1. Deploy the snyk-exporter helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the snyk-exporter Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, we will need to follow these steps:

    1. Set up a new Pulumi project: If you haven't already, you'll need to create a new Pulumi project for your Kubernetes infrastructure.
    2. Configure Pulumi for Linode: You have to set up the appropriate cloud provider configuration for Pulumi to interact with Linode.
    3. Provision a Kubernetes Cluster on LKE: Deploy a Kubernetes cluster on Linode Kubernetes Engine.
    4. Deploy the Helm Chart: Install the snyk-exporter Helm chart on the provisioned Kubernetes cluster.

    For these steps, we will be using the Pulumi Kubernetes provider to interact with Kubernetes and perform operations like creating a cluster and deploying Helm charts.

    Now let's proceed with the deployment. Below is a complete Pulumi program in TypeScript, which will create a new Linode Kubernetes cluster and deploy the snyk-exporter Helm chart. Please ensure that you have installed Pulumi CLI and set up your Linode API token according to the Pulumi Linode provider documentation.

    import * as linode from "@pulumi/linode"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Provision a new Linode Kubernetes Engine cluster const cluster = new linode.LkeCluster("my-cluster", { label: "my-cluster", k8sVersion: "1.20", region: "us-central", pools: [{ type: "g6-standard-2", count: 3, // Number of nodes in the node pool }], }); // Step 2: Configure the Kubernetes provider to use the kubeconfig from the Linode cluster const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig, }); // Step 3: Deploy the snyk-exporter helm chart const chart = new kubernetes.helm.v3.Chart("snyk-exporter", { chart: "snyk-exporter", // The name of the helm chart version: "1.0.0", // Specify the version of the chart you want to deploy // Add the repository where the chart is located if it's not in the default helm repo repositoryOpts: { repo: "https://charts.helm.sh/stable", }, // If you have specific values you want to override in the chart, specify them here values: { service: { type: "LoadBalancer", }, }, }, { provider: k8sProvider }); // Export the endpoint of the snyk-exporter service export const snykExporterServiceEndpoint = chart.getResourceProperty("v1/Service", "snyk-exporter-snyk-exporter", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Here's a rundown of what each section of the code is doing:

    • We import the necessary linode and kubernetes modules from Pulumi's package collection.
    • We set up the LKE cluster with the desired Kubernetes version, region, and size and number of nodes.
    • We retrieve the kubeconfig file for the newly created cluster, which is needed to communicate with the cluster.
    • We create a new Provider resource, which represents the interface to the Kubernetes cluster.
    • With the Helm Chart resource kubernetes.helm.v3.Chart, we install the snyk-exporter chart, passing in any overridden values you'd like to specify.
    • Finally, we export the IP address of the snyk-exporter service, which can be used to access the deployed application.

    To execute this program:

    1. Save the code in a file named index.ts.
    2. Run pulumi up from the command line in the same directory as your index.ts file. This will start the Pulumi deployment process.
    3. Follow the prompts from Pulumi to preview and confirm the deployment.

    Please remember to replace the chart, version, and repo fields with the actual values corresponding to the snyk-exporter chart if they are different from the placeholders provided.

    Once the deployment is successful, Pulumi will output the service endpoint which you can use to interact with the snyk-exporter deployment.
