1. Deploy the min-flask helm chart on Azure Managed Openshift Service


    To deploy the min-flask Helm chart on the Azure Managed OpenShift Service using Pulumi, you'll need to set up an Azure Red Hat OpenShift cluster using the azure-native.redhatopenshift.OpenShiftCluster resource, and then deploy the Helm chart using the kubernetes.helm.v3.Chart resource from the Kubernetes provider.

    Here is a step-by-step guide, with an accompanying Pulumi TypeScript program, to accomplish that:

    1. Setting up the OpenShift Managed Cluster: To set up the Cluster, you will use the azure-native.redhatopenshift.OpenShiftCluster resource. Before creating this resource, you need to establish necessary parameters like the resourceGroupName, the location for your cluster, and the specifications for the master and worker profiles, including vmSize and subnetId for the VNet.

    2. Deploying the Helm chart: Once the cluster is provisioned, the next step is deploying the min-flask Helm chart. For this, you should have configured your kubeconfig to interact with the cluster. With Pulumi, you can use the kubernetes.helm.v3.Chart resource from the Kubernetes provider, which is designed to work with Helm charts. You will need to specify the chart name, any custom values you want to apply, and the namespace where the chart will be deployed.

    Here's how you can write the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as openshift from "@pulumi/azure-native/redhatopenshift"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision an Azure Red Hat OpenShift Cluster const cluster = new openshift.OpenShiftCluster("myCluster", { // Replace these with the appropriate values for your setup resourceGroupName: "<resource-group-name>", location: "East US", // Choose the location that is closest to you or your users clusterProfile: { domain: "<domain-name>", // Your custom domain name version: "4.4", // Specify the Openshift version resourceGroupId: `<resource-group-id>`, // ID of the resource group where the cluster and its resources will be created }, masterProfile: { vmSize: "Standard_D4s_v3", }, networkProfile: { podCidr: "", serviceCidr: "", }, workerProfiles: [{ name: "worker", vmSize: "Standard_D4s_v3", count: 3, // Number of worker nodes }], }); // Step 2: Deploy the Helm Chart // This presumes that you have already configured `kubeconfig` to point to your new OpenShift Cluster const helmChart = new k8s.helm.v3.Chart("min-flask-chart", { chart: "min-flask", // Name of the Helm chart, make sure this is the correct name // if required, specify the repository by adding a `repo` property // specify any custom values needed for your Helm chart values: {}, namespace: "default", // deploy in the default namespace, change if needed }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig }) }); // Output the public IP or hostname to access the `min-flask` application export const endpoint = pulumi.interpolate`http://${cluster.masterProfile.apiProperties.privateApiServer}`;

    Make sure to replace placeholders (<resource-group-name>, <domain-name>, <resource-group-id>, etc.) with actual values relevant to your Azure account and OpenShift configuration.

    Important Notes:

    • This program assumes that the min-flask Helm chart is available in the standard Helm chart repositories or has been added to a Helm repository you have access to. If it's a custom chart or requires specific configurations, you may need additional steps to ensure its availability.
    • When creating an OpenShift cluster, it usually involves more detailed networking, sizing, and security configurations that are beyond this basic setup.
    • The Azure Managed OpenShift Service needs to be set up with the appropriate permissions and service principals. You may need additional Azure roles and permissions added to your account for creating and managing OpenShift clusters.

    Once you write the Pulumi program, you'll run it using the Pulumi CLI. This will prompt Pulumi to perform the deployment, creating the resources in Azure and deploying your Helm chart to the OpenShift cluster.
