1. Deploy the dex-controller helm chart on Kubernetes


    To deploy the dex-controller Helm chart on Kubernetes using Pulumi, you'll need to have:

    1. A Kubernetes cluster already provisioned and configured to communicate with your Pulumi program.
    2. The Helm CLI installed locally, as Pulumi uses it under the hood to deploy Helm charts.

    Here is what you will do in the Pulumi program:

    • Import necessary packages: We will import the @pulumi/kubernetes package which provides the Kubernetes resource provider necessary to interact with Kubernetes resources. Also, we will need @pulumi/pulumi for core Pulumi functionalities.
    • Create the Helm chart resource: Using the Chart resource from the @pulumi/kubernetes/helm/v3 module, we will deploy the dex-controller Helm chart into the Kubernetes cluster.

    Now, let's write the code to deploy the dex-controller Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Initialize to use the existing Kubernetes cluster context. const cluster = new k8s.Provider("k8s-provider", { kubeconfig: pulumi.output(k8s.core.v1.Config.decode(pulumi.config.requireSecret("kubeconfig"))).apply(JSON.stringify), }); // Deploy the dex-controller Helm chart into the Kubernetes cluster. const dexControllerChart = new k8s.helm.v3.Chart("dex-controller", { chart: "dex-controller", // Replace with the repository where the dex-controller chart is located. // For instance, if the dex-controller chart is in the stable repository, use `https://charts.helm.sh/stable` // Set the version of dex-controller if needed. version: "chart-version", // specify the chart version fetchOpts: { repo: "https://charts.example.com/", // replace with the URL of the chart repository }, values: { // Provide configuration values for the dex-controller chart. // These values are dependent on the specific chart you are deploying. // Check the documentation for the chart for the available options. }, }, { provider: cluster }); // Export the endpoint of the dex-controller if it creates a service with a LoadBalancer or similar. export const dexEndpoint = dexControllerChart.getResourceProperty("v1/Service", "dex-controller", "status") .apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);

    In the above code, make sure to:

    • Replace chart-version with the version number of the dex-controller Helm chart you desire to install.
    • Replace https://charts.example.com/ with the URL of the Helm chart repository where the dex-controller chart is hosted.
    • Fill in the values field with the necessary configuration for the dex-controller Helm chart. Helm chart values are specific to each chart and define the configurable parameters that apply to the deployment. Check the dex-controller chart's documentation for the values you can customize.
    • Replace the "kubeconfig" reference with the actual way you are getting the kubeconfig information if not from Pulumi config.

    With this code, Pulumi will handle the deployment of the dex-controller Helm chart using the current Kubernetes context as specified in your Pulumi stack configuration. If your chart exposes a service with a LoadBalancer, the dexEndpoint export will provide you with the external endpoint that you can use to interact with the dex-controller.
