+A Kubernetes in Kubernetes tool, k3k provides a way to run multiple embedded isolated k3s clusters on your kubernetes cluster.
 
-K3k, Kubernetes in Kubernetes, is a tool that empowers you to create and manage isolated K3s clusters within your existing Kubernetes environment.  It enables efficient multi-tenancy, streamlined experimentation, and robust resource isolation, minimizing infrastructure costs by allowing you to run multiple lightweight Kubernetes clusters on the same physical host. K3k offers both "shared" mode, optimizing resource utilization, and "virtual" mode, providing complete isolation with dedicated K3s server pods. This allows you to access a full Kubernetes experience without the overhead of managing separate physical resources. 
+**Experimental Tool**
 
-K3k integrates seamlessly with Rancher for simplified management of your embedded clusters.
+This project is still under development and is considered experimental. It may have limitations, bugs, or changes. Please use with caution and report any issues you encounter. We appreciate your feedback as we continue to refine and improve this tool.
 
+## Example
 
+An example on creating a k3k cluster on an RKE2 host using k3kcli
 
-## Features and Benefits
-
-- **Resource Isolation:** Ensure workload isolation and prevent resource contention between teams or applications. K3k allows you to define resource limits and quotas for each embedded cluster, guaranteeing that one team's workloads won't impact another's performance.
-
-- **Simplified Multi-Tenancy:** Easily create dedicated Kubernetes environments for different users or projects, simplifying access control and management. Provide each team with their own isolated cluster, complete with its own namespaces, RBAC, and resource quotas, without the complexity of managing multiple physical clusters.
-
-- **Lightweight and Fast:** Leverage the lightweight nature of K3s to spin up and tear down clusters quickly, accelerating development and testing cycles. Spin up a new K3k cluster in seconds, test your application in a clean environment, and tear it down just as quickly, streamlining your CI/CD pipeline.
-
-- **Optimized Resource Utilization (Shared Mode):** Maximize your infrastructure investment by running multiple K3s clusters on the same physical host. K3k's shared mode allows you to efficiently share underlying resources, reducing overhead and minimizing costs.
-
-- **Complete Isolation (Virtual Mode):** For enhanced security and isolation, K3k's virtual mode provides dedicated K3s server pods for each embedded cluster. This ensures complete separation of workloads and eliminates any potential resource contention or security risks.
-
-- **Rancher Integration:** Simplify the management of your K3k clusters with Rancher. Leverage Rancher's intuitive UI and powerful features to monitor, manage, and scale your embedded clusters with ease.
-
-
-## Installation
-
-This section provides instructions on how to install K3k and the `k3kcli`.
-
-
-### Prerequisites
-
-* [Helm](https://helm.sh) must be installed to use the charts. Please refer to Helm's [documentation](https://helm.sh/docs) to get started.
-* An existing [RKE2](https://docs.rke2.io/install/quickstart) Kubernetes cluster (recommended).
-* A configured storage provider with a default storage class.
-
-**Note:** If you do not have a storage provider, you can configure the cluster to use ephemeral or static storage. Please consult the [k3kcli advance usage](./docs/advanced-usage.md#using-the-cli) for instructions on using these options.
-
-### Install the K3k controller
-
-1. Add the K3k Helm repository:
-
-   ```bash
-   helm repo add k3k https://rancher.github.io/k3k
-   helm repo update
-   ```
-
-2. Install the K3k controller:
-
-   ```bash
-   helm install --namespace k3k-system --create-namespace k3k k3k/k3k
-   ```
-
-We recommend using the latest released version when possible.
-
-
-### Install the `k3kcli`
-
-The `k3kcli` provides a quick and easy way to create K3k clusters and automatically exposes them via a kubeconfig.
-
-To install it, simply download the latest available version for your architecture from the GitHub Releases page.
-
-For example, you can download the Linux amd64 version with:
-
-```
-wget -qO k3kcli https://github.com/rancher/k3k/releases/download/v1.0.1/k3kcli-linux-amd64 && \
-  chmod +x k3kcli && \
-  sudo mv k3kcli /usr/local/bin
-```
-
-You should now be able to run:
-```bash
--> % k3kcli --version
-k3kcli version v1.0.1
-```
-
-
-## Usage
-
-This section provides examples of how to use the `k3kcli` to manage your K3k clusters.
-
-**K3k operates within the context of your currently configured `kubectl` context.** This means that K3k respects the standard Kubernetes mechanisms for context configuration, including the `--kubeconfig` flag, the `$KUBECONFIG` environment variable, and the default `$HOME/.kube/config` file. Any K3k clusters you create will reside within the Kubernetes cluster that your `kubectl` is currently pointing to.
-
-
-### Creating a K3k Cluster
-
-To create a new K3k cluster, use the following command:
-
-```bash
-k3kcli cluster create mycluster
-```
-> [!NOTE]
-> **Creating a K3k Cluster on a Rancher-Managed Host Cluster**
->
-> If your *host* Kubernetes cluster is managed by Rancher (e.g., your kubeconfig's `server` address includes a Rancher URL), use the `--kubeconfig-server` flag when creating your K3k cluster:
->
->```bash
->k3kcli cluster create --kubeconfig-server <host_node_IP_or_load_balancer_IP> mycluster
->```
->
-> This ensures the generated kubeconfig connects to the correct endpoint.
-
-When the K3s server is ready, `k3kcli` will generate the necessary kubeconfig file and print instructions on how to use it.  
-
-Here's an example of the output:
-
-```bash
-INFO[0000] Creating a new cluster [mycluster]          
-INFO[0000] Extracting Kubeconfig for [mycluster] cluster 
-INFO[0000] waiting for cluster to be available..        
-INFO[0073] certificate CN=system:admin,O=system:masters signed by CN=k3s-client-ca@1738746570: notBefore=2025-02-05 09:09:30 +0000 UTC notAfter=2026-02-05 09:10:42 +0000 UTC 
-INFO[0073] You can start using the cluster with: 
-
-        export KUBECONFIG=/my/current/directory/mycluster-kubeconfig.yaml
-        kubectl cluster-info  
-```
-
-After exporting the generated kubeconfig, you should be able to reach your Kubernetes cluster:
-
-```bash
-export KUBECONFIG=/my/current/directory/mycluster-kubeconfig.yaml
-kubectl get nodes
-kubectl get pods -A
-```
-
-You can also directly create a Cluster resource in some namespace, to create a K3k cluster:
-
-```bash
-kubectl apply -f - <<EOF
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: mycluster
-  namespace: k3k-mycluster
-EOF
-```
-
-and use the `k3kcli` to retrieve the kubeconfig:
-
-```bash
-k3kcli kubeconfig generate --namespace k3k-mycluster --name mycluster 
-```
-
-
-### Deleting a K3k Cluster
-
-To delete a K3k cluster, use the following command:
-
-```bash
-k3kcli cluster delete mycluster
-```

 ## Architecture
 
-For a detailed explanation of the K3k architecture, please refer to the [Architecture documentation](./docs/architecture.md).
+K3K consists of a controller and a cli tool, the controller can be deployed via a helm chart and the cli can be downloaded from the releases page.
+
+### Controller
+
+The K3K controller will watch a CRD called `clusters.k3k.io`. Once found, the controller will create a separate namespace and it will create a K3S cluster as specified in the spec of the object.
+
+Each server and agent is created as a separate pod that runs in the new namespace.
+
+### CLI
+
+The CLI provides a quick and easy way to create K3K clusters using simple flags, and automatically exposes the K3K clusters so it's accessible via a kubeconfig.
+
+## Features
+
+### Isolation
+
+Each cluster runs in a sperate namespace that can be isolated via netowrk policies and RBAC rules, clusters also run in a sperate network namespace with flannel as the backend CNI. Finally, each cluster has a separate datastore which can be persisted.
+
+In addition, k3k offers a persistence feature that can help users to persist their datatstore, using dynamic storage class volumes.
+
+### Portability and Customization
+
+The "Cluster" object is considered the template of the cluster that you can re-use to spin up multiple clusters in a matter of seconds.
+
+K3K clusters use K3S internally and leverage all options that can be passed to K3S. Each cluster is exposed to the host cluster via NodePort, LoadBalancers, and Ingresses.

