1. Deploy the ckan helm chart on Azure Kubernetes Service (AKS)


    To deploy the CKAN Helm chart on Azure Kubernetes Service (AKS), you'll first need to set up an AKS cluster.


    You'll use resources provided by Pulumi's Azure Native provider to create the necessary infrastructure. The steps are as follows:

    1. Create a Resource Group: This is a logical container in which Azure resources are deployed and managed.

    2. Deploy an AKS Cluster: You'll set up the AKS cluster, which provides the managed Kubernetes service.

    3. Install Helm and the CKAN Chart: Once the cluster is up and running, you'll need to configure kubectl to communicate with the cluster and use Helm to install the CKAN Helm chart.

    Required steps before running the program

    Before running the Pulumi program, make sure you have the following prerequisites in place:

    • Pulumi CLI installed.
    • An Azure account with appropriate permissions to create resources.
    • Azure CLI installed and logged in.
    • Helm CLI installed.

    Pulumi program for setting up the AKS cluster

    Below is a TypeScript program using Pulumi. You'll find comments explaining what each part of the code does. Keep in mind that you'll need to adjust the Helm chart values to match the specific requirements for your CKAN instance.

    import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Initialize a new resource group. const resourceGroup = new azure.core.ResourceGroup("resourceGroup", { location: "WestUS", // Choose the appropriate region. }); // Step 2: Create an Azure AD service principal for the AKS cluster. const adApp = new azuread.Application("aks"); const adSp = new azuread.ServicePrincipal("aksSp", { applicationId: adApp.applicationId }); const adSpPassword = new azuread.ServicePrincipalPassword("aksSpPassword", { servicePrincipalId: adSp.id, value: "verysecurepassword", // Choose a secure password. endDate: "2099-01-01T00:00:00Z", // Set a valid end date for the password. }); // Step 3: Create the AKS cluster. const k8sCluster = new azure.containerservice.KubernetesCluster("k8sCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ name: "aksagentpool", count: 1, vmSize: "Standard_DS2_v2", // Choose the appropriate VM size. }], dnsPrefix: `${pulumi.getStack()}-kube`, linuxProfile: { adminUsername: "aksuser", sshKeys: [{ keyData: "ssh-rsa ...", // Replace with an actual SSH public key. }], }, servicePrincipal: { clientId: adApp.applicationId, clientSecret: adSpPassword.value, }, }); // Step 4: Deploy the CKAN Helm chart to the AKS cluster. // Before this step, ensure you have configured kubectl to connect to the new AKS cluster. const ckanChart = new k8s.helm.v3.Chart("ckan", { chart: "ckan", // You may need to adjust the version and repo as per your Helm chart source. version: "2.8.2", fetchOpts: { repo: "https://<helm_chart_repository_url>", // Replace with the CKAN Helm chart repository URL. }, values: { // Provide custom CKAN configuration values here. // Refer to the CKAN Helm chart documentation for necessary values. }, }, { provider: new k8s.Provider("k8sProvider", { kubeconfig: k8sCluster.kubeConfigRaw }), }); // Export the cluster name, resource group name, and kubeconfig as stack outputs. export const clusterName = k8sCluster.name; export const clusterResourceGroupName = resourceGroup.name; export const kubeconfig = k8sCluster.kubeConfigRaw;

    After putting this code in a file (for example index.ts), run it using pulumi up. This command will create the necessary Azure resources and deploy CKAN to your AKS cluster using the Helm chart. Remember to monitor the output of the pulumi command, as it shows the progress and results of the infrastructure deployment.

    Once the deployment succeeds, you'll find outputs in your console that include the cluster name, resource group name, and kubeconfig data for your AKS cluster. Use this kubeconfig to connect to your Kubernetes cluster with kubectl and manage your CKAN application.
