1. Deploy the gitpod-selfhosted helm chart on Rancher


    To deploy the Gitpod self-hosted Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you'll need to follow several steps. First, you'll have to ensure that you have access to a Rancher-managed Kubernetes cluster. Then, you'll use Pulumi with the Kubernetes provider to install the Gitpod Helm chart.

    Below is a Pulumi TypeScript program that demonstrates how to deploy the Gitpod self-hosted Helm chart on a Rancher-managed Kubernetes cluster. This program assumes that you've already configured Rancher and Pulumi with the necessary access credentials for the target Kubernetes cluster.

    1. Import Dependencies: We start by importing the necessary Pulumi and Kubernetes packages.
    2. Create a Kubernetes Provider: Set up the Kubernetes provider to interact with the Rancher-managed cluster.
    3. Deploy the Helm Chart: Use the Chart resource from the Pulumi Kubernetes provider to deploy the Gitpod self-hosted Helm chart.

    Here's the Pulumi program in TypeScript:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Instantiate a Kubernetes provider configured with access to your Rancher Kubernetes cluster. // Replace `kubeconfig` value with your actual kubeconfig file or its content. const rancherK8sProvider = new k8s.Provider('rancher-k8s-provider', { kubeconfig: '<your-kubeconfig-here>', }); // Set the namespace where you want to deploy Gitpod. const namespace = new k8s.core.v1.Namespace('gitpod', { metadata: { name: 'gitpod', }, }, { provider: rancherK8sProvider }); // Deploy the Gitpod helm chart using the `Chart` resource. const gitpodChart = new k8s.helm.v3.Chart('gitpod-helm-chart', { chart: 'gitpod', version: '0.10.0', // Replace with the version you wish to deploy namespace: namespace.metadata.name, // Use the created namespace fetchOpts: { repo: 'https://charts.gitpod.io', // The Gitpod Helm chart repository }, // Define any custom values.yaml settings here that you want to override. values: { hostname: 'gitpod.your-domain.com', // Replace with your Gitpod instance hostname // Additional Gitpod settings can be added here. }, }, { provider: rancherK8sProvider }); // Export the name of the namespace export const gitpodNamespace = namespace.metadata.name;

    In this program:

    • We import the Pulumi SDK and Kubernetes package which are necessary to interact with Kubernetes resources.
    • We create a Kubernetes provider instance that Pulumi uses to communicate with your Rancher-managed Kubernetes cluster via the given kubeconfig.
    • We create a Kubernetes namespace for Gitpod to keep its resources separate from other applications on the cluster.
    • We deploy Gitpod using its Helm chart. You will need to set the hostname to the domain where you want to access Gitpod. If you have specific values you want to override from the chart's default values.yaml file, provide them in the values property.
    • Finally, we export the namespace name that might be useful if you want to reference it in subsequent Pulumi programs or configurations.

    Please replace placeholders (<...>) with the actual values pertinent to your setup, like kubeconfig. Also, customize the values within the values property as per your requirements for Gitpod. The version of Gitpod's Helm chart (0.10.0) should also be confirmed for the latest or your desired version before deploying it. Ensure the Rancher cluster is ready to accept these deployments, and you have applied any necessary configurations such as setting up your domain name to resolve to the ingress controller's IP address.

    Once the program is ready, you would run it using the Pulumi CLI in the following manner:

    pulumi up

    This command initializes the deployment, which Pulumi performs according to your program. If it's the first time you're running this command, Pulumi will prompt you to create a new stack, which is an isolated environment for your project. After reviewing the proposed changes, you can proceed to confirm the deployment by selecting "yes" when prompted.
