1. Deploy the yadms helm chart on Azure Managed Openshift Service

    TypeScript

    To deploy a Helm chart on Azure Managed OpenShift, you need to set up an OpenShift cluster and then deploy the Helm chart to it. Below, I will guide you through the process step by step using Pulumi with TypeScript.

    First, we'll create the OpenShift Managed Cluster using the azure-native.containerservice.OpenShiftManagedCluster resource. You'll need to have a resource group and a DNS prefix ready for this.

    Once the cluster is ready, you can then deploy the Helm chart to it using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider.

    Here's a program that illustrates how to do this:

    import * as pulumi from "@pulumi/pulumi";
import * as azureNative from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";

// Define the config for the Azure Managed OpenShift cluster deployment.
const config = new pulumi.Config();
const location = config.require("location");
const resourceGroupName = config.require("resourceGroupName");
const openshiftDnsPrefix = config.require("openshiftDnsPrefix");

// Create a new Azure resource group for the OpenShift cluster.
const resourceGroup = new azureNative.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: resourceGroupName,
    location: location,
});

// Deploy an Azure Managed OpenShift cluster.
const openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster("openshiftCluster", {
    resourceGroupName: resourceGroupName,
    resourceName: "yadmsCluster",
    location: location,
    openShiftVersion: "4.3", // specify the desired OpenShift version
    networkProfile: {
        vnetCidr: "10.0.0.0/8",
    },
    masterPoolProfile: {
        count: 3, // number of master nodes
        vmSize: "Standard_D4s_v3", // VM size of the master nodes
    },
    agentPoolProfiles: [{
        // You can define multiple agent pools if necessary
        name: "agentpool",
        role: "compute", // could also be 'infra' for infrastructure nodes
        count: 3, // number of agent nodes
        vmSize: "Standard_D4s_v3", // VM size of the agent nodes
    }],
    // The DNS prefix must be unique across all existing cluster in an Azure subscription.
    dnsPrefix: openshiftDnsPrefix,
});

// We need the Kubeconfig to deploy the Helm chart to the OpenShift cluster.
const kubeconfig = openshiftCluster.config;

// Create a new K8s provider using the kubeconfig from the OpenShift cluster.
const k8sProvider = new k8s.Provider("openshiftK8sProvider", {
    kubeconfig: kubeconfig,
});

// Finally, deploy the yadms Helm chart to the OpenShift cluster using the Pulumi Kubernetes provider.
const chart = new k8s.helm.v3.Chart("yadmsChart", {
    chart: "yadms",
    version: "1.0.0", // specify the chart version if necessary
    // Define the repository if it's not a stable chart.
    fetchOpts: {
        repo: "http://chart-repository-url.com/",
    },
    // Values to pass to the Helm chart.
    values: {
        // Define your values here for Helm chart configuration
    },
}, { provider: k8sProvider });

// Export the public IP address of the cluster's ingress controller to access yadms.
export const yadmsEndpoint = pulumi.output(chart).apply(chart =>
    chart.getResourceProperty("v1/Service", "yadms", "status")
).apply(status => status.loadBalancer.ingress[0].ip);

    This program performs the following actions:

    • It creates a new Azure Resource Group for your OpenShift cluster.
    • It creates an Azure Managed OpenShift cluster with the specified number of master and compute nodes.
    • It retrieves the kubeconfig of the newly created OpenShift cluster.
    • It provides the Pulumi Kubernetes provider with the kubeconfig so that you can deploy resources to the OpenShift cluster.
    • It deploys the yadms Helm chart from the specified repository to the OpenShift cluster.

    Remember to replace "http://chart-repository-url.com/" with the actual URL of the Helm chart repository where yadms is hosted.

    To run the Pulumi program:

    1. Make sure you have the Pulumi CLI installed along with Node.js and npm.
    2. Create a new directory for the Pulumi project and run pulumi new typescript to create a new Pulumi TypeScript project.
    3. Replace the contents of index.ts with the code above.
    4. Run npm install to install the required dependencies.
    5. Configure the required variables using pulumi config set, e.g., pulumi config set location westus2.
    6. Run pulumi up to preview and deploy the resources.

    Please note that provisioning an Azure Managed OpenShift cluster might take some time. Once it's ready and the yadms Helm chart is deployed, you can use the exported IP address to access YADMS in a browser.
