1. Deploy the puppetdb helm chart on Kubernetes

    TypeScript

    To deploy the PuppetDB Helm chart on Kubernetes using Pulumi, we will use the kubernetes.helm.sh/v3.Chart resource from the Kubernetes provider. This resource allows you to deploy applications packaged as Helm charts into a Kubernetes cluster.

    The program below will deploy the PuppetDB Helm chart. Before proceeding with the code, ensure that you have:

    1. Pulumi CLI installed
    2. Kubernetes cluster running and kubectl configured to connect to your cluster
    3. Helm CLI installed, and the PuppetDB Helm chart available in one of your Helm repositories

    Here’s a step-by-step explanation of the program:

    • Import the Package: We begin by importing the Kubernetes package which is required to interact with your Kubernetes cluster.
    • Create a Chart Resource: Instantiate a new Helm chart resource using new kubernetes.helm.v3.Chart. The parameters include the chart name (you may need to reference the correct chart name from your Helm repository), the chart version, and any values you want to override in the default chart configuration.

    Now, let's proceed with the Pulumi TypeScript program that deploys PuppetDB using its Helm chart:

    import * as kubernetes from "@pulumi/kubernetes"; const puppetdbChart = new kubernetes.helm.v3.Chart("puppetdb", { chart: "puppetdb", version: "x.x.x", // specify the exact chart version fetchOpts: { repo: "https://example.com/helm-repo/", // replace with the PuppetDB Helm repo URL }, // Uncomment the following if you need to override default values /* values: { // Specify any custom chart values here, for example: // storageClass: "my-storage-class", // replicaCount: 3, }, */ }); // Optionally, you may want to export a value from the deployed chart, like a service URL or IP export const puppetdbServiceUrl = puppetdbChart.getResourceProperty("v1/Service", "<service-name>", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    After defining the puppetdbChart object above, we create an instance of the chart with the specified options. Make sure to replace "x.x.x" with the actual version number of the PuppetDB Helm chart you want to deploy and "https://example.com/helm-repo/" with the actual URL of the PuppetDB Helm chart repository.

    If you need to override the default chart values, uncomment the values field and specify the necessary parameters. For instance, if you want to specify a custom storage class or change the number of replicas.

    Finally, we export a sample value, puppetdbServiceUrl, which is the URL endpoint of the deployed PuppetDB Service. Replace "<service-name>" with the name of the service created by the PuppetDB chart.

    To deploy this to your Kubernetes cluster, save the code in a file with a .ts extension, and then run the following commands:

    pulumi up

    This command instructs Pulumi to perform an update, creating or updating resources as needed to match the desired state defined in your code. As part of its output, you’ll see any stack exports you've defined, like puppetdbServiceUrl.

    Once you no longer need the deployed resources, you can remove them using the below command:

    pulumi destroy

    This will tear down all resources managed by Pulumi.
