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


    To deploy the Flink Kubernetes Operator Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we will complete the following steps:

    1. Create an AKS cluster: We will use the ProvisionedCluster resource from the azure-native package to create an Azure Kubernetes Service cluster.

    2. Deploy the Helm chart: We will use the Chart resource from the kubernetes package to deploy the Flink Kubernetes Operator Helm chart onto the AKS cluster.

    Here is a step-by-step Pulumi program written in TypeScript that accomplishes these tasks:

    Detailed Explanation

    Before starting the Pulumi program:

    • Ensure that you have the azure-native and kubernetes providers installed in your Pulumi project. These are necessary for creating AKS clusters and deploying Helm charts respectively.
    • Make sure you have access to an Azure subscription and the necessary permissions to create resources.
    • You should also have configured your Pulumi Azure provider with the appropriate credentials.

    Pulumi Program

    import * as pulumi from '@pulumi/pulumi'; import * as azure from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create an Azure Kubernetes Service (AKS) cluster // We create a Resource Group to contain the AKS cluster const resourceGroup = new azure.resources.ResourceGroup('myResourceGroup'); // We define the settings for our AKS cluster const aksCluster = new azure.containerservice.ManagedCluster('myAKSCluster', { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, // Set the number of nodes you want for your AKS cluster maxPods: 110, mode: 'System', name: 'agentpool', osDiskSizeGB: 30, osType: 'Linux', vmSize: 'Standard_DS2_v2', }], dnsPrefix: `aks-${pulumi.getStack()}`, // Enable RBAC for secure interaction with the Kubernetes API enableRBAC: true, kubernetesVersion: '1.18.14', // A Linux profile is required for the Kubernetes cluster // Provide an SSH key to use with the Kubernetes cluster linuxProfile: { adminUsername: 'aksuser', ssh: { publicKeys: [{ keyData: process.env.SSH_PUBLIC_KEY, // Replace with your SSH public key }], }, }, }); // Export the AKS cluster's kubeconfig export const kubeconfig = pulumi. all([aksCluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, }); }).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Step 2: Deploy the Flink Kubernetes Operator Helm chart onto the AKS cluster const flinkOperatorChart = new k8s.helm.v3.Chart('flink-operator', { chart: 'flink-kubernetes-operator', version: '0.1.0', // Use the version of the chart you want to deploy fetchOpts: { repo: 'https://my-repository.github.io/charts/', // Replace with the repository where the chart is located }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig: kubeconfig, }), }); // If you need to specify a custom value, you can add a `values` parameter: /* const flinkOperatorChartCustomValues = new k8s.helm.v3.Chart('flink-operator', { chart: 'flink-kubernetes-operator', version: '0.1.0', fetchOpts: { repo: 'https://my-repository.github.io/charts/', }, values: { // Specify your custom values here }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig: kubeconfig, }), }); */

    In this program:

    • We first create an AKS cluster by declaring the necessary ManagedCluster with a specific configuration for node size, count, and the version of Kubernetes we want to run. Make sure to replace process.env.SSH_PUBLIC_KEY with your actual SSH public key.
    • We export the kubeconfig, which is necessary for our Kubernetes provider to interact with the AKS cluster.
    • We then deploy the Flink Kubernetes Operator using a Helm chart. You need to replace the repository URL in the fetchOpts parameter with the actual URL where the Flink Kubernetes Operator Helm chart is located.
    • The Provider resource is used to make sure that the Helm chart is deployed to the newly created AKS cluster instead of your local or default Kubernetes cluster.
    • If needed, you can provide custom values for the Helm chart by adding a values parameter to the Chart resource.

    This program will establish an AKS cluster and deploy the Flink Kubernetes Operator to it. When executing this Pulumi program, the output will contain the kubeconfig needed to interact with the AKS cluster using kubectl.
