1. Deploy the sample-topology helm chart on Opensshift


    To deploy a Helm chart on an OpenShift cluster using Pulumi, you'll utilize the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. Helm charts are packages for Kubernetes resources, and Chart is a resource provided by Pulumi to install these packages into a Kubernetes cluster.

    Before running the Pulumi program, you need to have:

    • Pulumi CLI installed.
    • Access to an OpenShift cluster with kubectl configured to connect to it.
    • The Helm CLI installed if you're using Helm charts from your local filesystem or need to inspect the charts.

    Here's a Pulumi program in TypeScript that demonstrates how to deploy a Helm chart named sample-topology onto an OpenShift cluster:

    import * as k8s from '@pulumi/kubernetes'; // Define the settings for our Helm chart deployment. const helmChartName = 'sample-topology'; const helmChartVersion = '1.0.0'; // Specify the version of the chart. const helmChartRepo = 'https://example.com/charts'; // URL to your Helm chart repository. const releaseName = 'sample-topology-deployment'; const namespace = 'default'; // Change this to the namespace you want to deploy into. // Create a Helm chart resource using the sample-topology chart from the specified repository. const chart = new k8s.helm.v3.Chart(releaseName, { chart: helmChartName, version: helmChartVersion, fetchOpts: { repo: helmChartRepo, }, namespace: namespace, // Values in this object will configure the Helm chart. // These should reflect any custom configuration you need for the sample-topology chart. values: { // Replace these with actual configuration values for the sample-topology chart service: { type: 'ClusterIP', }, // More configuration values can be set here as needed. }, }, { provider: k8sProvider }); // Optionally, you can export the Helm release status. export const helmReleaseStatus = chart.status;
    • First, the required @pulumi/kubernetes package is imported.
    • Then, various deployment settings are configured such as the chart name, version, and repository URL.
    • The k8s.helm.v3.Chart class is used to instantiate a new Helm chart resource. You specify the name of the chart, the version, the repository where it's located, and other chart-specific configuration under the values field.
    • Finally, the Helm release status is exported to check the deployment status.

    You need to replace the helmChartRepo with the actual URL of your Helm chart repository and fill up the values object with the appropriate configurations for your chart.

    Please note that this program assumes you have already set up and authenticated with your OpenShift cluster using kubectl. The Pulumi program will use your current Kubernetes context to interact with the cluster. It is also assumed here that your Helm chart is publicly accessible via a repository URL and that you're deploying to the default namespace. Adjust these as needed for your actual setup.
