1. Deploy the ignite helm chart on Linode Kubernetes Engine


    To deploy the Ignite Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, we'll follow these steps:

    1. Set up a new Pulumi TypeScript project, if you don't have one already.
    2. Install the Pulumi Kubernetes provider, which allows you to interact with Kubernetes resources including Helm charts.
    3. Write the Pulumi code to provision an LKE cluster and deploy the Ignite Helm chart to it.

    Firstly, you would need to have Pulumi CLI installed and configured for use with Linode. For Linode Kubernetes Engine, you need to set up the Linode CLI and create a Kubernetes cluster. Then, you'll use kubectl to get credentials for your Kubernetes cluster so that Pulumi can manage resources on it.

    Now let's write the Pulumi program. I'm going to provide you with a minimal TypeScript program that accomplishes this task.

    Before running this code, ensure you have the following prerequisites:

    • Pulumi CLI installed and set up.
    • Linode CLI installed and a Kubernetes cluster created.
    • kubectl configured to interact with your Linode Kubernetes cluster.
    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses our existing cluster. const clusterProvider = new k8s.Provider("lkeCluster", { kubeconfig: "<Your Linode Kubeconfig Here>", // Replace this with your Linode cluster's kubeconfig. }); // Deploy the Ignite Helm chart. const igniteChart = new k8s.helm.v3.Chart("ignite-chart", { chart: "ignite", // It's good to check the Helm repository for any specific values you want to override. // The typical structure is a nested object like below (these are hypothetical values): // values: { // service: { // type: "ClusterIP", // }, // }, // This example assumes the Ignite Helm chart is available in the default repositories. // If not, you might need to add 'repo' and 'version' properties to specify its location. // For example: // repo: "http://example.com/charts", // version: "1.2.3", }, { provider: clusterProvider }); // Export the URL for the deployed application (if it's publicly accessible). // This line might need to be adapted depending on how Ignite exposes its services. export const igniteUrl = igniteChart.getResourceProperty("v1/Service", "ignite-chart-ignite", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Replace <Your Linode Kubeconfig Here> with the actual kubeconfig of your Linode Kubernetes Cluster. This kubeconfig is used to create a k8s.Provider resource, which knows how to communicate with your Kubernetes cluster.

    This small Pulumi program deploys an Ignite Helm chart using Pulumi's Kubernetes (@pulumi/kubernetes) package.

    Please note that more specific configuration may be required for the Ignite chart. Check the official Helm chart for any values that you can customize for your deployment, such as resource limits or service configuration.

    The last part of the script attempts to export the external URL of the Ignite deployment. Depending on the service type and your ingress configuration, you might need to adjust this to correctly reflect how to access Ignite.

    To run the program, you will need to navigate to the directory of your Pulumi project in a terminal, and then execute the following command:

    pulumi up

    This command triggers the deployment process, where Pulumi will review your code, present you with a summary of the planned changes and ask for confirmation before proceeding to make those changes in your Linode Kubernetes cluster.