-For more in-depth examples and information on advanced K3k usage, including details on shared vs. virtual modes, resource management, and other configuration options, please see the [Advanced Usage documentation](./docs/advanced-usage.md).
+## Usage
+
+### Deploy K3K Controller
+
+[Helm](https://helm.sh) must be installed to use the charts.  Please refer to
+Helm's [documentation](https://helm.sh/docs) to get started.
+
+Once Helm has been set up correctly, add the repo as follows:
+
+```sh
+  helm repo add k3k https://rancher.github.io/k3k
+```
+
+If you had already added this repo earlier, run `helm repo update` to retrieve
+the latest versions of the packages.  You can then run `helm search repo
+k3k --devel` to see the charts.
+
+To install the k3k chart:
+
+```sh
+helm install my-k3k k3k/k3k --devel
+```
+
+To uninstall the chart:
+
+```sh
+helm delete my-k3k
+```
+
+**NOTE: Since k3k is still under development, the chart is marked as a development chart, this means that you need to add the `--devel` flag to install it.**
+
+### Create a new cluster
+
+To create a new cluster you need to install and run the cli or create a cluster object, to install the cli:
+
+#### For linux and macOS
+
+1 - Donwload the binary, linux dowload url:
+```
+wget https://github.com/rancher/k3k/releases/download/v0.0.0-alpha2/k3kcli
+```
+macOS dowload url:
+```
+wget https://github.com/rancher/k3k/releases/download/v0.0.0-alpha2/k3kcli
+```
+Then copy to local bin
+```
+chmod +x k3kcli
+sudo cp k3kcli /usr/local/bin
+```
+
+#### For Windows 
+
+1 - Download the Binary:
+Use PowerShell's Invoke-WebRequest cmdlet to download the binary:
+```powershel
+Invoke-WebRequest -Uri "https://github.com/rancher/k3k/releases/download/v0.0.0-alpha2/k3kcli-windows" -OutFile "k3kcli.exe"
+```
+2 - Copy the Binary to a Directory in PATH:
+To allow running the binary from any command prompt, you can copy it to a directory in your system's PATH. For example, copying it to C:\Users\<YourUsername>\bin (create this directory if it doesn't exist):
+```
+Copy-Item "k3kcli.exe" "C:\bin"
+```
+3 - Update Environment Variable (PATH):
+If you haven't already added `C:\bin` (or your chosen directory) to your PATH, you can do it through PowerShell:
+```
+setx PATH "C:\bin;%PATH%"
+```
+
+To create a new cluster you can use:
+
+```sh
+k3k cluster create --name example-cluster --token test
+```
 
 
-## Development
+## Tests
 
-If you're interested in building K3k from source or contributing to the project, please refer to the [Development documentation](./docs/development.md).
+To run the tests we use [Ginkgo](https://onsi.github.io/ginkgo/), and [`envtest`](https://book.kubebuilder.io/reference/envtest) for testing the controllers.
 
+Install the required binaries from `envtest` with [`setup-envtest`](https://pkg.go.dev/sigs.k8s.io/controller-runtime/tools/setup-envtest), and then put them in the default path `/usr/local/kubebuilder/bin`:
 
-## License
+```
+ENVTEST_BIN=$(setup-envtest use -p path)
+sudo mkdir -p /usr/local/kubebuilder/bin
+sudo cp $ENVTEST_BIN/* /usr/local/kubebuilder/bin
+```

-# Advanced Usage
-
-This document provides advanced usage information for k3k, including detailed use cases and explanations of the `Cluster` resource fields for customization.
-
-## Customizing the Cluster Resource
-
-The `Cluster` resource provides a variety of fields for customizing the behavior of your virtual clusters. You can check the [CRD documentation](./crds/crds.md) for the full specs.
-
-**Note:** Most of these customization options can also be configured using the `k3kcli` tool. Refer to the [k3kcli](./cli/k3kcli.md) documentation for more details.
-
-
-
-This example creates a "shared" mode K3k cluster with:
-
-- 3 servers
-- K3s version v1.31.3-k3s1
-- Custom network configuration 
-- Deployment on specific nodes with the `nodeSelector`
-- `kube-api` exposed using an ingress
-- Custom K3s `serverArgs`
-- ETCD data persisted using a `PVC`
-
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: my-virtual-cluster
-  namespace: my-namespace
-spec:
-  mode: shared
-  version: v1.31.3-k3s1
-  servers: 3
-  tlsSANs:
-    - my-cluster.example.com
-  nodeSelector:
-    disktype: ssd
-  expose:
-    ingress:
-      ingressClassName: nginx
-      annotations:
-        nginx.ingress.kubernetes.io/ssl-passthrough: "true"
-        nginx.ingress.kubernetes.io/backend-protocol: "true"
-        nginx.ingress.kubernetes.io/ssl-redirect: "HTTPS"
-  clusterCIDR: 10.42.0.0/16
-  serviceCIDR: 10.43.0.0/16
-  clusterDNS: 10.43.0.10
-  serverArgs:
-  - --tls-san=my-cluster.example.com
-  persistence:
-    type: dynamic
-    storageClassName: local-path
-```
-
-
-### `mode`
-
-The `mode` field specifies the cluster provisioning mode, which can be either `shared` or `virtual`. The default mode is `shared`.
-
-* **`shared` mode:** In this mode, the virtual cluster shares the host cluster's resources and networking. This mode is suitable for lightweight workloads and development environments where isolation is not a primary concern.
-* **`virtual` mode:** In this mode, the virtual cluster runs as a separate K3s cluster within the host cluster. This mode provides stronger isolation and is suitable for production workloads or when dedicated resources are required.
-
-
-### `version`
-
-The `version` field specifies the Kubernetes version to be used by the virtual nodes. If not specified, K3k will use the same K3s version as the host cluster. For example, if the host cluster is running Kubernetes v1.31.3, K3k will use the corresponding K3s version (e.g., `v1.31.3-k3s1`).
-
-
-### `servers`
-
-The `servers` field specifies the number of K3s server nodes to deploy for the virtual cluster. The default value is 1.
-
-
-### `agents`
-
-The `agents` field specifies the number of K3s agent nodes to deploy for the virtual cluster. The default value is 0.
-
-**Note:** In `shared` mode, this field is ignored, as the Virtual Kubelet acts as the agent, and there are no K3s worker nodes.
-
-
-### `nodeSelector`
-
-The `nodeSelector` field allows you to specify a node selector that will be applied to all server/agent pods. In `shared` mode, the node selector will also be applied to the workloads.
-
-
-### `expose`
-
-The `expose` field contains options for exposing the API server of the virtual cluster. By default, the API server is only exposed as a `ClusterIP`, which is relatively secure but difficult to access from outside the cluster.
-
-You can use the `expose` field to enable exposure via `NodePort`, `LoadBalancer`, or `Ingress`.
-
-In this example we are exposing the Cluster with a Nginx ingress-controller, that has to be configured with the `--enable-ssl-passthrough` flag.
-
-
-### `clusterCIDR`
-
-The `clusterCIDR` field specifies the CIDR range for the pods of the cluster. The default value is `10.42.0.0/16` in shared mode, and `10.52.0.0/16` in virtual mode.
-
-
-### `serviceCIDR`
-
-The `serviceCIDR` field specifies the CIDR range for the services in the cluster. The default value is `10.43.0.0/16` in shared mode, and `10.53.0.0/16` in virtual mode.
-
-**Note:** In `shared` mode, the `serviceCIDR` should match the host cluster's `serviceCIDR` to prevent conflicts and in `virtual` mode both `serviceCIDR` and `clusterCIDR` should be different than the host cluster.
-
-
-### `clusterDNS`
-
-The `clusterDNS` field specifies the IP address for the CoreDNS service. It needs to be in the range provided by `serviceCIDR`. The default value is `10.43.0.10`.
-
-
-### `serverArgs`
-
-The `serverArgs` field allows you to specify additional arguments to be passed to the K3s server pods.
-
-## Using the cli
-
-You can check the [k3kcli documentation](./cli/k3kcli.md) for the full specs.
-
-### No storage provider:
-
-* Ephemeral Storage:
-
-    ```bash
-    k3kcli cluster create --persistence-type ephemeral my-cluster
-    ```
-
-*Important Notes:*
-
-* Using `--persistence-type ephemeral` will result in data loss if the nodes are restarted.
-
-* It is highly recommended to use `--persistence-type dynamic` with a configured storage class.

