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


    To accomplish your goal of deploying the OpenWhisk Helm chart on an Azure Kubernetes Service (AKS) cluster, you'll need to:

    1. Create an AKS cluster on Azure.
    2. Configure the Kubernetes provider to connect to your AKS cluster.
    3. Use the Helm Chart resource from the Kubernetes provider to deploy OpenWhisk on your cluster.

    Let me walk you through step by step.

    Step 1: Create an AKS Cluster

    You are going to use the azure-native package, specifically the ManagedCluster resource, which is responsible for creating an AKS cluster.

    Step 2: Configure Kubernetes Provider

    Once the AKS cluster is ready, you'll grab its kubeconfig and use it to configure the Kubernetes provider. This allows Pulumi to connect to your AKS cluster and manage Kubernetes resources.

    Step 3: Deploy OpenWhisk Using Helm Chart

    This is where you'll use the Kubernetes provider to deploy OpenWhisk using its Helm chart. The Chart resource from the kubernetes package helps you deploy Helm charts to your cluster.

    Below is the TypeScript program to deploy OpenWhisk to AKS with Pulumi:

    import * as pulumi from '@pulumi/pulumi'; import * as azure_native from '@pulumi/azure-native'; import * as kubernetes from '@pulumi/kubernetes'; // Create an AKS cluster. const aksCluster = new azure_native.containerservice.ManagedCluster('aksCluster', { resourceGroupName: 'myResourceGroup', // Replace with the name of your resource group kubernetesVersion: '1.21.9', // Specify your desired Kubernetes version agentPoolProfiles: [{ count: 2, // Specify the number of nodes in the node pool vmSize: 'Standard_DS2_v2', // Specify the size of each node mode: 'System', name: 'agentpool', }], // Specify additional settings such as identity, network configuration, etc. (if required) }); // Export the kubeconfig for the AKS cluster. export const kubeconfig = aksCluster.kubeconfig.apply(c => c); // Create a Kubernetes provider instance using the kubeconfig from the AKS cluster. const k8sProvider = new kubernetes.Provider('k8sProvider', { kubeconfig: kubeconfig, }); // Deploy the OpenWhisk Helm chart using the Kubernetes provider. const openWhiskChart = new kubernetes.helm.v3.Chart('openwhisk', { chart: 'openwhisk', // Replace with the correct chart name if it's different version: '1.0', // Specify the version of the chart fetchOpts: { repo: 'https://openwhisk.apache.org/charts', // Official OpenWhisk Helm repository }, }, { provider: k8sProvider }); // Export the IP address or hostname by which OpenWhisk can be accessed. export const openWhiskUrl = openWhiskChart.getResourceProperty('v1/Service', 'openwhisk-nginx', 'status') .apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    Explanation of the Resources:

    • ManagedCluster: Creates a new AKS cluster within the specified resource group, with a specified version of Kubernetes and a configurable number of nodes.

    • Provider: The Kubernetes provider allows Pulumi to perform actions on the Kubernetes cluster created by ManagedCluster. Here it is configured with the kubeconfig output from the AKS cluster.

    • Chart: This deploys a Helm chart to the cluster. Helm is a package manager for Kubernetes, and we're specifying the OpenWhisk chart from its official repository.

    Make sure to replace the placeholder values such as 'myResourceGroup' with the actual names of your Azure resources.

    After writing this code to a index.ts file in a Pulumi project, you can deploy the resources by running pulumi up from the command line. Pulumi will prompt you with a summary of the resources to be created and ask for confirmation before proceeding with the deployment.

    The export statements at the end of the code snippet provide you with outputs that you can use to interact with your AKS cluster and OpenWhisk deployment. kubeconfig would be used to configure kubectl if you want to interact with your cluster via the command line. openWhiskUrl provides the URL to access the OpenWhisk API once it's deployed.

    Remember to have the Azure CLI logged in and Pulumi configured with an account to run the commands properly.
