1. Deploy the zipkin-stackdriver-proxy helm chart on Linode Kubernetes Engine


    Deploying a Helm chart on a Kubernetes cluster can be approached as a two-step process. First, you need to provision the Kubernetes cluster, and second, deploy the Helm chart onto the cluster.

    For the Kubernetes cluster, I will use Linode as the cloud provider. Linode's Kubernetes Engine (LKE) is not directly supported as a Pulumi resource. However, you can create and manage a Linode Kubernetes Engine cluster using linode_kubernetes_cluster of the Linode Pulumi provider, which provides a straightforward way to create a managed Kubernetes cluster on Linode.

    Once the LKE cluster is up and running, you can deploy Helm charts to it. Pulumi's Kubernetes provider will interact with the cluster to deploy the Zipkin Stackdriver proxy using Helm. Unfortunately, as of my knowledge cutoff, Pulumi does not have a dedicated resource for deploying Helm charts on Linode Kubernetes Engine in their registry, but you can still use the Kubernetes provider and the helm.v3.Chart resource to deploy any standard Helm chart to the cluster.

    Below is a TypeScript program that sets up an LKE cluster and deploys the zipkin-stackdriver-proxy Helm chart to it. Make sure to install the necessary packages using npm or yarn before you run the program (@pulumi/linode, @pulumi/kubernetes, and @pulumi/pulumi).

    import * as pulumi from '@pulumi/pulumi'; import * as linode from '@pulumi/linode'; import * as k8s from '@pulumi/kubernetes'; // Create a Linode Kubernetes Engine (LKE) cluster. const cluster = new linode.KubernetesCluster('my-lke-cluster', { // Specify the region where you want to deploy your cluster. region: 'us-central', // Specify the Kubernetes version. k8sVersion: '1.20', // Define the node pools for your cluster. // Adjust the type and count of nodes as per your requirements. pools: [{ count: 1, type: 'g6-standard-2', }], }); // Export the kubeconfig so that the Kubernetes provider can use it. export const kubeconfig = cluster.kubeconfig; // Create an instance of the Kubernetes provider with the kubeconfig. const k8sProvider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig, }); // Deploy the zipkin-stackdriver-proxy Helm chart on the LKE cluster. const chart = new k8s.helm.v3.Chart('zipkin-stackdriver-proxy-chart', { chart: 'zipkin-stackdriver-proxy', // You might need to specify the repository where your Helm chart is located. // If needed, use `fetchOpts` to configure access to private Helm charts. fetchOpts: { repo: 'http://your-helm-chart-repository/', }, // Specify additional configuration values for your Helm chart. values: { // These values will depend on the Zipkin Stackdriver proxy Helm chart's requirements. // Replace these with actual values from your desired Helm chart's configuration. }, // Specify the namespace where the Helm chart should be deployed. // This is optional; if not set, it defaults to the 'default' namespace. namespace: 'default', }, { provider: k8sProvider }); // Export the endpoint to access the Zipkin Stackdriver proxy service. export const zipkinServiceEndpoint = chart.getResourceProperty('v1/Service', 'zipkin-stackdriver-proxy-service', 'status').apply(status => { if (status.loadBalancer?.ingress) { return status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname; } return 'Service not exposed externally'; });

    To execute this Pulumi program, you need to set up your Pulumi CLI and authenticate with Linode.

    Here’s a quick rundown of what each part of the program does:

    1. Import necessary modules from the Pulumi SDK.
    2. Create an LKE cluster with the specified configuration like region, Kubernetes version, and node pool settings.
    3. Export the kubeconfig.
    4. Instantiate the Kubernetes provider with the exported kubeconfig from the created LKE cluster.
    5. Deploy the zipkin-stackdriver-proxy Helm chart using the Kubernetes provider and the Helm package. This part assumes the Helm chart for the Zipkin Stackdriver proxy is publicly available or you provide the correct repository.
    6. Optionally, export the exposed service endpoint after the deployment, which allows you to access the Zipkin Stackdriver proxy outside the cluster.

    Remember to configure an authentication token for Linode in the Pulumi stack configuration before you run pulumi up to apply the deployment. You can manage your tokens in the Linode Cloud Manager under the "API Tokens" section.

    For specifics about the zipkin-stackdriver-proxy Helm chart values and the correct Helm repository URL, you'll need to refer to its documentation or repository.
