Deploy the pact-broker helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the Pact Broker Helm chart on Azure Kubernetes Service (AKS), you'll need to perform several steps using Pulumi:

Provision an AKS cluster: You need an AKS cluster where you can deploy your applications. Pulumi can define and create this cluster for you.
Install the Helm chart: You will need to install the Pact Broker Helm chart onto your AKS cluster. Pulumi's Chart resource from the kubernetes provider will enable you to deploy Helm charts.

Here's a detailed guide on how you can achieve this with Pulumi, followed by the corresponding TypeScript program:

Step 1: Set up the AKS Cluster

We'll start by provisioning an AKS cluster using the azure-native package. The ProvisionedCluster resource will create a Kubernetes cluster in Azure. You will require some specifics, like the location and resource group that you want the cluster to be in, and any other Azure-specific configurations.

Step 2: Deploy the Pact Broker Helm Chart

With the AKS cluster in place, you'll deploy the Helm chart for the Pact Broker. To do this, you'll utilize Pulumi's integration with Helm via the Chart resource provided by the kubernetes package.

The Pulumi Program

Below is the complete Pulumi TypeScript program that performs the steps mentioned above. This program assumes that you have the Pulumi CLI installed and have already logged in to your Azure account using the Azure CLI.

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

// Create an Azure Resource Group
const resourceGroup = new azure_native.resources.ResourceGroup("pactBrokerResourceGroup");

// Create an AKS cluster.
const aksCluster = new azure_native.containerservice.ManagedCluster("pactBrokerCluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 2,
        maxPods: 110,
        mode: "System",
        name: "agentpool",
        osDiskSizeGB: 30,
        osType: "Linux",
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: "pactbrokerdns",
    enableRBAC: true,
    kubernetesVersion: "1.21.2",
    linuxProfile: {
        adminUsername: "pulumiadmin",
        ssh: {
            publicKeys: [{
                keyData: "<YOUR_SSH_PUBLIC_KEY>",
            }],
        },
    },
    location: resourceGroup.location,
    nodeResourceGroup: "pactBrokerNodeResourceGroup",
});

// Export the kubeconfig for the AKS cluster
export const kubeconfig = pulumi.all([aksCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) =>
    azure_native.containerservice.listManagedClusterUserCredentials({
        resourceName: clusterName,
        resourceGroupName: rgName,
    })).apply(creds => Buffer.from(creds.kubeconfigs[0].value, "base64").toString());

// Create a Kubernetes provider instance that uses our AKS cluster kubeconfig
const k8sProvider = new kubernetes.Provider("pactBrokerK8sProvider", {
    kubeconfig: kubeconfig,
});

// Deploy the Pact Broker Helm chart using Pulumi's Kubernetes provider
const pactBrokerChart = new kubernetes.helm.v3.Chart("pactBrokerHelmChart", {
    chart: "pact-broker",
    fetchOpts: {
        repo: "https://helm.pact.io",
    },
    // You may need to provide appropriate values or configuration depending on the chart
    // values: {},
}, { provider: k8sProvider });

// Export the AKS cluster name and status
export const clusterName = aksCluster.name;
export const clusterStatus = aksCluster.provisioningState;

In the above program, don't forget to replace <YOUR_SSH_PUBLIC_KEY> with your actual SSH public key. This is necessary to access the nodes in the AKS cluster securely.

The kubeconfig entry is exported so that you can interact with your AKS cluster using kubectl or other Kubernetes tooling. You should keep this information secure.

Remember, you'll need to install the Pulumi CLI and log in to your Azure account to run this program successfully.

Running the Program

To run this program:

Save this TypeScript code to a file named index.ts.
Run npm install to install the required dependencies.
Run pulumi up to execute the Pulumi program.

This will provision the AKS cluster and deploy the Pact Broker Helm chart onto it.
