 | vnet_address_space | Address space for created vnet | string | "192.168.0.0/16" | This variable is ignored when vnet_name is set (AKA bring your own vnet). |
 | subnets | Subnets to be created and their settings | map(object) | *check below* | This variable is ignored when subnet_names is set (AKA bring your own subnets). All defined subnets must exist within the vnet address space. |
 | cluster_egress_type | The outbound (egress) routing method to be used for this Kubernetes Cluster | string | "loadBalancer" | Possible values: <ul><li>`loadBalancer`<li>`userDefinedRouting`</ul> By default, AKS will create and use a [loadbalancer](https://docs.microsoft.com/en-us/azure/aks/load-balancer-standard) for outgoing connections.<p>Set to `userDefinedRouting` when using your own network [egress](https://docs.microsoft.com/en-us/azure/aks/egress-outboundtype).|
-| aks_network_plugin | Network plugin to use for networking. Currently supported values are `azure` and `kubenet`| string | `kubenet`| For details see Azure's documentation on: [configure kubenet](https://docs.microsoft.com/en-us/azure/aks/configure-kubenet), [Configure Azure CNI](https://learn.microsoft.com/en-us/azure/aks/configure-azure-cni).<br>**Note**: To support Azure CNI your Subnet must be large enough to accommodate the nodes, pods, and all Kubernetes and Azure resources that might be provisioned in your cluster.<br>To calculate the minimum subnet size including an additional node for upgrade operations use formula: `(number of nodes + 1) + ((number of nodes + 1) * maximum pods per node that you configure)` <br>Example for a 5 node cluster: `(5) + (5 * 110) = 555 (/22 or larger)`|
-| aks_network_policy | Sets up network policy to be used with Azure CNI. Network policy allows to control the traffic flow between pods. Currently supported values are `calico` and `azure`.| string | null | Network policy `azure` is only supported for `aks_network_plugin = azure` and network policy `calico` is supported for both `aks_network_plugin` values `azure` and `kubenet`. |
-| aks_network_plugin_mode | Specifies the network plugin mode used for building the Kubernetes network. Possible value is `overlay`.| string | null | When `aks_network_plugin_mode` is set to `overlay` , the `aks_network_plugin` field can only be set to `azure`. For details see Azure's documentation on: [Configure Azure CNI Overlay networking](https://learn.microsoft.com/en-us/azure/aks/azure-cni-overlay).|
