Deploying AKS Cluster (using Azure CLI):

export AKS_NAME=[enter_AKSCluster_name]

(if needed: az group create --name [enter_ResourceGroup] --location eastus)

az aks create \
	--resource-group $RESOURCE_GROUP_NAME \
	--name $AKS_NAME \
	--os-sku Ubuntu \
	--enable-managed-identity \
	--node-count 1 \
	--enable-addons monitoring \

	--enable-cluster-autoscaler \
	--max-count 5 \
	--min-count 1 \
