1. Deploy the dnation-kubernetes-monitoring-stack helm chart on Linode Kubernetes Engine


    To deploy the dnation-kubernetes-monitoring-stack Helm chart on Linode Kubernetes Engine using Pulumi, we will follow these steps:

    1. Set Up the Kubernetes Cluster: We'll start by provisioning a Kubernetes cluster on Linode using Linode's Terraform provider, as Pulumi does not have a native Linode provider at the time of this writing. However, Pulumi can interoperate with Terraform providers to fill this gap.

    2. Install the Helm Chart: Once we have access to the Kubernetes cluster, we'll install the Helm chart for dnation-kubernetes-monitoring-stack using Pulumi's Kubernetes provider.

    Here is a step-by-step program written in TypeScript to accomplish the task:

    import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; import * as linode from "@linode/terraform-provider-linode"; // Configure Linode provider const linodeProvider = new linode.Provider("linode", { token: "YOUR_LINODE_API_TOKEN", // Replace with your Linode API token }); // Provision a LKE (Linode Kubernetes Engine) cluster const cluster = new linode.LkeCluster("my-lke-cluster", { k8sVersion: "1.20", // Specify your desired Kubernetes version region: "us-central", // Specify your desired region tags: ["pulumi-lke"], pool: [{ type: "g6-standard-2", // This is the type of node in Linode's terminology count: 2, // Number of nodes in the node pool }], }, { provider: linodeProvider }); // Wait for the kubeconfig to become available and create a K8s provider instance using it const k8sProvider = pulumi.all([cluster.id, cluster.kubeconfig]).apply(([_, kubeconfig]) => { return new k8s.Provider("lke-k8s", { kubeconfig: kubeconfig, }); }); // Deploy the dnation-kubernetes-monitoring-stack Helm chart const monitoringChart = new k8s.helm.v3.Chart("dnation-monitoring-stack", { chart: "dnation-kubernetes-monitoring-stack", version: "1.0.0", // Specify the version of the chart you want to deploy fetchOpts: { repo: "https://dnationcloud.github.io/helm-hub/", // The Helm repository URL }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and endpoint export const kubeconfig = cluster.kubeconfig; export const endpoint = pulumi.interpolate`${cluster.apiEndpoints[0].endpoint}`;


    • We first import the necessary Pulumi modules (@pulumi/kubernetes, @pulumi/pulumi) and the @linode/terraform-provider-linode module to interact with Linode's services.

    • We then set up the Linode provider with your Linode API token. Make sure to replace "YOUR_LINODE_API_TOKEN" with your actual API token. This provider is used to communicate your intentions to Linode.

    • We provision a new LKE cluster with the specified Kubernetes version and node specifications. You may adjust the k8sVersion, region, type, and count to match your requirements.

    • The k8sProvider is created using the kubeconfig provided by the newly created LKE cluster, which Pulumi uses to interact with the Kubernetes cluster.

    • With the Kubernetes provider configured, we create a new Helm chart resource, monitoringChart, which installs the dnation-kubernetes-monitoring-stack Helm chart from the provided repository URL.

    • Finally, we export the kubeconfig and the Kubernetes API endpoint for the LKE cluster. These can be used to interact with the cluster using kubectl or other Kubernetes tooling outside of Pulumi.

    To set up Pulumi with Linode, your Pulumi stack configuration must contain the Linode API token, and you should have kubectl installed on your local machine to interact with the cluster. You would run this Pulumi program using Pulumi CLI commands such as pulumi up to create the resources. Remember, this code assumes you already have Pulumi set up with the appropriate credentials for Linode and the @linode/terraform-provider-linode installed.