-# Architecture
-
-Virtual Clusters are isolated Kubernetes clusters provisioned on a physical cluster. K3k leverages [K3s](https://k3s.io/) as the control plane of the Kubernetes cluster because of its lightweight footprint.
-
-K3k provides two modes of deploying virtual clusters: the "shared" mode (default), and "virtual".
-
-
-## Shared Mode
-
-The default `shared` mode uses a K3s server as control plane with an [agentless servers configuration](https://docs.k3s.io/advanced#running-agentless-servers-experimental). With this option enabled, the servers do not run the kubelet, container runtime, or CNI. The server uses a [Virtual Kubelet](https://virtual-kubelet.io/) provider implementation specific to K3k, which schedules the workloads and other eventually needed resources on the host cluster. This K3k Virtual Kubelet provider handles the reflection of resources and workload execution within the shared host cluster environment.
-
-![Shared Mode](./images/architecture/shared-mode.png)
-
-
-### Networking and Storage
-
-Because of this shared infrastructure, the CNI will be the same one configured in the host cluster. To provide the needed isolation, K3k will leverage Network Policies.
-
-The same goes for the available storage, so the Storage Classes and Volumes are those of the host cluster.
-
-
-### Resource Sharing and Limits
-
-In shared mode, K3k leverages Kubernetes ResourceQuotas and LimitRanges to manage resource sharing and enforce limits.  Since all virtual cluster workloads run within the same namespace on the host cluster, ResourceQuotas are applied to this namespace to limit the total resources consumed by a virtual cluster. LimitRanges are used to set default resource requests and limits for pods, ensuring that workloads have reasonable resource allocations even if they don't explicitly specify them.
-
-Each pod in a virtual cluster is assigned a unique name that incorporates the pod name, namespace, and cluster name. This prevents naming collisions in the shared host cluster namespace.
-
-It's important to understand that ResourceQuotas are applied at the namespace level. This means that all pods within a virtual cluster share the same quota.  While this provides overall limits for the virtual cluster, it also means that resource allocation is dynamic. If one workload isn't using its full resource allocation, other workloads within the *same* virtual cluster can utilize those resources, even if they belong to different deployments or services.
-
-This dynamic sharing can be both a benefit and a challenge.  It allows for efficient resource utilization, but it can also lead to unpredictable performance if workloads have varying resource demands.  Furthermore, this approach makes it difficult to guarantee strict resource isolation between workloads within the same virtual cluster.
-
-GPU resource sharing is an area of ongoing investigation. K3k is actively exploring potential solutions in this area.
-
-
-### Isolation and Security
-
-Isolation between virtual clusters in shared mode relies heavily on Kubernetes Network Policies.  Network Policies define rules that control the network traffic allowed to and from pods.  K3k configures Network Policies to ensure that pods in one virtual cluster cannot communicate with pods in other virtual clusters or with pods in the host cluster itself, providing a strong foundation for network isolation.
-
-While Network Policies offer robust isolation capabilities, it's important to understand their characteristics:
-
-* **CNI Integration:** Network Policies integrate seamlessly with supported CNI plugins.  K3k leverages this integration to enforce network isolation.
-* **Granular Control:** Network Policies provide granular control over network traffic, allowing for fine-tuned security policies.
-* **Scalability:** Network Policies scale well with the number of virtual clusters and applications, ensuring consistent isolation as the environment grows.
-
-K3k also utilizes Kubernetes Pod Security Admission (PSA) to enforce security policies within virtual clusters based on Pod Security Standards (PSS).  PSS define different levels of security for pods, restricting what actions pods can perform.  By configuring PSA to enforce a specific PSS level (e.g., `baseline` or `restricted`) for a virtual cluster, K3k ensures that pods adhere to established security best practices and prevents them from using privileged features or performing potentially dangerous operations.
-
-Key aspects of PSA integration include:
-
-* **Namespace-Level Enforcement:** PSA configuration is applied at the namespace level, providing a consistent security posture for all pods within the virtual cluster.
-* **Standardized Profiles:** PSS offers a set of predefined security profiles aligned with industry best practices, simplifying security configuration and ensuring a baseline level of security.
-
-The shared mode architecture is designed with security in mind.  K3k employs multiple layers of security controls, including Network Policies and PSA, to protect virtual clusters and the host cluster.  While the shared namespace model requires careful configuration and management, these controls provide a robust security foundation for running workloads in a multi-tenant environment.  K3k continuously evaluates and enhances its security mechanisms to address evolving threats and ensure the highest level of protection for its users.
-
-
-## Virtual Mode
-
-The `virtual` mode in K3k deploys fully functional K3s clusters (including both server and agent components) as virtual clusters.  These K3s clusters run as pods within the host cluster.  Each virtual cluster has its own dedicated K3s server and one or more K3s agents acting as worker nodes. This approach provides strong isolation, as each virtual cluster operates independently with its own control plane and worker nodes.  While these virtual clusters run as pods on the host cluster, they function as complete and separate Kubernetes environments.
-
-![Virtual Mode](./images/architecture/virtual-mode.png)
-
-
-### Networking and Storage
-
-Virtual clusters in `virtual` mode each have their own independent networking configuration managed by their respective K3s servers.  Each virtual cluster runs its own CNI plugin, configured within its K3s server, providing complete network isolation from other virtual clusters and the host cluster.  While the virtual cluster networks ultimately operate on top of the host cluster's network infrastructure, the networking configuration and traffic management are entirely separate.
-
-
-### Resource Sharing and Limits
-
