1. Deploy the kube-httpcache helm chart on Kubernetes


    To deploy the kube-httpcache Helm chart on a Kubernetes cluster using Pulumi, you can utilize the kubernetes.helm.v3.Chart class from the Pulumi Kubernetes provider. This class allows us to deploy Helm charts from various repositories or local Helm chart paths.

    Below is a Pulumi TypeScript program that demonstrates how to deploy the kube-httpcache Helm chart:

    1. First, you need to have a Kubernetes cluster. The program assumes you have a cluster configured and available to Pulumi via the kubeconfig file.
    2. We define a Helm chart resource, specifying the chart name (kube-httpcache), the chart version (if you want to pin to a specific version), and optionally the repository URL where the chart is hosted.
    3. We add optional configuration values if needed in the values field. These values should match the configurable parameters of the Helm chart.

    Here is the complete program that can be used to deploy the kube-httpcache Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Deploying the kube-httpcache Helm chart to a Kubernetes cluster. const kubeHttpCacheChart = new k8s.helm.v3.Chart("kube-httpcache", { chart: "kube-httpcache", // Uncomment the following line and specify the repository URL if it's not a stable Helm chart: // repo: "<repository-url>", // Replace `<version>` with the desired chart version, if you need to pin to a specific version: // version: "<version>", // Specify custom values for the Helm chart as needed: values: { // Add your custom values here, for example: // replicaCount: 2, // ... }, // Optional: specify the Kubernetes namespace if you want to deploy the chart in a specific namespace. // namespace: "<namespace>", }); // To access specifics about the deployed Helm chart, like its resources, you can query it: const deployedResources = kubeHttpCacheChart.resources;

    In the above code:

    • We import the @pulumi/kubernetes package, which contains the necessary modules for interacting with Kubernetes resources, including Helm charts.
    • We create a new Helm chart resource using the class k8s.helm.v3.Chart. We assign it a logical name kube-httpcache, which is used within Pulumi to refer to this resource.
    • The chart property specifies the Helm chart's name we wish to deploy—kube-httpcache.
    • Optionally, you would use repo to specify the chart repository's URL if the chart is not located in one of the default repositories that Helm is configured with.
    • If you want to pin to a specific version of the Helm chart, you can specify it using the version property.
    • You can customize the chart's deployment by setting custom values in the values field. These should align with the chart's available configuration options.
    • The namespace property is commented out, but you can specify a Kubernetes namespace if you wish to deploy the chart into a specific namespace other than the default.
    • Finally, we expose the resources created by the Helm chart deployment as deployedResources, which can be useful for querying or exporting.

    This Pulumi program can be placed in a file like index.ts. To run this index.ts, you'll use the Pulumi CLI:

    1. Navigate to the directory containing index.ts.
    2. Run pulumi up to create or update the resources as defined by the program.

    The CLI will show you a preview of the actions Pulumi is going to perform and, upon confirmation, will deploy the kube-httpcache Helm chart to your Kubernetes cluster.
