<p>I have created an instance of Azure Kubernetes Service (AKS) and have discovered that apart from the resource group I created the AKS instance in, one more resource group is created for me.</p>
<p>Eg:</p>
<p>My AKS Resource Group: Production_MyAKSInstance
Additional Resource Group: MC_MyResourceGroup-Production_MyAKSInstance_westeurope</p>
<p>Is there a way to rename the Additional Resource Group something like Production_MyAKSInstance_Supportive?</p>

<p>You can't rename it however you can specify a name when you create the cluster.</p>

<blockquote>
<p>By default, AKS will name the node resource group
MC_resourcegroupname_clustername_location, but you can also provide
your own name.</p>
<p>To specify your own resource group name, install the aks-preview Azure
CLI extension version 0.3.2 or later. When you create an AKS cluster
by using the az aks create command, use the --node-resource-group
parameter and specify a name for the resource group. If you use an
Azure Resource Manager template to deploy an AKS cluster, you can
define the resource group name by using the nodeResourceGroup
property.</p>
<p>The secondary resource group is automatically created by the Azure
resource provider in your own subscription. You can specify a custom
resource group name only when you're creating the cluster. As you work
with the node resource group, keep in mind that you cannot:</p>
<p>Specify an existing resource group for the node resource group.
Specify a different subscription for the node resource group. Change
the node resource group name after the cluster has been created.
Specify names for the managed resources within the node resource
group. Modify or delete Azure-created tags of managed resources within
the node resource group.</p>
