1. Deploy the turborepo-remote-cache helm chart on Linode Kubernetes Engine


    Deploying a Helm chart to a Kubernetes cluster involves several steps. First, you need to set up the Kubernetes cluster itself. In this case, we'll assume that the Linode Kubernetes Engine (LKE) cluster is already set up and configured, and you have the kubeconfig file available to interact with it.

    Next, we'll use Pulumi to deploy the Helm chart turborepo-remote-cache onto this LKE cluster. To achieve this, we'll be using the kubernetes package from Pulumi which provides us with the Chart resource - this resource allows us to deploy Helm charts.

    The following program demonstrates how to use Pulumi with TypeScript to deploy the turborepo-remote-cache helm chart on an existing LKE cluster:

    import * as k8s from "@pulumi/kubernetes"; // Make sure to set the KUBECONFIG environment variable or specify your kubeconfig file location. // This will be used by Pulumi to interact with your Kubernetes cluster. const kubeconfig = process.env.KUBECONFIG; // Create a Kubernetes provider instance using the kubeconfig const provider = new k8s.Provider("lke", { kubeconfig: kubeconfig, }); // Define the Helm chart for turborepo-remote-cache const turborepoRemoteCacheChart = new k8s.helm.v3.Chart("turborepo-remote-cache", { // You can specify the repo here if the chart is not in the default Helm chart repositories // repo: "https://your-chart-repo/", chart: "turborepo-remote-cache", // Below you may specify a version and any custom values. For this example, // we assume that Helm will pick the latest version and the default values are fine. // version: "1.0.0", // values: {}, // You can define chart-specific values here }, { provider }); // Export the resources created export const chartName = turborepoRemoteCacheChart.metadata.apply(meta => meta.name);

    In the code above:

    • We import the Pulumi Kubernetes package which includes the necessary components to interact with Kubernetes, including deploying Helm charts.
    • We create a Pulumi Kubernetes provider instance, which uses your existing kubeconfig for authentication with the LKE cluster.
    • We create a new Helm chart resource for the turborepo-remote-cache chart. The Chart resource is used launch Helm charts into a Kubernetes cluster using Pulumi. We assign it a name "turborepo-remote-cache" to identify it in our Pulumi stack.
    • Finally, we export the name of the Helm chart as a stack output. This can be helpful for querying or updating the Helm release later.

    Please note that for this code to work, you need to have Pulumi installed and configured to use your preferred cloud provider, in this case, Linode. You should also have Helm installed on the machine running this Pulumi program, and the Helm chart for turborepo-remote-cache should be available in the Helm repository specified or via the default Helm chart repositories. If the Helm chart lies in a private repository, you will have to add the repo property and potentially include the repository's credentials.

    To run this Pulumi program, you would execute pulumi up in the directory containing the above code. This will prompt Pulumi to begin provisioning the resources as described. If it is your first time running Pulumi in this directory, you will be prompted to create a new Pulumi project and stack.

    Always make sure that you review the Helm chart values and adjust them according to your requirements before deploying it into your cluster. You can specify these values within the values field in the Chart resource arguments.
