1. Deploy the gitpod-selfhosted helm chart on Linode Kubernetes Engine

    TypeScript

    Deploying a Helm chart on a Kubernetes cluster involves a few steps: setting up the cluster, installing the Helm CLI, and then using Helm to deploy the chart. When working with infrastructure as code, these steps can be codified using Pulumi. In this case, we'll focus on deploying the gitpod-selfhosted Helm chart to a Linode Kubernetes Engine (LKE) cluster.

    Here's how you can create a Linode Kubernetes Engine cluster and deploy the gitpod-selfhosted Helm chart on it using Pulumi with TypeScript:

    Set up Pulumi TypeScript Project

    To begin, make sure you have Pulumi CLI installed and the Linode provider configured with your Linode API token. If you haven't yet, you can follow the installation instructions in the Pulumi documentation.

    1. Start a new Pulumi project:

      pulumi new typescript
    2. Install necessary packages:

      Your Pulumi program will need the @pulumi/linode and @pulumi/kubernetes packages to create an LKE cluster and deploy Helm charts to it.

      npm install @pulumi/linode @pulumi/kubernetes

    With the Pulumi project set up and the necessary packages installed, you can now define your infrastructure.

    Define the LKE Cluster

    You'll start by defining a new Linode Kubernetes Engine cluster resource.

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a new LKE cluster. const cluster = new linode.LkeCluster("gitpod-cluster", { region: "us-central", // Choose the region that is suitable for you k8sVersion: "1.20", // Specify the desired Kubernetes version labels: ["gitpod"], tags: ["gitpod"], pool: [{ count: 3, // Number of nodes type: "g6-standard-2", // Node type (this is Linode's plan identifier for a 4GB node) }], });

    Set up Kubeconfig

    To interact with the newly created cluster, you'll need the Kubeconfig, which can be obtained from the LKE cluster resource once the cluster is up and running.

    // Export the Kubeconfig for the cluster export const kubeconfig = cluster.kubeconfig;

    Deploy Gitpod Helm Chart

    With the Kubernetes cluster ready and the Kubeconfig available, you can proceed to deploy the Gitpod Helm chart. This example deploys the chart from a hypothetical Helm repository. You'll need to replace "https://charts.gitpod.io" with the actual repository URL containing the gitpod-selfhosted Helm chart.

    // Create a new Kubernetes provider instance that uses our kubeconfig const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the gitpod-selfhosted Helm chart const gitpodChart = new k8s.helm.v3.Chart("gitpod-selfhosted", { chart: "gitpod-selfhosted", version: "0.10.0", // Replace with the correct chart version fetchOpts: { repo: "https://charts.gitpod.io" }, // Define values for the Helm chart as needed values: { components: { imageBuilder: { workspaceImages: { build: { nodeName: "gitpod", }, }, }, }, }, }, { provider: k8sProvider }); // Export the URL for the gitpod application export const gitpodUrl = pulumi.interpolate`http://${gitpodChart.getResourceProperty("v1/Service", "proxy", "status").apply(status => status.loadBalancer.ingress[0].ip)}`;

    Full Pulumi Program

    Combining the above parts, here is the full Pulumi program:

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a Linode Kubernetes Engine cluster const cluster = new linode.LkeCluster("gitpod-cluster", { region: "us-central", k8sVersion: "1.20", labels: ["gitpod"], tags: ["gitpod"], pool: [{ count: 3, type: "g6-standard-2", }], }); // Export the Kubeconfig export const kubeconfig = cluster.kubeconfig; // Kubernetes provider const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Gitpod Helm chart deployment const gitpodChart = new k8s.helm.v3.Chart("gitpod-selfhosted", { chart: "gitpod-selfhosted", version: "0.10.0", fetchOpts: { repo: "https://charts.gitpod.io" }, values: { components: { imageBuilder: { workspaceImages: { build: { nodeName: "gitpod", }, }, }, }, }, }, { provider: k8sProvider }); // Output the Gitpod URL export const gitpodUrl = pulumi.interpolate`http://${gitpodChart.getResourceProperty("v1/Service", "proxy", "status").apply(status => status.loadBalancer.ingress[0].ip)}`;

    Run pulumi up to provision the resources and deploy the Gitpod Helm chart on Linode Kubernetes Engine.

    This program creates a Kubernetes cluster on Linode with the necessary node count and instance types. It then uses the Kubernetes provider to interact with the cluster and deploys the gitpod-selfhosted Helm chart to the cluster.

    Note that the values section in the chart deployment is placeholder content; you will need to modify it according to the actual requirements of the Gitpod Helm chart and your desired Gitpod configuration.

    Lastly, the program exports the Gitpod URL using the ingress IP address, which you can use to access your Gitpod installation once it's running.
