1. Deploy the teleport-ent-proxy helm chart on Opensshift


    Deploying a Helm chart on an OpenShift cluster with Pulumi is a task that involves multiple steps. First, you need to set up a Kubernetes provider pointing to your OpenShift cluster, and then you can deploy the Helm chart using Pulumi's Kubernetes provider and Chart resource.

    Before we start, make sure you have access to an OpenShift cluster, and you've configured kubectl to communicate with it. Pulumi uses the kubectl configuration to interact with your Kubernetes cluster.

    Let me walk you through a Pulumi program written in TypeScript, which deploys the teleport-ent-proxy Helm chart on OpenShift. The Chart resource from the @pulumi/kubernetes package is the main component of this deployment. It allows Pulumi to install, upgrade, and manage Helm charts in a Kubernetes cluster.

    Below is a Pulumi program that illustrates how to deploy a Helm chart to OpenShift:

    import * as k8s from "@pulumi/kubernetes"; // Define the OpenShift provider using the default kubeconfig credentials // This assumes that you have already configured kubectl to point to your OpenShift cluster const openshiftProvider = new k8s.Provider("openshift", { kubeconfig: process.env.KUBECONFIG, }); // Deploy the teleport-ent-proxy Helm chart to the OpenShift cluster const teleportEntProxyChart = new k8s.helm.v3.Chart("teleport-ent-proxy-chart", { repo: "teleport", // The Helm repository where the chart is located chart: "teleport-ent-proxy", // The name of the chart version: "x.y.z", // Replace x.y.z with the version of the chart you want to deploy // Here you can add custom values or override the chart values values: { // Please replace these values with the actual values you want to override key1: "value1", key2: "value2", }, }, { provider: openshiftProvider }); // Make sure to pass the provider we created above // To make the URL to access the deployed Helm release available as a stack output export const teleportEntProxyUrl = teleportEntProxyChart.getResourceProperty( "v1/Service", "teleport-ent-proxy-chart", // This name may vary depending on the chart and release names "spec" ).apply(spec => spec?.clusterIP); // We are assuming that the chart creates a Service with a clusterIP

    In the program above, we first import the necessary Kubernetes package from Pulumi. We create a Kubernetes provider, openshiftProvider, configured with the correct kubeconfig that allows Pulumi to talk to the OpenShift API server.

    Next, we create a Helm chart resource, teleportEntProxyChart, pointing to the teleport-ent-proxy chart in the specified Helm repository. Note that repo should be the name of the repository where the teleport chart is hosted, and chart the name of the Helm chart to install. You should replace "x.y.z" with the exact version of the chart you wish to deploy. Also, replace key1, key2, etc., with the actual Helm values you wish to override or specify.

    Lastly, we export a stack output, teleportEntProxyUrl, which can be used to obtain the URL at which the teleport-ent-proxy service is accessible within the cluster. This assumes that the Helm chart creates a Kubernetes Service with a clusterIP. If your chart exposes an external endpoint, you may need to adjust the property you're retrieving accordingly.

    Make sure you have the @pulumi/kubernetes package installed in your project:

    npm install @pulumi/kubernetes

    To run this Pulumi program, save it to a file (e.g., index.ts), then execute the Pulumi CLI commands to create a new stack and deploy your infrastructure:

    pulumi stack init <stack-name> pulumi up

    Replace <stack-name> with a name for your stack. The pulumi up command will perform the deployment and provide you with the outputs defined in the program, such as teleportEntProxyUrl in this case.

    Always refer to the Helm chart's documentation for the specific configuration values it accepts and the resources it creates, as the details can vary between charts.