-Resource sharing in `virtual` mode is managed by applying resource limits to the pods that make up the virtual cluster (both the K3s server pod and the K3s agent pods).  Each pod is assigned a specific amount of CPU, memory, and other resources.  The workloads running *within* the virtual cluster then utilize these allocated resources.  This means that the virtual cluster as a whole has a defined resource pool determined by the limits on its constituent pods.
-
-This approach provides a clear and direct way to control the resources available to each virtual cluster.  However, it requires careful resource planning to ensure that each virtual cluster has sufficient capacity for its workloads.
-
-
-### Isolation and Security
-
-The `virtual` mode offers strong isolation due to the dedicated K3s clusters deployed for each virtual cluster.  Because each virtual cluster runs its own separate control plane and worker nodes, workloads are effectively isolated from each other and from the host cluster.  This architecture minimizes the risk of one virtual cluster impacting others or the host cluster.
-
-Security in `virtual` mode benefits from the inherent isolation provided by the separate K3s clusters.  However, standard Kubernetes security best practices still apply, and K3k emphasizes a layered security approach.  While the K3s server pods often run with elevated privileges (due to the nature of their function, requiring access to system resources), K3k recommends minimizing these privileges whenever possible and adhering to the principle of least privilege.  This can be achieved by carefully configuring the necessary capabilities instead of relying on full `privileged` mode.  Further information on K3s security best practices can be found in the official K3s documentation: [https://docs.k3s.io/security](https://docs.k3s.io/security) (This link provides general security guidance, including discussions of capabilities and other relevant topics).
-
-Currently security in virtual  mode has a risk of privilege escalation as the server pods run with elevated privileges (due to the nature of their function, requiring access to system resources).
-
-
-## K3k Components
-
-K3k consists of two main components:
-
-* **Controller:** The K3k controller is a core component that runs on the host cluster. It watches for `Cluster` custom resources (CRs) and manages the lifecycle of virtual clusters. When a new `Cluster` CR is created, the controller provisions the necessary resources, including namespaces, K3s server and agent pods, and network configurations, to create the virtual cluster.
-* **CLI:** The K3k CLI provides a command-line interface for interacting with K3k. It allows users to easily create, manage, and access virtual clusters. The CLI simplifies common tasks such as creating `Cluster` CRs, retrieving kubeconfigs for accessing virtual clusters, and performing other management operations.
-
-
-## VirtualClusterPolicy
-
-K3k introduces the VirtualClusterPolicy Custom Resource, a way to set up and apply common configurations and how your virtual clusters operate within the K3k environment.
-
-The primary goal of VCPs is to allow administrators to centrally manage and apply consistent policies. This reduces repetitive configuration, helps meet organizational standards, and enhances the security and operational consistency of virtual clusters managed by K3k.
-
-A VirtualClusterPolicy is bound to one or more Kubernetes Namespaces. Once bound, the rules defined in the VCP apply to all K3k virtual clusters that are running or get created in that Namespace. This allows for flexible policy application, meaning different Namespaces can use their own unique VCPs, while others can share a single VCP for a consistent setup.
-
-Common use cases for administrators leveraging VirtualClusterPolicy include:
-
-- Defining the operational mode (like "shared" or "virtual") for virtual clusters.
-- Setting up resource quotas and limit ranges to effectively manage how much resources virtual clusters and their workloads can use.
-- Enforcing security standards, for example, by configuring Pod Security Admission (PSA) labels for Namespaces.
-
-The K3k controller actively monitors VirtualClusterPolicy resources and the corresponding Namespace bindings. When a VCP is applied or updated, the controller ensures that the defined configurations are enforced on the relevant virtual clusters and their associated resources within the targeted Namespaces.
-
-For a deep dive into what VirtualClusterPolicy can do, along with more examples, check out the [VirtualClusterPolicy Concepts](./virtualclusterpolicy.md) page. For a full list of all the spec fields, see the [API Reference for VirtualClusterPolicy](./crds/crds.md#virtualclusterpolicy).
-
-
-## Comparison and Trade-offs
-
-K3k offers two distinct modes for deploying virtual clusters: `shared` and `virtual`. Each mode has its own strengths and weaknesses, and the best choice depends on the specific needs and priorities of the user. Here's a comparison to help you make an informed decision:
-
-| Feature | Shared Mode | Virtual Mode |
-|---|---|---|
-| **Architecture** | Agentless K3s server with Virtual Kubelet | Full K3s cluster (server and agents) as pods |
-| **Isolation** | Network Policies | Dedicated control plane and worker nodes |
-| **Resource Sharing** | Dynamic, namespace-level ResourceQuotas | Resource limits on virtual cluster pods |
-| **Networking** | Host cluster's CNI | Virtual cluster's own CNI |
-| **Storage** | Host cluster's storage | *Under development* |
-| **Security** | Pod Security Admission (PSA), Network Policies | Inherent isolation, PSA, Network Policies, secure host configuration |
-| **Performance** | Smaller footprint, more efficient due to running directly on the host | Higher overhead due to running full K3s clusters |
-
-**Trade-offs:**
-
-* **Isolation vs. Overhead:** The `shared` mode has lower overhead but weaker isolation, while the `virtual` mode provides stronger isolation but potentially higher overhead due to running full K3s clusters.
-* **Resource Sharing:** The `shared` mode offers dynamic resource sharing within a namespace, which can be efficient but less predictable. The `virtual` mode provides dedicated resources to each virtual cluster, offering more control but requiring careful planning.
-
-**Choosing the right mode:**
-
-* **Choose `shared` mode if:**
-    * You prioritize low overhead and resource efficiency.
-    * You need a simple setup and don't require strong isolation between virtual clusters.
-    * Your workloads don't have strict performance requirements.
-    * Your workloads needs host capacities (GPU)
-* **Choose `virtual` mode if:**
-    * You prioritize strong isolation.
-    * You need dedicated resources and predictable performance for your virtual clusters.
-
-Ultimately, the best choice depends on your specific requirements and priorities. Consider the trade-offs carefully and choose the mode that best aligns with your needs.

