1. Deploy the angular-chart helm chart on Opensshift


    To deploy an Angular application using the Helm chart on an OpenShift cluster with Pulumi, you'll need to set up your OpenShift environment, write the Pulumi program to specify the deployment, and execute the program to create the resources.

    Here is a TypeScript program that demonstrates how you can use Pulumi to deploy a Helm chart onto an OpenShift cluster. We will make use of the kubernetes.helm.v3.Chart resource defined by Pulumi's Kubernetes provider. This resource represents a Helm Chart, a package of pre-configured Kubernetes resources.

    Ensure that you have configured Pulumi with the appropriate Kubernetes context for your OpenShift cluster, so that Pulumi can communicate with your cluster.

    Here's the program that you can use:

    import * as k8s from "@pulumi/kubernetes"; // Replace these variables with the appropriate values for your setup. const chartName = "angular-chart"; const chartVersion = "1.0.0"; // Specify the version of the chart you wish to deploy. const chartRepo = "https://your-helm-chart-repository.com"; // The URL to your Helm chart repository. // If your Helm chart and its repository are public, you can use its URL directly without additional configuration. // Create a Chart resource for the Angular application, using the Helm Chart. const angularChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo, }, // The namespace where you want to deploy your chart. It should be an existing namespace. namespace: "your-openshift-namespace", }); // Export the base URL inference from the Service endpoint if available. export const appUrl = angularChart.getResourceProperty("v1/Service", `${chartName}-your-service`, "status") .apply(status => status?.loadBalancer?.ingress[0]?.ip || status?.loadBalancer?.ingress[0]?.hostname);

    Make sure that the variable values for chartName, chartVersion, chartRepo, and namespace are correctly set to match your Helm chart and OpenShift cluster.

    In this program, we're doing the following:

    • Import the Kubernetes package from Pulumi, which is necessary to interact with Kubernetes resources.
    • Define variables for the chart name, version, and repository, which should be customized to point to the Angular Helm chart you want to deploy. The namespace should be updated to the one where the chart will be deployed on your OpenShift cluster.
    • Instantiate a new Helm chart in the cluster using the k8s.helm.v3.Chart resource. We provide configuration settings such as the chart name, version, and repository options.
    • Optionally, export the inferred base URL of the application, assuming the Helm chart creates a Kubernetes Service object that can be used to access the application. Adjust the getResourceProperty() call to match the name of the service as defined in the Helm chart.

    To use this program, save it in a file called index.ts, and run pulumi up to deploy the Helm chart onto your OpenShift cluster.

    Remember, the actual deployment to OpenShift will depend on the specifics of the Angular Helm chart you're using, and you may need to provide additional configuration (through values or other fetchOpts) specific to that chart or to your OpenShift environment.
