1. Deploy the stackdriver-metrics-adapter helm chart on Linode Kubernetes Engine


    To deploy the stackdriver-metrics-adapter Helm chart on a Linode Kubernetes Engine (LKE) cluster using Pulumi, you'll need to follow these steps:

    1. Set up a Linode Kubernetes Cluster: Before deploying any applications using Helm, you need a Kubernetes cluster. You can provision one on Linode using Pulumi's Linode provider.

    2. Install the stackdriver-metrics-adapter Helm Chart: Helm charts are packages that contain all of the necessary resources to run an application, tool, or service inside a Kubernetes cluster. To manage Helm charts with Pulumi you can utilize the @pulumi/kubernetes library, more specifically the helm.v3.Chart resource.

    Here's a detailed program written in TypeScript that demonstrates these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as linode from "@pulumi/linode"; // Step 1: Create a new Linode Kubernetes Engine (LKE) cluster const cluster = new linode.LkeCluster("my-lke-cluster", { region: "us-central", k8sVersion: "1.20", label: "my-lke-cluster", tags: ["pulumi-demo"], pool: { count: 3, type: "g6-standard-2", }, }); // Step 2: Configure the Kubernetes provider to connect to the LKE cluster const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the stackdriver-metrics-adapter Helm chart const stackdriverMetricsAdapterChart = new kubernetes.helm.v3.Chart( "stackdriver-metrics-adapter", { chart: "stackdriver-metrics-adapter", version: "TODO:SpecifyChartVersion", // Replace with the desired chart version fetchOpts: { repo: "TODO:SpecifyRepositoryUrl", // Replace with the repository URL where the chart is located }, // Include any custom values for the Helm chart here values: { // For example, you might want to specify Stackdriver project ID: // stackdriverProjectID: "{YOUR_PROJECT_ID}", }, }, { provider: k8sProvider } ); // Export the cluster's kubeconfig and the service endpoint of the stackdriver-metrics-adapter export const kubeconfigOutput = kubeconfig; export const stackdriverMetricsAdapterEndpoint = stackdriverMetricsAdapterChart.getResourceProperty( "v1/Service", "stackdriver-metrics-adapter", "status" ).apply(status => status.loadBalancer.ingress[0].ip);

    Here's what each part of the program does:

    • Linode Kubernetes Cluster: We create a new LKE cluster with the linode.LkeCluster resource. We specify the region, Kubernetes version, label, and configuration for the node pool (in this case, consisting of 3 nodes of the "g6-standard-2" type).

    • Kubernetes Provider Configuration: Pulumi needs to know how to connect to the new Kubernetes cluster. The .kubeconfig generated by Linode is used to set up a kubernetes.Provider. This kubeconfig provides the necessary credentials to connect and manage the cluster.

    • Stackdriver Metrics Adapter Helm Chart: We deploy the stackdriver-metrics-adapter Helm chart using Pulumi's helm.v3.Chart resource. You must replace the version and repo with the actual version and repository of the Stackdriver Metrics Adapter chart. You can also include custom values to configure the chart to your needs.

    Lastly, we export the kubeconfig so you can interact with the Kubernetes cluster using tools like kubectl. We also export the IP address for the stackdriver-metrics-adapter service, assuming it's exposed via a LoadBalancer on your LKE cluster.

    Remember to replace placeholders like TODO:SpecifyChartVersion and TODO:SpecifyRepositoryUrl with actual values before running the Pulumi program.

    After you save this program as index.ts, you can run it using the Pulumi CLI:

    pulumi up

    This command will prompt you to confirm the actions before performing them. Once confirmed, Pulumi will carry out the necessary steps to provision your infrastructure and deploy the Helm chart as described in the program.
