Deploy the ofbiz helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the Apache OFBiz Helm chart on Azure Kubernetes Service (AKS), you need to follow several steps. First, you need to create an AKS cluster, and then you need to install the Helm CLI on your local machine. After that, you can add the Helm chart repository for OFBiz, install the OFBiz chart, and finally, verify that the deployment was successful.

Here's how you can achieve this using Pulumi with TypeScript:

Create an AKS cluster: We will use Pulumi's azure-native package, specifically the ManagedCluster class from the containerservice module, to create an AKS cluster. This will be the Kubernetes cluster where your application will run.
Install Helm on your local machine: This step assumes you've already installed Helm on your machine where Pulumi is being run, as Helm is required to deploy applications into a Kubernetes cluster. You can find instructions for installing Helm in the official documentation.
Add the Helm chart repository for OFBiz: You can do this through the Helm CLI using the helm repo add command.
Install the OFBiz Helm chart: Once AKS and Helm are set up, you can use helm install to deploy the OFBiz Helm chart to your AKS cluster.
Verify the deployment: After the chart is installed, you can verify it by using the kubectl get commands to check on the deployed resources.

Let's take a look at the Pulumi code that accomplishes the AKS cluster setup:

import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";

// Create an AKS cluster.
const resourceGroupName = new azure_native.resources.ResourceGroup("myResourceGroup");

const managedCluster = new azure_native.containerservice.ManagedCluster("myAKSCluster", {
  resourceGroupName: resourceGroupName.name,
  agentPoolProfiles: [{
    count: 3,
    maxPods: 110,
    mode: "System",
    name: "agentpool",
    osDiskSizeGB: 30,
    osType: "Linux",
    vmSize: "Standard_DS2_v2",
  }],
  dnsPrefix: "myaksdns",
  kubernetesVersion: "1.19.7",
  linuxProfile: {
    adminUsername: "azureuser",
    ssh: {
      publicKeys: [{
        keyData: "ssh-rsa YOUR_PUBLIC_SSH_KEY azureuser@my-aks",
      }],
    },
  },
  identity: {
    type: "SystemAssigned",
  },
  location: resourceGroupName.location,
  // Define any other required properties here...
});

// Export the Kubeconfig
export const kubeconfig = pulumi.
    all([resourceGroupName.name, managedCluster.name])
    .apply(([resourceGroupName, clusterName]) => {
        return azure_native.containerservice.listManagedClusterUserCredentials({
            resourceGroupName: resourceGroupName,
            resourceName: clusterName,
        });
    })
    .apply(credentials => {
        const encoded = credentials.kubeconfigs[0].value;
        return Buffer.from(encoded, 'base64').toString();
    });

// Note that before run 'helm install', you'll need to configure your local Helm client by using the output kubeconfig and you have Helm installed

In this program:

We define a new AKS cluster with a single agent pool with three nodes.
We specify the desired Kubernetes version, Linux profile, and other configurations for the cluster.
We export the kubeconfig which can be used to connect to the AKS cluster with tools such as kubectl and Helm.

After running this Pulumi program, you will have a running AKS cluster ready for application deployments.

To continue with the OFBiz Helm chart deployment using Helm, you would typically perform the following steps from your command line (not within the Pulumi program):

# Make sure Helm is installed and then set up the connection to the AKS cluster:
export KUBECONFIG=./kubeconfig.yaml

# Add the Helm chart repository containing OFBiz if not already done:
helm repo add ofbiz <repository-url>

# Update your local Helm chart repository cache:
helm repo update

# Install the OFBiz Helm chart release into your AKS cluster:
helm install my-ofbiz-release ofbiz/ofbiz

# After installation, you can check the status of your release:
helm status my-ofbiz-release

# To view the application, get the external IP of the service:
kubectl get svc --namespace default

Please ensure that you replace <repository-url> with the actual URL of the Apache OFBiz Helm chart repository, and change my-ofbiz-release to your desired release name. Also, the above commands assume that your kubeconfig file is named kubeconfig.yaml and is located in your current working directory.
