1. Deploy the Knative helm chart on Opensshift


    To deploy the Knative Helm chart on OpenShift, you will utilize Pulumi's Kubernetes provider to interact with the OpenShift cluster and the Helm Chart resource to deploy Knative. Below is a Pulumi program in TypeScript that demonstrates how to do this.

    This program assumes that you have already configured your Pulumi environment to connect to your OpenShift cluster and that the Helm chart for Knative is available in a Helm repository that you have access to.

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

    1. Imports: Include necessary modules from Pulumi and other libraries for Kubernetes management.
    2. Helm Chart Deployment: Use the Chart resource from the @pulumi/kubernetes/helm/v3 module to deploy Knative. This resource abstracts Helm chart deployment logic into a Pulumi resource.
    3. Helm Chart Configuration: Configure the chart with the necessary values, such as the chart name, version (if specific one needed), and any custom values you want to override. We're deploying Knative and therefore need to specify the right Helm repository.

    Below is the full TypeScript program:

    import * as k8s from '@pulumi/kubernetes'; const knativeReleaseName = 'knative'; const knativeNamespace = 'knative-serving'; const knativeHelmRepoName = 'knative'; // This should correspond to actual Helm repo name const knativeHelmRepoUrl = 'https://knative-charts.storage.googleapis.com'; // Replace with the actual Helm repo URL const knativeChartVersion = '<chart-version>'; // Replace with the specific version you want to deploy // Create a namespace for Knative if it doesn't already exist const knativeNs = new k8s.core.v1.Namespace(knativeReleaseName, { metadata: { name: knativeNamespace, }, }, { provider: <openshift-provider> }); // Replace <openshift-provider> with an instance of k8s.Provider configured for OpenShift // Deploy the Knative Helm chart into the created namespace const knative = new k8s.helm.v3.Chart(knativeReleaseName, { chart: 'knative', version: knativeChartVersion, namespace: knativeNs.metadata.name, fetchOpts: { repo: knativeHelmRepoUrl, }, }, { provider: <openshift-provider> }); // Replace <openshift-provider> with the provider from above // Export the Knative ingress endpoint export const knativeIngress = knative.getResource('v1/Service', `${knativeNamespace}/knative-ingress`);

    Before running this Pulumi program, you will need to replace:

    • <chart-version> with the version number of the Knative chart you want to deploy.
    • <openshift-provider> with an instance of the Kubernetes provider that's configured to interact with your OpenShift cluster. This involves setting up the kubeconfig file or any authentication mechanism your OpenShift cluster uses.

    Run the Pulumi command pulumi up in the same directory as this code to perform the deployment. Review the changes Pulumi proposes, and then confirm them to proceed with the deployment on your OpenShift cluster.

    Remember to configure the Pulumi Kubernetes provider with the appropriate context for your OpenShift cluster. Additionally, ensure that Helm and Knative are supported and properly configured within your OpenShift environment.
