# Entando 6 Azure Kubernetes Installation Instructions
- Azure account
- Note: If you're using an Azure free account, you may need to upgrade your account first to enable pay-as-you-go billing. The Azure free account default quota includes just 1-4 vCPU which is not sufficient for this tutorial. There may be a delay before the quotas are updated when you upgrade your account.
- If you're not using Azure Cloud Shell:
- Azure command line tool
- Helm2 client
The steps below walk you through installing the Entando platform in an Azure Kubernetes Services (AKS) cluster. Generally the steps are:
- Create an AKS cluster with 5 nodes (to allow expansion for microservices)
- Install nginx as an ingress controller in the cluster
- Install Entando
If you're already comfortable setting up an AKS cluster and installing nginx then you may be able to skip to setting up Entando.
# Cluster Setup
# Setup and Connect to the Cluster
- Login to Azure (https://portal.azure.com/ (opens new window))
- Select the

Kubernetes cluster. You'll start with the
- Select a
Resource groupor create one with the
Create newlink if it you don’t have one, e.g.
- Enter a name of your choice in Kubernetes cluster name, e.g.
- Pick your
Regionif it wasn't automatically selected for you.
- In the
Availability zonesdropdown pick one and only one availability zone
- Generally, you could pick more than one but it will result in a failure in a quickstart environment. If you chose more than one availability zone you will have to provision storage, manage node affinity, and ensure correct network configuration to ensure your application deploys. We recommend only doing this for production clusters.
- Keep the default
Node size, e.g.
Standard DS2 v2
- Change the

- You can pick a

- Note: There are many other configuration options available for an AKS cluster. Generally, you can change these based on your experience and comfort level with the AKS platform. Entando uses base Kubernetes APIs so as long as you follow the Entando configuration instructions below you can tune your cluster infrastructure to meet your goals
- Wait for your cluster to initialize.
- This may take a few minutes
# Deploy NGINX Ingress Controller
- Navigate to your cluster by clicking
Go to Resourcefrom the results page or by the top navigation
Home - Kubernetes serviceand clicking on your cluster.
- Run the first two commands (e.g.
az account set...and
az aks get-credentials...to connect to your cluster. This should only be needed the first time you run the Azure Cloud Shell.
- The Cloud Shell times out after 20 minutes of inactivity.
- The following instructions assume you'll use the Azure Cloud Shell but you can also run the commands in a local environment if you have
- Deploy nginx with the commands below. See nginx instructions (opens new window) for more details.
kubectl create namespace ingress-basic
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx helm repo add stable https://kubernetes-charts.storage.googleapis.com/ helm repo update
helm install nginx-ingress ingress-nginx/ingress-nginx \ --namespace ingress-basic \ --set controller.replicaCount=2 \ --set controller.nodeSelector."beta\.kubernetes\.io/os"=linux \ --set defaultBackend.nodeSelector."beta\.kubernetes\.io/os"=linux
- Get the external IP address for your ingress controller. Record the value of EXTERNAL-IP for
nginx-ingress-controllerfrom the command below.
kubectl get service -n ingress-basic
# Verify the NGINX Ingress Install
We recommend setting up a test application so you can easily verify the ingress is working in your cluster. See this page for those steps. You can use either Azure Cloud Shell or your local
# Install the Entando Custom Resource Definitions (CRDs)
Once per cluster you need to deploy the
Entando Custom Resources.
- Download the Custom Resource Definitions (CRDs) and deploy them
kubectl apply -n entando -f https://raw.githubusercontent.com/entando/entando-releases/v6.3.2/dist/ge-1-1-6/namespace-scoped-deployment/cluster-resources.yaml
- Install namespace scoped resources
kubectl apply -n entando -f https://raw.githubusercontent.com/entando/entando-releases/v6.3.2/dist/ge-1-1-6/namespace-scoped-deployment/orig/namespace-resources.yaml
# Deploy Your Entando Application
You can now deploy your application to Azure Kubernetes Service.
- Download and unpack the entando-helm-quickstart:
curl -sfL https://github.com/entando-k8s/entando-helm-quickstart/archive/v6.3.2.tar.gz | tar xvz
- See the included README file for more information on subsequent steps.
- Change into the new directory
In values.yaml in the root folder set
entando.default.routing.suffixto the EXTERNAL-IP of your ingress controller and add nip.io to the end
- For example:
- For example:
Create the Entando namespace:
kubectl create namespace entando
- Run helm to generate the template file
helm template quickstart ./ > my-aks-app.yaml
- Deploy Entando via
kubectl create -f my-aks-app.yaml
- Watch Entando startup. The application will be available when the
quickstart-composite-app-deployerpod has a status of completed
kubectl get pods -n entando --watch
- Check for the Entando ingresses using
kubectl describe ingress -n entando
- Access your app on the url for the ingress of the app builder, e.g.
# Appendix A - Troubleshooting
If you get an error like:
0/5 nodes are available: 5 node(s) had volume node affinity conflict. or if your deployment hangs in a situation like this from
kubectl get pods -n entando

Double check your availability zones. By default an Azure cluster will include nodes from multiple zones but it will not provision storage for all of those nodes so you can't deploy your application.
You can confirm this error in the AKS console as well:
- In your cluster select
Workloadsin the left nav
- Click on the deployment for your server application. This is
- Click on the deployment name inside that application. There will be one
- Click on the tab labeled
- If you see an error that says
0/5 nodes are available: 5 node(s) had volume node affinity conflict.Then you need to reconfigure your cluster to have nodes in one zone or work with your Azure operations team to provision storage to match node affinity.
