1. Deploy the voltha-adapter-openolt helm chart on Azure Kubernetes Service (AKS)


    To deploy the voltha-adapter-openolt Helm chart on Azure Kubernetes Service (AKS), we need to follow these steps:

    1. Create an AKS Cluster: We will use the azure-native provider from Pulumi to provision an AKS cluster. This involves creating a resource group (if it does not exist already) and then defining the AKS cluster within it.

    2. Setup Kubernetes Configuration: Once the AKS cluster is provisioned, we need to configure kubectl to connect to the new cluster. This is typically handled by Pulumi automatically when it creates the cluster.

    3. Install the Helm Chart: We will make use of the Pulumi Kubernetes provider to deploy the Helm chart onto the AKS cluster. Helm is a package manager for Kubernetes that allows users to easily deploy applications in the form of charts. We can install the chart with default settings or provide a custom values.yaml configuration.

    4. Verify the Deployment: Lastly, we verify that the Helm chart was deployed correctly, which might include checking for running Pods, Services, or any other Kubernetes resources created by the Helm chart.

    Below I provide the TypeScript program that encompasses these steps. Please note that while the AKS and Kubernetes providers are being used, the voltha-adapter-openolt Helm chart must be available in a public or private Helm repository, and access is configured accordingly.

    import * as pulumi from '@pulumi/pulumi'; import * as azure_native from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Create a resource group if one doesn't exist const resourceGroup = new azure_native.resources.ResourceGroup('myResourceGroup', { resourceGroupName: 'myResourceGroup', location: 'WestUS', // Change to your desired location }); // Create the AKS cluster const cluster = new azure_native.containerservice.ManagedCluster('myAksCluster', { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: 'Standard_DS2_v2', mode: 'System', name: 'agentpool', }], dnsPrefix: 'myK8sCluster', kubernetesVersion: '1.20.7', }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfig.apply(c => Buffer.from(c.kubeconfigs[0].value, 'base64').toString()); // Create a Kubernetes provider instance using the kubeconfig const k8sProvider = new k8s.Provider('k8sProvider', { kubeconfig: kubeconfig, }); // Deploy the Helm chart const volthaChart = new k8s.helm.v3.Chart('voltha', { repo: 'myhelmrepo', // Replace with the Helm repository name that contains the chart chart: 'voltha-adapter-openolt', // Replace with the actual chart name in case it differs // Specify any custom values.yaml configuration values: { service: { type: 'LoadBalancer', // or 'ClusterIP' depending on your requirements }, }, }, { provider: k8sProvider }); // Export the endpoint of the LoadBalancer (if any) created by the Helm chart export const volthaServiceEndpoint = volthaChart.getResource('v1/Service', 'voltha-adapter-openolt').status.apply(status => { return status.loadBalancer.ingress[0].ip; });

    In this program, we:

    • Import the necessary Pulumi packages.
    • Create a resource group specific to our deployment.
    • Define an AKS cluster within the resource group and export the kubeconfig needed to communicate with the cluster from outside.
    • Declare a Provider resource so that Pulumi uses the correct context when applying changes to our AKS cluster.
    • Deploy the voltha-adapter-openolt Helm chart using the Chart resource, along with any custom configuration specified in the values object.
    • (Optional) Export the endpoint, making it easier to interact with the deployed service.

    You will need to adjust parameters such as the resource group name, cluster name, Kubernetes version, Helm repository, and chart values to match your specific requirements. After the chart is deployed, you can manage it through Pulumi or standard Kubernetes tooling like kubectl.
