🐞 Problem

Add examples for AKS using version = "~> 2.0"

🎯 Goal

Improve examples with modern version of azurerm provider

💡 Possible solutions

Change agent_pool_profile by default_node_pool and linux_profile

in README:

kubectl create clusterrolebinding kubernetes-dashboard --clusterrole=cluster-admin --serviceaccount=kube-system:kubernetes-dashboard

should be:

kubectl create clusterrolebinding kubernetes-dashboard --clusterrole=cluster-admin --serviceaccount=kube-system:kubernetes-dashboard --user=clusterUser

Warning: Version constraints inside provider configuration blocks are deprecated

on aks-cluster.tf line 4, in provider "azurerm":
4: version = "~> 2.0"

Terraform 0.13 and earlier allowed provider version constraints inside the
provider configuration block, but that is now deprecated and will be removed
in a future version of Terraform. To silence this warning, move the provider
version constraint into the required_providers block.

Repo needs an update as the add-on dashboard used in the example is no longer supported with K8S V >=1.19.0.

before you can launch the k8 dashboard, you need to enable the kube-dashboard in azure:

az aks enable-addons --addons kube-dashboard --resource-group $(terraform output resource_group_name) --name $(terraform output kubernetes_cluster_name)
