az aks create --resource-group <rg_name> --name <cluster_name> --node-count 1 --enable-addons monitoring,http_application_routing --generate-ssh-keys --service-principal <appId> --client-secret <password>

In particular, the addons enabled here are

• monitoring to enable the collection of logs in Azure Monitor
• http_application-routing creates an ingress controller and an external DNS controller in order to make application deployed in the cluser easy to access

Install kubectl locally

az aks install-cli

az aks get-credentials --resource-group <rg_name> --name <cluster_name>

To test cluster access

kubectl cluster-info

Create RBAC role for helm

kubectl create -f https://raw.githubusercontent.com/Azure/helm-charts/master/docs/prerequisities/helm-rbac-config.yaml

Initialize helm server in the cluster

helm init --service-account tiller

Check Helm installation

kubectl get pod --all-namespaces

Enable Kubenernetes dashboard for RBAC enabled cluster

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

Create local tunnel on localhost to access the remote cluster dashboard

az aks browse --resource-group <rg_name> --name <cluster_name>

Create a new namespace for the applications deployment

kubectl create namespace <namespace_name>