-# Development
-
-
-## Prerequisites
-
-To start developing K3k you will need:
-
-- Go
-- Docker
-- Helm
-- A running Kubernetes cluster
-
-
-> [!IMPORTANT]
-> 
-> Virtual clusters in shared mode need to have a configured storage provider, unless the `--persistence-type ephemeral` flag is used.
-> 
-> To install the [`local-path-provisioner`](https://github.com/rancher/local-path-provisioner) and set it as the default storage class you can run:
-> 
-> ```
-> kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/v0.0.34/deploy/local-path-storage.yaml
-> kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
-> ```
-
-
-### TLDR
-
-```shell
-#!/bin/bash
-
-set -euo pipefail
-
-# These environment variables configure the image repository and tag.
-export REPO=ghcr.io/myuser
-export VERSION=dev-$(date -u '+%Y%m%d%H%M')
-
-make
-make push
-make install
-```
-
-### Makefile
-
-To see all the available Make commands you can run `make help`, i.e:
-
-```

-```
-
-### Build
-
-To build the needed binaries (`k3k`, `k3k-kubelet` and the `k3kcli`) and package the images you can simply run `make`.
-
-By default the `rancher` repository will be used, but you can customize this to your registry with the `REPO` env var:
-
-```
-REPO=ghcr.io/userorg make
-```
-
-To customize the tag you can also explicitly set the VERSION:
-
-```
-VERSION=dev-$(date -u '+%Y%m%d%H%M') make
-```
-
-
-### Push
-
-You will need to push the built images to your registry, and you can use the `make push` command to do this.
-
-
-### Install
-
-Once you have your images available you can install K3k with the `make install` command. This will use `helm` to install the release.
-
-
-## Tests
-
-To run the tests you can just run `make test`, or one of the other available "sub-tests" targets (`test-unit`, `test-controller`, `test-e2e`, `test-cli`).
-
-When running the tests the namespaces used are cleaned up. If you want to keep them to debug you can use the `KEEP_NAMESPACES`, i.e.:
-
-```
-KEEP_NAMESPACES=true make test-e2e
-```
-
-The e2e and cli tests run against the cluster configured in your KUBECONFIG environment variable. Running the tests with the `K3K_DOCKER_INSTALL` environment variable set will use `tescontainers` instead:
-
-```
-K3K_DOCKER_INSTALL=true make test-e2e
-```
-
-
-We use [Ginkgo](https://onsi.github.io/ginkgo/), and [`envtest`](https://book.kubebuilder.io/reference/envtest) for testing the controllers.
-
-The required binaries for `envtest` are installed with [`setup-envtest`](https://pkg.go.dev/sigs.k8s.io/controller-runtime/tools/setup-envtest), in the `.envtest` folder.
-
-
-## CRDs and Docs
-
-We are using Kubebuilder and `controller-gen` to build the needed CRDs. To generate the specs you can run `make generate`.
-
-Remember also to update the CRDs documentation running the `make docs` command.
-
-## How to install k3k on k3d
-
-This document provides a guide on how to install k3k on [k3d](https://k3d.io).
-
-### Installing k3d
-
-Since k3d uses docker under the hood, we need to expose the ports on the host that we'll then use for the NodePort in virtual cluster creation.
-
-Create the k3d cluster in the following way:
-
-```bash
-k3d cluster create k3k -p "30000-30010:30000-30010@server:0"
-```
-
-With this syntax ports from 30000 to 30010 will be exposed on the host.
-
-### Install k3k
-
-Install now k3k as usual:
-
-```bash
-helm repo update
-helm install --namespace k3k-system --create-namespace k3k k3k/k3k
-```
-
-### Create a virtual cluster
-
-Once the k3k controller is up and running, create a namespace where to create our first virtual cluster.
-
-```bash
-kubectl create ns k3k-mycluster
-```
-
-Create then the virtual cluster exposing through NodePort one of the ports that we set up in the previous step:
-
-```bash
-cat <<EOF | kubectl apply -f -
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: mycluster
-  namespace: k3k-mycluster
-spec:    
-  expose:
-    nodePort:
-      serverPort: 30001
-EOF
-```
-
-Check when the cluster is ready:
-
-```bash
-kubectl get po -n k3k-mycluster
-```
-
-Last thing to do is to get the kubeconfig to connect to the virtual cluster we've just created:
-
-```bash
-k3kcli kubeconfig generate --name mycluster --namespace k3k-mycluster --kubeconfig-server localhost:30001
-```
-
-
-> [!IMPORTANT]
-> Because of technical limitation is not possible to create virtual clusters in `virtual` mode with K3d, or any other dockerized environment (Kind, Minikube)

-# K3k Air Gap Installation Guide
-
-Applicable K3k modes: `virtual`, `shared`
-
-This guide describes how to deploy **K3k** in an **air-gapped environment**, including the packaging of required images, Helm chart configurations, and cluster creation using a private container registry.
-
----
-
-## 1. Package Required Container Images
-
-### 1.1: Follow K3s Air Gap Preparation
-
-Begin with the official K3s air gap packaging instructions:  
-[K3s Air Gap Installation Docs](https://docs.k3s.io/installation/airgap)
-
-### 1.2: Include K3k-Specific Images
-
-In addition to the K3s images, make sure to include the following in your image bundle:
-
-| Image Names                 | Descriptions                                                    |
-| --------------------------- | --------------------------------------------------------------- |
-| `rancher/k3k:<tag>`         | K3k controller image (replace `<tag>` with the desired version) |
-| `rancher/k3k-kubelet:<tag>` | K3k agent image for shared mode                                 |
-| `rancher/k3s:<tag>`         | K3s server/agent image for virtual clusters                     |
-
-Load these images into your internal (air-gapped) registry.
-
----
-
-## 2. Configure Helm Chart for Air Gap installation
-
-Update the `values.yaml` file in the K3k Helm chart with air gap settings:
-
-```yaml
-controller:
-  imagePullSecrets: [] # Optional
-  image:
-    repository: rancher/k3k
-    tag: ""            # Specify the version tag
-    pullPolicy: ""     # Optional: "IfNotPresent", "Always", etc.
-
-agent:
-  imagePullSecrets: []
-  virtual:
-    image:
-      repository: rancher/k3s
-      pullPolicy: "" # Optional
-  shared:
-    image:
-      repository: rancher/k3k-kubelet
-      tag: ""          # Specify the version tag
-      pullPolicy: ""   # Optional
-
-server:
-  imagePullSecrets: [] # Optional
-  image:
-    repository: rancher/k3s
-    pullPolicy: ""   # Optional
-```
-
-These values enforce the use of internal image repositories for the K3k controller, the agent and the server.
-
-**Note** : All virtual clusters will use automatically those settings. 
-
----
-
-## 3. Enforce Registry in Virtual Clusters
-
-When creating a virtual cluster, use the `--system-default-registry` flag to ensure all system components (e.g., CoreDNS) pull from your internal registry:
-
-```bash
-k3kcli cluster create \
-  --server-args "--system-default-registry=registry.internal.domain" \
-  my-cluster
-```
-
-This flag is passed directly to the K3s server in the virtual cluster, influencing all system workload image pulls.  
-[K3s Server CLI Reference](https://docs.k3s.io/cli/server#k3s-server-cli-help)
-
----
-
-## 4. Specify K3s Version for Virtual Clusters
-
-K3k allows specifying the K3s version used in each virtual cluster:
-
-```bash
-k3kcli cluster create \
-  --k3s-version v1.29.4+k3s1 \
-  my-cluster
-```
-
-- If omitted, the **host cluster’s K3s version** will be used by default, which might not exist if it's not part of the air gap package.

