens of tenant clusters without manual steps
+
+The `KubeconfigGenerator` resource addresses these problems by:
+
+- Selecting which TCPs to target via label selectors.
+- Defining how to build user and group identities in kubeconfigs.
+- Automatically maintaining kubeconfigs as new tenant clusters are created or updated.
+
+This provides a single, declarative way to manage kubeconfig lifecycle across all your tenants,
+especially convenient if those cases where an Identity Provider can't be used to delegate access to Tenant Control Plane clusters.
+
+## How it Works
+
+### Selection
+
+- `namespaceSelector` filters the namespaces from which Tenant Control Planes are discovered.
+- `tenantControlPlaneSelector` further refines which TCPs to include.
+
+### Identity Definition
+
+The `user` and `groups` fields use compound values, which can be either:
+
+- A static string (e.g., `developer`)
+- A dynamic reference resolved from the TCP object (e.g., `metadata.name`)
+
+This allows kubeconfigs to be tailored to the cluster’s context or a fixed organizational pattern.
+
+### Endpoint Resolution
+
+The generator pulls the API server endpoint from the TCP’s `admin` kubeconfig.
+
+By default it uses the `admin.svc` template, but this can be overridden with the `controlPlaneEndpointFrom` field.
+
+### Status and Errors
+
+The resource keeps track of how many kubeconfigs were attempted, how many succeeded,
+and provides detailed error reports for failed generations.
+
+## Typical Use Cases
+
+- **Platform Operators**: automatically distribute kubeconfigs to developers as new tenant clusters are provisioned.
+- **Multi-team Environments**: ensure each team gets kubeconfigs with the correct groups for RBAC authorization.
+- **Least Privilege Principle**: avoid distributing `cluster-admin` credentials with a fine-grained RBAC
+- **Dynamic Access**: use `fromDefinition` references to bind kubeconfig identities directly to tenant metadata
+ (e.g., prefixing users with the TCP's name).
+
+## Example Scenario
+
+A SaaS provider runs multiple Tenant Control Planes, each corresponding to a different customer.
+Instead of manually managing kubeconfigs for every customer environment, the operator defines a single `KubeconfigGenerator`:
+
+```yaml
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: KubeconfigGenerator
+metadata:
+  name: tenant
+spec:
+  # Select only Tenant Control Planes living in namespaces
+  # labeled as production environments
+  namespaceSelector:
+    matchLabels:
+      environment: production
+  # Match all Tenant Control Planes in those namespaces
+  tenantControlPlaneSelector: {}
+  # Assign a static group "customer-admins"
+  groups:
+    - stringValue: "customer-admins"
+  # Derive the user identity dynamically from the TenantControlPlane metadata
+  user:
+    fromDefinition: "metadata.name"
+  # Use the public admin endpoint from the TCP’s kubeconfig
+  controlPlaneEndpointFrom: "admin.conf"
+```
+
+- Matches all TCPs in namespaces labeled `environment=production`.
+- Generates kubeconfigs with group `customer-admins`.
+- Derives the user identity from the TCP’s `metadata.name`.
+
+As new tenants are created, their kubeconfigs are generated automatically and kept up to date.
+
+```
+$: kubectl get secret --all-namespaces -l kamaji.clastix.io/managed-by=tenant
+NAMESPACE       NAME             TYPE     DATA   AGE
+alpha-tnt       env-133-tenant   Opaque   1      12h
+alpha-tnt       env-130-tenant   Opaque   1      2d
+bravo-tnt       prod-tenant      Opaque   1      2h
+charlie-tnt     stable-tenant    Opaque   1      1d
+```
+
+## Observability
+
+The generator exposes its status directly in the CRD:
+- `resources`: total number of TCPs targeted.
+- `availableResources`: successfully generated kubeconfigs.
+- `errors`: list of failed kubeconfig generations, including the affected resource and error message.
+
+This allows quick debugging and operational awareness.
+
+## Deployment
+
+The _Kubeconfig Generator_ is **not** enabled by default since it's still in experimental state.
+
+It can be enabled using the Helm value `kubeconfigGenerator.enabled=true` which is defaulted to `false`.

+# 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.
