- For more info: [RKE2 Docs](https://docs.rke2.io/)

## Configure Kubeconfig on Windows 11

1. **Download Kubeconfig File**

    - Copy `/etc/rancher/rke2/rke2.yaml` from the master node to your Windows machine (e.g., using WinSCP or `scp`):

      ```powershell
      scp user@192.168.1.10:/etc/rancher/rke2/rke2.yaml C:\Users\<YourUser>\.kube\config
      ```

2. **Edit Kubeconfig File**

    - Open `C:\Users\<YourUser>\.kube\config` in a text editor.
    - Change the `server:` address from `localhost` to the master node IP, e.g.:
      ```
      server: https://192.168.1.10:6443
      ```

3. **Install kubectl**

    - Download [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/) and add it to your PATH.

    - Verify installation:
      ```powershell
      kubectl version --client
      kubectl get nodes
      ```

4. **Install Helm**

    - Download [Helm](https://helm.sh/docs/intro/install/#from-script) for Windows.
    - Extract and add `helm.exe` to your PATH.
    - Verify installation:
      ```powershell
      helm version
      ```

5. **Test Connectivity**

    - Run:
      ```powershell
      kubectl get pods --all-namespaces
      helm list -A
      ```

**Tip:** Ensure your Windows machine can reach the master node IP and required ports are open.
