1. Deploy the gitpod-selfhosted helm chart on Azure Managed Openshift Service

    TypeScript

    To deploy the gitpod-selfhosted Helm chart on the Azure Managed OpenShift Service using Pulumi, we will follow these steps:

    1. Create an Azure OpenShift Managed Cluster using the azure-native.containerservice.OpenShiftManagedCluster resource.
    2. Install the Gitpod self-hosted Helm chart onto the OpenShift Cluster using the kubernetes.helm.sh/v3.Chart resource.

    Below is the detailed TypeScript program using Pulumi to achieve these goals:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Define the OpenShift Managed Cluster in Azure const openShiftManagedCluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { resourceGroupName: "myResourceGroup", resourceName: "myOpenShiftCluster", location: pulumi.output(azure_native.core.getLocation({ location: "<desired Azure location>", })), openShiftVersion: "v4.3", // Specify the OpenShift version you want to deploy networkProfile: { vnetCidr: "10.0.0.0/8", }, masterPoolProfile: { count: 3, // The number of master nodes (3 is recommended for production clusters) vmSize: "Standard_D4s_v3", // Size of the virtual machines }, agentPoolProfiles: [{ name: "agentpool", count: 5, // Number of agent nodes, adjust this based on the expected workload vmSize: "Standard_D4s_v3", // Size of the virtual machines role: "compute", // Agent role - this sets the nodes to be compute nodes osType: "Linux", // OS type for the agents }], // Additional properties like authProfile, tags, etc. may be set based on requirements. }); // Retrieve the KubeConfig from the deployed OpenShift cluster const kubeconfig = pulumi.all([openShiftManagedCluster.name, openShiftManagedCluster.resourceGroupName]).apply(([name, resourceGroupName]) => { return azure_native.containerservice.listOpenShiftManagedClusterUserCredentials({ resourceName: name, resourceGroupName: resourceGroupName, }).then(creds => { const encoded = creds.kubeconfigs[0].value; const buff = new Buffer(encoded, 'base64'); return buff.toString('utf-8'); }); }); // Create a provider for the OpenShift cluster so that Helm charts can be deployed to it. const openshiftProvider = new k8s.Provider("openshiftProvider", { kubeconfig: kubeconfig, }); // Define the Helm chart resource for Gitpod, utilizing the Gitpod self-hosted Helm chart const gitpodHelmChart = new k8s.helm.v3.Chart("gitpod-selfhosted", { repo: "gitpod", // Specify the repository for the Gitpod Helm chart chart: "gitpod", // Name of the chart version: "<chart version>", // Specify the version of the Gitpod chart you want to deploy // You can provide custom values for your Gitpod installation using 'values' values: { // ... include any necessary configuration values here }, }, { provider: openshiftProvider }); // Export the cluster's kubeconfig export const kubeConfig = kubeconfig;

    Explanation:

    • The azure_native.containerservice.OpenShiftManagedCluster resource is used to provision an Azure OpenShift Managed Cluster. Here, you define properties like the resource group, name, location, OpenShift version, network profiles, Master and Agent pool profiles.
    • The kubeconfig is retrieved once the OpenShift cluster has been provisioned. This is necessary to communicate with the OpenShift cluster and deploy applications to it.
    • The k8s.Provider is the Kubernetes provider that uses the kubeconfig of the OpenShift cluster that we've just deployed. This allows Pulumi to use this specific provider to communicate with the OpenShift cluster.
    • The k8s.helm.v3.Chart resource is then used to deploy the Gitpod Helm chart to the OpenShift cluster using the provider we've set up. In the values object, you would specify the Gitpod configuration. It is important to fill in the <chart version> placeholder with the specific version of the chart you want to deploy.
    • Finally, the kubeconfig is exported, which allows you to interact with the cluster outside of Pulumi using kubectl or another Kubernetes tool.

    Make sure to replace <desired Azure location> and <chart version> with specific values according to your deployment needs.

    After running this Pulumi program, the OpenShift cluster will be deployed in your Azure account and the Gitpod self-hosted application will be running on it.
