1. Deploy the pingdom-operator helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    Deploying the pingdom-operator Helm chart on Azure Kubernetes Service (AKS) involves several steps. First, you'll need to provision an AKS cluster if you don't have one already. Then, you'll configure kubectl to interact with your AKS cluster. Finally, you will use the Helm package manager to install the pingdom-operator chart.

    Below is a Pulumi TypeScript program that demonstrates how to achieve these steps. I will walk you through this process step-by-step:

    1. Provision an AKS cluster: We will use the azure-native package to provision an AKS cluster. This involves creating a resource group and then provisioning the AKS cluster itself.

    2. Configure kubectl: Normally you would also need to configure kubectl to interact with the newly-created AKS cluster by setting the kubeconfig, but with Pulumi's kubernetes provider, this will be handled automatically for you. It uses the AKS kubeconfig by default when the cluster resource is referenced.

    3. Install the pingdom-operator Helm chart: For installing Helm charts, Pulumi provides a Helm Chart resource that we can use. We will set the necessary chart values which may include information such as the pingdom API key, secret, and other configurations needed by the operator.

    Now, let's create the Pulumi TypeScript program:

    import * as pulumi from '@pulumi/pulumi'; import * as azure_native from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new resource group const resourceGroup = new azure_native.resources.ResourceGroup('myResourceGroup'); // Step 2: Create the AKS cluster const cluster = new azure_native.containerservice.ManagedCluster('myAksCluster', { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 1, maxPods: 110, mode: 'System', name: 'agentpool', osDiskSizeGB: 30, osType: 'Linux', vmSize: 'Standard_DS2_v2', }], dnsPrefix: pulumi.getStack(), enableRBAC: true, kubernetesVersion: '1.21.2', linuxProfile: { adminUsername: 'adminuser', ssh: { publicKeys: [{ keyData: '<ssh-rsa PUBLIC KEY>', }], }, }, nodeResourceGroup: `MC_azure-${pulumi.getStack()}`, // For educational purposes, you should replace `<ssh-rsa PUBLIC KEY>` with your actual SSH public key. }); // Export the cluster name and kubeconfig export const clusterName = cluster.name; export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, resourceGroupName]) => azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: resourceGroupName, resourceName: clusterName, }) ).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Step 3: Install the 'pingdom-operator' Helm chart on the AKS cluster const pingdomOperatorChart = new k8s.helm.v3.Chart('pingdom-operator', { chart: 'pingdom-operator', fetchOpts: { repo: 'http://charts.pingdom-operator.example.com/', // Replace with actual repo URL }, // Values to pass to the Helm chart; replace these with actual details values: { apiKey: 'YOUR_PINGDOM_API_KEY', apiSecret: 'YOUR_PINGDOM_API_SECRET', // ... other necessary values }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig }) }); // Export Helm Chart status export const pingdomOperatorStatus = pingdomOperatorChart.status;

    Here's a detailed breakdown of the program:

    • First, we import required Pulumi packages.
    • We create a resource group for containing all our Azure resources (in this case, our Kubernetes cluster).
    • We provision an AKS cluster using the ManagedCluster resource from the azure-native package. Make sure you replace the placeholder with your actual SSH public key where indicated.
    • We export kubeconfig which will be used to interact with your AKS cluster programmatically. Pulumi securely manages this sensitive information.
    • Then, we install the pingdom-operator Helm chart using Pulumi's k8s.helm.v3.Chart resource. You'll need to replace placeholder values with the actual values required by the pingdom-operator chart.
    • Finally, we export the status of the Helm chart deployment as pingdomOperatorStatus.

    Please replace the placeholders with the actual values of your cluster configuration and the pingdom-operator Helm chart. You may find the actual values in the official pingdom-operator documentation or where you store the chart. You should also have the Azure CLI installed and configured with the appropriate credentials, along with Pulumi CLI set up on your local machine.

    To run this program:

    1. Save it as index.ts in a new Pulumi project directory.
    2. Run npm install @pulumi/pulumi @pulumi/azure-native @pulumi/kubernetes to install the dependencies.
    3. Run pulumi up to execute the code and stand up the infrastructure.

    Remember, Pulumi stores the state of your infrastructure, enabling you to safely modify and manage your cloud resources.
