1. Deploy the sloth helm chart on Linode Kubernetes Engine


    Deploying a Helm chart on a Kubernetes cluster can be streamlined using Pulumi's Kubernetes provider. Specifically, the kubernetes.helm.v3.Chart resource is designed to enable users to deploy Helm charts to a Kubernetes cluster.

    In this case, we'll do the following:

    1. Set up Linode Kubernetes Engine (LKE) cluster using Linode provider.
    2. Use Pulumi Kubernetes provider to install the "sloth" Helm chart on the LKE cluster.

    Before running the code, you should have Pulumi CLI installed and configured with access tokens for Linode and Kubernetes.

    Here is how you can accomplish the deployment:

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // This example assumes that you have Linode API access already set up. // Create a new Linode Kubernetes Engine (LKE) cluster. const cluster = new linode.LkeCluster("my-cluster"), { k8sVersion: "1.21", // Use an appropriate Kubernetes version available in LKE here. region: "us-east", // Set the region where you want to deploy your cluster. pool: { type: "g6-standard-2", count: 3, // Adjust the number of nodes in the cluster as per your requirements. }, }); // Export the Kubeconfig. export const kubeconfig = cluster.kubeconfig; // Set up the Kubernetes provider using the generated kubeconfig from the LKE cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig.apply(JSON.stringify), }); // Deploy the "sloth" Helm chart to the Linode Kubernetes cluster. const slothChart = new k8s.helm.v3.Chart("sloth", { chart: "sloth", // Specify any values to override in the Helm chart here. // For example: values: { image: { tag: "latest" } }, fetchOpts:{ // Normally you would have your repo added here, this is a placeholder. // repo: "https://charts.example.com/", }, }, { provider: k8sProvider }); // Export the Helm chart name and status as outputs export const slothStatus = slothChart.status; export const slothName = slothChart.getResourceName();

    In this code:

    • We first define an LKE cluster with the desired configurations, including Kubernetes version, region, and node count.
    • We then export the Kubeconfig which will be used by the Kubernetes provider to interact with the cluster.
    • We set up the Kubernetes provider with the cluster Kubeconfig.
    • Lastly, we deploy the "sloth" Helm chart into our Kubernetes cluster.

    Once you have this code in a .ts file, you can deploy it using Pulumi by running:

    pulumi up

    Pulumi will then execute the code and provide you with a detailed summary of the actions to be taken. Confirm the actions by proceeding with the provided prompt. After deployment, you will receive outputs for your Kubeconfig, Helm chart name, and status, which can be used for your reference.

    Ensure that the appropriate Helm repository URL is known and replace the commented repo placeholder in the fetchOpts with the actual URL for the "sloth" Helm chart repository. If you need a specific version of the chart or want to override default values, provide additional parameter settings in the values attribute.