-# How to Choose Between Shared and Virtual Mode
-
-This guide helps you choose the right mode for your virtual cluster: **Shared** or **Virtual**.  
-If you're unsure, start with **Shared mode** — it's the default and fits most common scenarios.
-
----
-
-## Shared Mode (default)
-
-**Best for:**
-- Developers who want to run workloads quickly without managing Kubernetes internals
-- Platform teams that require visibility and control over all workloads
-- Users who need access to host-level resources (e.g., GPUs)
-
-In **Shared mode**, the virtual cluster runs its own K3s server but relies on the host to execute workloads. The virtual kubelet syncs resources, enabling lightweight, fast provisioning with support for cluster resource isolation. More details on the [architecture](./../architecture.md#shared-mode). 
-
----
-
-### Use Cases by Persona
-
-#### 👩‍💻 Developer  
-*"I’m building a web app that should be exposed outside the virtual cluster."*  
-→ Use **Shared mode**. It allows you to [expose](./expose-workloads.md) your application.
-
-#### 👩‍🔬 Data Scientist:
-*“I need to run Jupyter notebooks that leverage the cluster's GPU.”*  
-→ Use **Shared mode**. It gives access to physical devices while keeping overhead low.
-
-#### 🧑‍💼 Platform Admin  
-*"I want to monitor and secure all tenant workloads from a central location."*  
-→ Use **Shared mode**. Host-level agents (e.g., observability, policy enforcement) work across all virtual clusters.
-
-#### 🔒 Security Engineer  
-*"I need to enforce security policies like network policies or runtime scanning across all workloads."*  
-→ Use **Shared mode**. The platform can enforce policies globally without tenant bypass.
-
-*"I need to test a new admission controller or policy engine."*  
-→ Use **Shared mode**, if it's scoped to your virtual cluster. You can run tools like Kubewarden without affecting the host.  
-
-#### 🔁 CI/CD Engineer  
-*"I want to spin up disposable virtual clusters per pipeline run, fast and with low resource cost."*  
-→ Use **Shared mode**. It's quick to provision and ideal for short-lived, namespace-scoped environments.
-
----
-
-## Virtual Mode
-
-**Best for:**
-- Advanced users who need full Kubernetes isolation
-- Developers testing experimental or cluster-wide features
-- Use cases requiring control over the entire Kubernetes control plane
-
-In **Virtual mode**, the virtual cluster runs its own isolated Kubernetes control plane. It supports different CNIs, and API configurations — ideal for deep experimentation or advanced workloads. More details on the [architecture](./../architecture.md#virtual-mode). 
-
----
-
-### Use Cases by Persona
-
-#### 👩‍💻 Developer  
-*"I need to test a new Kubernetes feature gate that’s disabled in the host cluster."*  
-→ Use **Virtual mode**. You can configure your own control plane flags and API features.
-
-#### 🧑‍💼 Platform Admin  
-*"We’re testing upgrades across Kubernetes versions, including new API behaviors."*
-→ Use Virtual mode. You can run different Kubernetes versions and safely validate upgrade paths.
-
-#### 🌐 Network Engineer  
-*"I’m evaluating a new CNI that needs full control of the cluster’s networking."*  
-→ Use **Virtual mode**. You can run a separate CNI stack without affecting the host or other tenants.
-
-#### 🔒 Security Engineer  
-*"I’m testing a new admission controller and policy engine before rolling it out cluster-wide."*  
-→ Use **Virtual mode**, if you need to test cluster-wide policies, custom admission flow, or advanced extensions with full control.

-# How to: Create a Virtual Cluster
-
-This guide walks through the various ways to create and manage virtual clusters in K3K. We'll cover common use cases using both the **Custom Resource Definitions (CRDs)** and the **K3K CLI**, so you can choose the method that fits your workflow.
-
-> 📘 For full reference:  
-> - [CRD Reference Documentation](../crds/crds.md)  
-> - [CLI Reference Documentation](../cli/k3kcli.md)  
-> - [Full example](../advanced-usage.md)
-
-> [!NOTE]
-> 🚧 Some features are currently only available via the CRD interface. CLI support may be added in the future.
-
----
-
-## Use Case: Create and Expose a Basic Virtual Cluster
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-ingress
-spec:
-  tlsSANs:
-    - my-cluster.example.com
-  expose:
-    ingress:
-      ingressClassName: nginx
-      annotations:
-        nginx.ingress.kubernetes.io/ssl-passthrough: "true"
-        nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
-        nginx.ingress.kubernetes.io/ssl-redirect: "HTTPS"
-```
-
-This will create a virtual cluster in `shared` mode and expose it via an ingress with the specified hostname.
-
-### CLI Method
-
-*No CLI method available yet*
-
----
-
-## Use Case: Create a Virtual Cluster with Persistent Storage (**Default**)
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-persistent
-spec:
-  persistence:
-    type: dynamic
-    storageClassName: local-path
-    storageRequestSize: 30Gi
-```
-
-This ensures that the virtual cluster stores its state persistently with a 30Gi volume.  
-If `storageClassName` is not set it will default to the default StorageClass.  
-If `storageRequestSize` is not set it will request a 1Gi volume by default.  
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --persistence-type dynamic \
-  --storage-class-name local-path \
-  k3kcluster-persistent
-```
-
-> [!NOTE]
-> The `k3kcli` does not support configuring the `storageRequestSize` yet.
-
----
-
-## Use Case: Create a Highly Available Virtual Cluster in `shared` mode
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-ha
-spec:
-  servers: 3
-```
-
-This will create a virtual cluster with 3 servers and a default 1Gi volume for persistence.  
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --servers 3 \
-  k3kcluster-ha
-```
-
----
-
-## Use Case: Create a Highly Available Virtual Cluster in `virtual` mode
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-virtual
-spec:
-  mode: virtual
-  servers: 3
-  agents: 3
-```
-
-This will create a virtual cluster with 3 servers and 3 agents and a default 1Gi volume for persistence.  
-> [!NOTE]
-> Agents only exist for `virtual` mode.
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --agents 3 \
-  --servers 3 \
-  --mode virtual \
-  k3kcluster-virtual
-```
-
----
-
-## Use Case: Create an Ephemeral Virtual Cluster
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-ephemeral
-spec:
-  persistence:
-    type: ephemeral
-```
-
-This will create an ephemeral virtual cluster with no persistence and a single server.  
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --persistence-type ephemeral \
-  k3kcluster-ephemeral
-```
-
----
-
-## Use Case: Create a Virtual Cluster with a Custom Kubernetes Version
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-custom-k8s
-spec:
-  version: "v1.33.1-k3s1"
-```
-
-This sets the virtual cluster's Kubernetes version explicitly.  
-> [!NOTE]
-> Only [K3s](https://k3s.io) distributions are supported. You can find compatible versions on the K3s GitHub [release page](https://github.com/k3s-io/k3s/releases).
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --version v1.33.1-k3s1 \
-  k3kcluster-custom-k8s
-```
-
----
-
-## Use Case: Create a Virtual Cluster with Custom Resource Limits
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-resourced
-spec:
-  mode: virtual
-  serverLimit:
-    cpu: "1"
-    memory: "2Gi"
-  workerLimit:
-    cpu: "1"
-    memory: "2Gi"
-```
-
-This configures the CPU and memory limit for the virtual cluster.
-
-### CLI Method
-
-*No CLI method available yet*
-
----
-
-## Use Case: Create a Virtual Cluster on specific host nodes
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-node-placed
-spec:
-  nodeSelector:
-    disktype: ssd
-```
-
-This places the virtual cluster on nodes with the label `disktype: ssd`.  
-> [!NOTE]
-> In `shared` mode workloads are also scheduled on the selected nodes
-
-### CLI Method
-
-*No CLI method available yet*
-
----
-
-## Use Case: Create a Virtual Cluster with a Rancher Host Cluster Kubeconfig
-
-When using a `kubeconfig` generated with Rancher, you need to specify with the CLI the desired host for the virtual cluster `kubeconfig`.  
-By default, `k3kcli` uses the current host `kubeconfig` to determine the target cluster.
-
-### CRD Method
-
-*Not applicable*
-
-### CLI Method
-
-```sh
-k3kcli cluster create \
-  --kubeconfig-server https://abc.xyz \
-  k3kcluster-host-rancher
-```
-
----
-
-## Use Case: Create a Virtual Cluster Behind an HTTP Proxy
-
-### CRD Method
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: Cluster
-metadata:
-  name: k3kcluster-http-proxy
-spec:
-  serverEnvs:
-    - name: HTTP_PROXY
-      value: "http://abc.xyz"
-  agentEnvs:
-    - name: HTTP_PROXY
-      value: "http://abc.xyz"
-```
-
-This configures an HTTP proxy for both servers and agents in the virtual cluster.  
-> [!NOTE]  
-> This can be leveraged to pass **any custom environment variables** to the servers and agents — not just proxy settings.
-
-### CLI Method
-
-```sh
-k3kcli cluster create  \
-  --server-envs HTTP_PROXY=http://abc.xyz \
-  --agent-envs HTTP_PROXY=http://abc.xyz \
-  k3kcluster-http-proxy
-```
-
----
-
-## How to: Connect to a Virtual Cluster
-
-Once the virtual cluster is running, you can connect to it using the CLI:
-
-### CLI Method
-
-```sh
-k3kcli kubeconfig generate --namespace k3k-mycluster --name mycluster 
-export KUBECONFIG=$PWD/mycluster-kubeconfig.yaml
-kubectl get nodes
-```
-
-This command generates a `kubeconfig` file, which you can use to access your virtual cluster via `kubectl`.

