1. Deploy the gitpod-selfhosted helm chart on Digital Ocean Kubernetes Service


    To deploy the gitpod-selfhosted Helm chart on DigitalOcean Kubernetes Service (DOKS), you'll need to follow a few steps:

    1. Setup DigitalOcean Kubernetes Cluster: First, we'll create a cluster on DigitalOcean, which provides managed Kubernetes clusters.

    2. Install Helm Chart: Next, we'll deploy the Gitpod self-hosted Helm chart onto our Kubernetes cluster.

    Here's an overview of how we will use Pulumi to accomplish these tasks:

    • digitalocean.KubernetesCluster: We will instantiate a Kubernetes cluster in DigitalOcean using the digitalocean.KubernetesCluster resource. This Pulumi resource allows us to define the configuration for a DOKS cluster, such as the region, version, and node pool configuration.

    • kubernetes.helm.v3.Chart: After the cluster is up and running, we will deploy the gitpod-selfhosted Helm chart using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource handles installing and updating Helm charts within a Kubernetes cluster.

    Below is the TypeScript program that uses Pulumi to create the resources. This example assumes that Pulumi and node.js have been installed, the Pulumi CLI has been configured with DigitalOcean access token, and you have a Helm chart repository where the gitpod-selfhosted chart is hosted.

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a new DigitalOcean Kubernetes cluster with default settings. // Adjust the settings such as the region, version, and node count to suit your requirements. const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: '1.21.5-do.0', // Replace with a supported version in the DOKS. nodePool: { name: 'default-pool', size: 's-1vcpu-2gb', // This is the smallest node size, select based on requirements. nodeCount: 2, // Adjust node count according to your needs. }, }); // Create a provider for deploying Helm charts into the created cluster. const k8sProvider = new k8s.Provider('do-k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the gitpod-selfhosted Helm chart into the cluster. // You'll need to replace 'repo_url_here' with the URL of your Helm repo. const gitpodChart = new k8s.helm.v3.Chart('gitpod-selfhosted', { chart: 'gitpod', version: '0.6.0', // Specify the version of Gitpod you want to deploy. fetchOpts: { repo: 'repo_url_here', // Specify your Helm chart repository URL here. }, values: { // Provide any custom configuration values here, as key-value pairs. }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the Gitpod URL. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const gitpodUrl = pulumi.interpolate`http://${cluster.endpoint}`;

    The digitalocean.KubernetesCluster resource is configured with a node pool that specifies the size and count of nodes in your cluster. Adjust these settings to fit your resource needs or scaling requirements.

    The k8s.helm.v3.Chart represents the Helm chart we want to deploy. You need to specify the chart name, version, and the values for any custom settings. This example uses placeholder values for the chart version and repository - make sure to replace these with the actual chart details.

    To apply this Pulumi program, save the code to a file named index.ts, and run the following commands:

    pulumi up

    Pulumi will provision the resources on DigitalOcean and apply the Helm chart to your Kubernetes cluster. Once it's done, you'll get an output showing the kubeconfig and the Gitpod URL. You can use the kubeconfig to interact with the Kubernetes cluster using kubectl and access Gitpod at the URL provided.

    Remember, when dealing with cloud resources, you will incur costs. Be sure to delete the resources when you are done by running:

    pulumi destroy
