+> [!TIP]
+> To use kubectl with a previously deployed cluster on Azure Kubernetes Service (AKS), you must set the cluster context with the following Azure CLI command:
+>
+>    ```azurecli
+>    az aks get-credentials --name <aks_cluster_name> --resource-group <azure_resource_group_name>
+>    ```
 
 <sup>2</sup> You must be using Azure CLI version 2.0.4 or later. Run `az --version` to find the version if needed.