-# How-to: Expose Workloads Outside the Virtual Cluster
-
-This guide explains how to expose workloads running in k3k-managed virtual clusters to external networks. Behavior varies depending on the operating mode of the virtual cluster.
-
-## Virtual Mode
-
-> [!CAUTION]
-> **Not Supported**  
-> In *virtual mode*, direct external exposure of workloads is **not available**.  
-> This mode is designed for strong isolation and does not expose the virtual cluster's network directly.
-
-## Shared Mode
-
-In *shared mode*, workloads can be exposed to the external network using standard Kubernetes service types or an ingress controller, depending on your requirements.
-
-> [!NOTE]
-> *`Services`* are always synced from the virtual cluster to the host cluster following the same principle described [here](../architecture.md#shared-mode) for pods. 
-
-### Option 1: Use `NodePort` or `LoadBalancer`
-
-To expose a service such as a web application outside the host cluster:
-
-- **`NodePort`**:  
-  Exposes the service on a static port on each node’s IP.  
-  Access the service at `http://<NodeIP>:<NodePort>`.
-
-- **`LoadBalancer`**:  
-  Provisions an external load balancer (if supported by the environment) and exposes the service via the load balancer’s IP.
-
-> **Note**  
-> The `LoadBalancer` IP is currently not reflected back to the virtual cluster service.  
-> [k3k issue #365](https://github.com/rancher/k3k/issues/365)
-
-### Option 2: Use `ClusterIP` for Internal Communication
-
-If the workload should only be accessible to other services or pods *within* the host cluster:
-
-- Use the `ClusterIP` service type.  
-  This exposes the service on an internal IP, only reachable inside the host cluster.
-
-### Option 3: Use Ingress for HTTP/HTTPS Routing
-
-For more advanced routing (e.g., hostname- or path-based routing), deploy an **Ingress controller** in the virtual cluster, and expose it via `NodePort` or `LoadBalancer`.
-
-This allows you to:
-
-- Define Ingress resources in the virtual cluster.
-- Route external traffic to services within the virtual cluster.
-
->**Note**  
-> Support for using the host cluster's Ingress controller from a virtual cluster is being tracked in

-# Troubleshooting
-
-This guide walks through common troubleshooting steps for working with K3K virtual clusters.

----
-
-## `too many open files` error
-
-The `k3k-kubelet` or `k3kcluster-server-` run into the following issue:  
-
-```sh
-E0604 13:14:53.369369       1 leaderelection.go:336] error initially creating leader election record: Post "https://k3k-http-proxy-k3kcluster-service/apis/coordination.k8s.io/v1/namespaces/kube-system/leases": context canceled

-```
-
-This typically indicates a low limit on inotify watchers or file descriptors on the host system.
-
-To increase the inotify limits connect to the host nodes and run:
-
-```sh
-sudo sysctl -w fs.inotify.max_user_watches=2099999999
-sudo sysctl -w fs.inotify.max_user_instances=2099999999
-sudo sysctl -w fs.inotify.max_queued_events=2099999999
-```
-
-You can persist these settings by adding them to `/etc/sysctl.conf`:
-
-```sh
-fs.inotify.max_user_watches=2099999999
-fs.inotify.max_user_instances=2099999999
-fs.inotify.max_queued_events=2099999999
-```
-
-Apply the changes:
-

-## Inspect Controller Logs for Failure Diagnosis
-
-To view logs for a failed virtual cluster:
-
-```sh
-kubectl logs -n k3k-system -l app.kubernetes.io/name=k3k
-```
-
-This retrieves logs from K3k controller components.

-## Inspect Cluster Logs for Failure Diagnosis
-
-To view logs for a failed virtual cluster:
-
-```sh
-kubectl logs -n <cluster_namespace> -l cluster=<cluster_name>

