A Kubernetes cluster is divided into two components:
To run your applications and supporting services, you need a Kubernetes node.
An AKS cluster has one or more nodes, which is an Azure virtual machine (VM) that runs the Kubernetes node components and container runtime.

# install kubectl
az aks install-cli
# download credentials and configurs Kubernetes CLI to use them
az aks get-credentials --resource-group myResourceGroup --name myAKSCluster
# verify the connection
kubectl get nodes
# Deploy the application using the kubectl apply
kubectl apply -f app.yaml
