When you deploy on Azure using terraform you may encounter the below error.
The subscription is not registered to use namespace ‘Microsoft.ContainerService’. See https://aka.ms/rps-not-found for how to register subscriptions.
In order to resolve issue you should go inside azure portal and under your subscription you should navigate into Resource Providers. Then you should search for the specific provider that is not registered (in my example in was ContainerService) and click register.
When you press register you will see that the provider is going to be in Registering state.
Finally the deployment will succeed after the above change.
