1. Deploy the ibmcloud helm chart on Opensshift


    To deploy an IBM Cloud Helm chart on OpenShift using Pulumi, we'll use the kubernetes package to provision resources on a Kubernetes cluster. This is assuming that you already have access to an OpenShift cluster and have configured appropriate credentials for Pulumi to interact with your Kubernetes cluster.

    First, you’ll need to install the @pulumi/kubernetes npm package, which provides the necessary Pulumi resource types for Kubernetes.

    npm install @pulumi/kubernetes

    Next, let’s create a Pulumi program in TypeScript. The program will perform the following steps:

    1. Import the Pulumi Kubernetes SDK.
    2. Define a new Helm chart from a repository or local path.

    Here is the Pulumi program for deploying a Helm chart to your OpenShift cluster:

    import * as k8s from "@pulumi/kubernetes"; // Initialize a Kubernetes provider using the context of the OpenShift cluster // that you have configured locally or using any other applicable configuration. const provider = new k8s.Provider("openshift", { // You might need to specify additional options here if the default context // from your kubeconfig is not the OpenShift cluster you want to work with. }); // Define the IBM Cloud Helm chart // For the `chart` value, provide the name of the chart you want to deploy. // For `repo`, provide the URL of the Helm repository that contains the chart. const ibmCloudChart = new k8s.helm.v3.Chart("ibmcloud-chart", { repo: "ibm-cloud-helm-repo-url", // Replace with the actual Helm chart repository URL chart: "chart-name", // Replace with the chart name version: "chart-version", // Optionally, specify a version // If your chart requires custom values, specify them as an object. // For example, use `values: { key: "value" }`. values: {}, // Replace with your chart values namespace: "target-namespace", // Optionally, specify the namespace to deploy the chart in }, { provider }); // If you need, you can add additional logic to react to the deployment, // such as exporting endpoint URLs or checking resource statuses. // Export any important information from the deployment export const chartName = ibmCloudChart.metadata.name;

    In this program:

    • We create a new instance of the Provider class, which encapsulates the configuration for your Kubernetes/OpenShift cluster. This configuration includes details such as the API endpoint and authentication credentials.
    • We then define a new Helm chart resource, which represents the Helm chart you want to deploy. The repo field should point to the Helm repository where your chart is hosted, and the chart field should be the name of the chart itself. Optionally, you can specify a version.
    • In the values object, you'd include any custom values your Helm chart accepts, which override the default values. Make sure to modify the values object based on your Helm chart's requirements.
    • Optionally, you can specify a namespace where the Helm chart should be deployed. If you don't specify one, it will be deployed to the default namespace.
    • We're exporting chartName which can be helpful if your Pulumi program will be interacting with other resources and needs to reference the Helm chart's name.

    You’ll need the Pulumi CLI installed and set up to interact with your OpenShift cluster. You’ll run pulumi up to deploy this Helm chart to your OpenShift cluster. Make sure your kubeconfig is set up to access your OpenShift cluster from the command line. If you need a different configuration, you can modify the Provider resource accordingly.

    Remember that this program does not initialize a Pulumi project or configure the stack. You should run this code within the context of a Pulumi project. If you need help setting up a Pulumi project or understanding other related concepts, please consult Pulumi’s Getting Started guide for Kubernetes.
