1. Deploy the ts-server helm chart on Opensshift


    To deploy the ts-server Helm chart on an OpenShift cluster using Pulumi, you'll start by setting up a Pulumi program that defines the required Kubernetes resources. The @pulumi/kubernetes package provides the necessary tools to deploy Helm charts in a Kubernetes or OpenShift cluster.

    Before you code, you'll need:

    • Pulumi CLI installed and configured.
    • Access to an OpenShift cluster and the kubectl command-line tool configured to communicate with your cluster.
    • Details of the Helm chart you want to deploy (ts-server) including the Helm repository URL if it's not a locally available chart.

    Here's a step-by-step explanation of the program:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a Helm chart resource, specifying the OpenShift namespace you want to deploy to, and any other pertinent configurations such as values overrides.

    Now, let's write the code to deploy the ts-server Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Define the settings for the Helm chart. const tsServerChart = new kubernetes.helm.v3.Chart("ts-server-chart", { // Assuming 'ts-server' is the name of the Helm chart. chart: "ts-server", // Replace this with the correct repository URL or local path. fetchOpts: { repo: "http://<helm-chart-repository-url>", }, // Specify the namespace where this chart will be installed. namespace: "my-namespace", // Add any value overrides if necessary, e.g. to customize the Helm chart installation. values: { // For example, setting the service type to LoadBalancer service: { type: "LoadBalancer", }, }, }, { provider: yourOpenshiftProvider }); // You will need to create a provider that targets your OpenShift cluster. // Export the URL of the deployed ts-server (assuming ts-server creates a service with an external endpoint). // Replace `serviceName` with the actual service name created by your Helm chart. const tsServerService = tsServerChart.getResourceProperty("v1/Service", "serviceName", "status"); export const tsServerUrl = pulumi.interpolate`http://${tsServerService.apply(s => s.loadBalancer.ingress[0].ip)}`;

    In this script:

    • chart: The name of the chart in the Helm repository.
    • fetchOpts.repo: The URL of the Helm repository that hosts the ts-server chart.
    • namespace: The namespace in OpenShift where you want to deploy the chart. Make sure to replace my-namespace with the actual OpenShift namespace you intend to use.
    • values: Here is where you can provide any configuration options that are specific to the ts-server chart. As an example, I've shown how you could set the service type to LoadBalancer. You'll need to consult the ts-server chart's documentation for the correct values.

    The provider argument would be an instance of a Pulumi Kubernetes provider pre-configured to target your OpenShift cluster. This requires setting up the provider with the appropriate context if it's different from the default one in your kubeconfig.

    Lastly, the program exports the URL of the ts-server service. The getResourceProperty function tries to pull out the external IP from the LoadBalancer service that the Helm chart would create. You need to replace serviceName with the actual name of the service that would be created by your Helm chart.

    Remember that to run this Pulumi program, you'll need to execute pulumi up command via the CLI. This will provision the resources as per the above script and provide you with an output of the ts-server URL if the chart provisions an external-facing LoadBalancer service. If the service is of a different type, you'll need to adjust the export statement accordingly.
