Creating new RG with name MC_RG_XXXXXXXX

Good things: Cluster getting created by using existing Vnet, subnet, cluster linked with existing RG but its creating network security Group and DNS Zones with new RG. Any idea?

Answer 1

This is an automatic resource group created to house the cluster https://docs.microsoft.com/en-us/azure/aks/faq#why-are-two-resource-groups-created-with-aks , there is an option in preview to specify the name of this resource group using Azure CLI and within an ARM template https://docs.microsoft.com/en-us/azure/aks/faq#can-i-provide-my-own-name-for-the-aks-node-resource-group.

I'm not sure how this will map in Terraform though.
