1. Deploy the openshift-scc helm chart on Opensshift

    TypeScript

    To deploy the openshift-scc Helm chart on an OpenShift cluster using Pulumi and the Kubernetes provider, you’ll first need to have access to an OpenShift cluster and have kubectl configured to communicate with it.

    The core resource used to manage Helm charts in Pulumi's Kubernetes provider is Chart. The Chart resource is a component that allows you to express Helm Charts as part of your Pulumi program. You can deploy an entire Helm chart as a single Pulumi component (Chart).

    Here's how you can use the Chart resource to deploy the openshift-scc Helm Chart:

    1. First, you'll need to install the Pulumi CLI and set up the Kubernetes provider.
    2. Make sure you have access to the OpenShift cluster (via kubectl).
    3. Write the Pulumi code to deploy the chart.
    4. Preview and deploy your infrastructure using Pulumi commands: pulumi up.

    Below is a TypeScript program that demonstrates these steps. It assumes that you have already set up Pulumi and authenticated with your OpenShift cluster:

    import * as k8s from "@pulumi/kubernetes"; // You need to replace 'repo_url' with the URL of the Helm repository that contains the 'openshift-scc' chart. const repoUrl = "your_helm_chart_repo_url"; // Create a new instance of the Helm Chart component for the 'openshift-scc' chart. // The 'namespace' should be the namespace where you want the chart to be deployed which could be 'default' // or any custom namespace you have created in your OpenShift cluster. const openshiftSccChart = new k8s.helm.v3.Chart("openshift-scc", { chart: "openshift-scc", version: "chart_version", // Replace with the version of the chart you want to deploy fetchOpts: { repo: repoUrl, }, namespace: "target-namespace", // Replace with the target namespace in your cluster // Include any custom values you wish to override. For example: // values: { // someKey: "someValue", // } }, { provider: new k8s.Provider("k8s-provider", { // This is where you provide the kubeconfig details kubeconfig: `your_kubeconfig_contents`, }), }); // Export the name of the chart namespace which might be handy for operations post deployment export const chartNamespace = openshiftSccChart.namespace;

    Replace your_helm_chart_repo_url with the actual URL of the repo where the openshift-scc chart is located. Additionally, replace chart_version with the version of the chart you want to deploy, target-namespace with the namespace where you want the chart to be deployed, and your_kubeconfig_contents with the contents of your kubeconfig file that contains the connection details to your OpenShift cluster.

    This program does the following:

    • It imports the Kubernetes package from Pulumi.
    • It defines the Helm chart to be deployed, specifying the repo URL, chart name, version, and target namespace.
    • It configures the Kubernetes provider with kubeconfig.
    • It deploys the Helm chart to your OpenShift cluster.
    • It exports the namespace where the chart is deployed.

    After writing this code in a file, say index.ts, you run the following Pulumi commands to deploy it:

    pulumi stack init dev pulumi up

    The pulumi stack init command is used to create a new stack, named dev in this case, which will keep track of the state of your infrastructure. The pulumi up command is used to preview and deploy the changes.

    When you run pulumi up, Pulumi will perform a preview showing you what resources will be created, modified, or destroyed. Once you confirm the operation, Pulumi will proceed with the deployment.

    Remember to look at the official documentation for specific configuration parameters relevant to openshift-scc that you might need to pass to the Helm chart through the values property: Helm Chart Resource | Pulumi.