----
-
-## Virtual Cluster Not Starting or Stuck in Pending
-
-Some of the most common causes are related to missing prerequisites or wrong configuration.
-
-### Storage class not available
-
-When creating a Virtual Cluster with `dynamic` persistence, a PVC is needed. You can check if the PVC was claimed but not bound with `kubectl get pvc -n <cluster_namespace>`. If you see a pending PVC you probably don't have a default storage class defined, or you have specified a wrong one.
-
-#### Example with wrong storage class
-
-The `pvc` is pending:
-
-```bash
-kubectl get pvc -n k3k-test-storage
-NAME                                         STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS    VOLUMEATTRIBUTESCLASS   AGE
-varlibrancherk3s-k3k-test-storage-server-0   Pending                                      not-available   <unset>                 4s
-```
-
-The `server` is pending:
-
-```bash
-kubectl get po -n k3k-test-storage
-NAME                             READY   STATUS    RESTARTS   AGE
-k3k-test-storage-kubelet-j4zn5   1/1     Running   0          54s
-k3k-test-storage-server-0        0/1     Pending   0          54s
-```
-
-To fix this you should use a valid storage class, you can list existing storage class using:
-
-```bash
-kubectl get storageclasses.storage.k8s.io
-NAME                   PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
-local-path (default)   rancher.io/local-path   Delete          WaitForFirstConsumer   false                  3d6h
-```
-
-### Wrong node selector
-
-When creating a Virtual Cluster with `defaultNodeSelector`, if the selector is not valid all pods will be pending.
-
-#### Example
-
-The `server` is pending:
-
-```bash
-kubectl get po
-NAME                                  READY   STATUS    RESTARTS   AGE
-k3k-k3kcluster-node-placed-server-0   0/1     Pending   0          58s
-```
-
-The description of the pod provide the reason:
-
-```bash
-kubectl describe po k3k-k3kcluster-node-placed-server-0
-...
-Events:
-  Type     Reason            Age   From               Message
-  ----     ------            ----  ----               -------
-  Warning  FailedScheduling  84s   default-scheduler  0/1 nodes are available: 1 node(s) didn't match Pod's node affinity/selector. preemption: 0/1 nodes are available: 1 Preemption is not helpful for scheduling.
-```
-
-To fix this you should use a valid node affinity/selector.
-
-### Image pull issues (airgapped setup)
-
-When creating a Virtual Cluster in air-gapped environment, images need to be available in the configured registry. You can check for `ImagePullBackOff` status when getting the pods in the virtual cluster namespace.
-
-#### Example
-
-The `server` is failing:
-
-```bash
-kubectl get po -n k3k-test-registry
-NAME                             READY   STATUS          RESTARTS       AGE
-k3k-test-registry-kubelet-r4zh5   1/1     Running            0          54s
-k3k-test-registry-server-0        0/1     ImagePullBackOff   0          54s
-```
-
-To fix this make sure the failing image is available. You can describe the failing pod to get more details.

-# VirtualClusterPolicy
-
-The VirtualClusterPolicy Custom Resource in K3k provides a way to define and enforce consistent configurations, security settings, and resource management rules for your virtual clusters and the Namespaces they operate within.
-
-By using VCPs, administrators can centrally manage these aspects, reducing manual configuration, ensuring alignment with organizational standards, and enhancing the overall security and operational consistency of the K3k environment.
-
-## Core Concepts
-
-### What is a VirtualClusterPolicy?
-
-A `VirtualClusterPolicy` is a cluster-scoped Kubernetes Custom Resource that specifies a set of rules and configurations. These policies are then applied to K3k virtual clusters (`Cluster` resources) operating within Kubernetes Namespaces that are explicitly bound to a VCP.
-
-### Binding a Policy to a Namespace
-
-To apply a `VirtualClusterPolicy` to one or more Namespaces (and thus to all K3k `Cluster` resources within those Namespaces), you need to label the desired Namespace(s). Add the following label to your Namespace metadata:

-`policy.k3k.io/policy-name: <YOUR_POLICY_NAME>`
-
-**Example: Labeling a Namespace**
-
-```yaml
-apiVersion: v1
-kind: Namespace
-metadata:
-  name: my-app-namespace
-  labels:
-    policy.k3k.io/policy-name: "standard-dev-policy"
-```
-
-In this example, `my-app-namespace` will adhere to the rules defined in the `VirtualClusterPolicy` named `standard-dev-policy`. Multiple Namespaces can be bound to the same policy for uniform configuration, or different Namespaces can be bound to distinct policies.
-
-It's also important to note what happens when a Namespace's policy binding changes. If a Namespace is unbound from a VirtualClusterPolicy (by removing the policy.k3k.io/policy-name label), K3k will clean up and remove the resources (such as ResourceQuotas, LimitRanges, and managed Namespace labels) that were originally applied by that policy. Similarly, if the label is changed to bind the Namespace to a new VirtualClusterPolicy, K3k will first remove the resources associated with the old policy before applying the configurations from the new one, ensuring a clean transition.
-
-### Default Policy Values
-
-If you create a `VirtualClusterPolicy` without specifying any `spec` fields (e.g., using `k3kcli policy create my-default-policy`), it will be created with default settings. Currently, this includes `spec.allowedMode` being set to `"shared"`.
-
-```yaml
-# Example of a minimal VCP (after creation with defaults)
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: my-default-policy
-spec:
-  allowedMode: shared
-```
-
-## Key Capabilities & Examples
-
-A `VirtualClusterPolicy` can configure several aspects of the Namespaces it's bound to and the virtual clusters operating within them.
-
-### 1. Restricting Allowed Virtual Cluster Modes (`AllowedMode`)
-
-You can restrict the `mode` (e.g., "shared" or "virtual") in which K3k `Cluster` resources can be provisioned within bound Namespaces. If a `Cluster` is created in a bound Namespace with a mode not allowed in `allowedMode`, its creation might proceed but an error should be reported in the `Cluster` resource's status.
-
-**Example:** Allow only "shared" mode clusters.
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: shared-only-policy
-spec:
-  allowedModeTypes:
-  - shared
-```
-
-You can also specify this using the CLI: `k3kcli policy create --mode shared shared-only-policy` (or `--mode virtual`).
-
-### 2. Defining Resource Quotas (`quota`)
-
-You can define resource consumption limits for bound Namespaces by specifying a `ResourceQuota`. K3k will create a `ResourceQuota` object in each bound Namespace with the provided specifications.
-
-**Example:** Set CPU, memory, and pod limits.
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: quota-policy
-spec:
-  quota:
-    hard:
-      cpu: "10"
-      memory: "20Gi"
-      pods: "10"
-```
-
-### 3. Setting Limit Ranges (`limit`)
-
-You can define default resource requests/limits and min/max constraints for containers running in bound Namespaces by specifying a `LimitRange`. K3k will create a `LimitRange` object in each bound Namespace.
-
-**Example:** Define default CPU requests/limits and min/max CPU.
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: limit-policy
-spec:
-  limit:
-    limits:
-    - default:
-        cpu: "500m"
-      defaultRequest:
-        cpu: "500m"
-      max:
-        cpu: "1"
-      min:
-        cpu: "100m"
-      type: Container
-```
-
-### 4. Managing Network Isolation (`disableNetworkPolicy`)
-
-By default, K3k creates a `NetworkPolicy` in bound Namespaces to provide network isolation for virtual clusters (especially in shared mode). You can disable the creation of this default policy.
-
-**Example:** Disable the default NetworkPolicy.
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: no-default-netpol-policy
-spec:
-  disableNetworkPolicy: true
-```
-
-### 5. Enforcing Pod Security Admission (`podSecurityAdmissionLevel`)
-
-You can enforce Pod Security Standards (PSS) by specifying a Pod Security Admission (PSA) level. K3k will apply the corresponding PSA labels to each bound Namespace. The allowed values are `privileged`, `baseline`, `restricted`, and this will add labels like `pod-security.kubernetes.io/enforce: <level>` to the bound Namespace.
-
-**Example:** Enforce the "baseline" PSS level.
-
-```yaml
-apiVersion: k3k.io/v1beta1
-kind: VirtualClusterPolicy
-metadata:
-  name: baseline-psa-policy
-spec:
-  podSecurityAdmissionLevel: baseline
-```
-
-## Further Reading
-
-* For a complete reference of all `VirtualClusterPolicy` spec fields, see the [API Reference for VirtualClusterPolicy](./crds/crds.md#virtualclusterpolicy).
-* To understand how VCPs fit into the overall K3k system, see the [Architecture](./architecture.md) document.
