1. Deploy the lighthouse-jx helm chart on Digital Ocean Kubernetes Service


    Deploying a Helm chart onto a Kubernetes cluster on Digital Ocean involves several steps using Pulumi:

    1. Create a Kubernetes cluster: First, you need to create a Kubernetes cluster where your Helm chart will be deployed. With Pulumi, you can define the desired state of the cluster using code.
    2. Install Helm: Helm is a package manager for Kubernetes, which simplifies the deployment of applications. Pulumi has support for Helm, allowing you to declare the need for a Helm chart in code, which will then be automatically deployed to your cluster.
    3. Deploy the Helm chart: Once the cluster is up and running, and Helm is installed, you can then deploy your specific Helm chart (in this case, 'lighthouse-jx').

    Below is a program written in TypeScript that accomplishes these steps with Pulumi. Please make sure you have Pulumi installed and configured with your Digital Ocean token before running this code.

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // The region where the cluster will be created version: "latest", // Specify the version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // Size for each node in the node pool nodeCount: 2, // Number of nodes in the node pool }, }); // Step 2: Use the kubeconfig of the newly created cluster to interact with it using the Kubernetes provider const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the helm chart using the Kubernetes Helm Chart resource const lighthouseChart = new kubernetes.helm.v3.Chart("lighthouse-jx", { repo: "jenkins-x", // Specify the Helm chart's repository chart: "lighthouse-jx", // Specify the Helm chart's name version: "0.1.0", // Specify the version of the chart // values: { ... }, // Optionally, if required, you can provide configuration values for the chart }, { provider: k8sProvider }); // Export the cluster's name and kubeconfig export const clusterName = cluster.name; export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    This program does the following:

    • Imports the Pulumi DigitalOcean and Kubernetes packages.
    • Creates a DigitalOcean Kubernetes cluster with a specified region, version, and node pool configuration.
    • Sets up the Pulumi Kubernetes provider to interact with the newly created cluster using its kubeconfig.
    • Deploys the 'lighthouse-jx' Helm chart to the Kubernetes cluster using Pulumi's Helm support.

    After running this Pulumi program, you will have a new Kubernetes cluster on Digital Ocean with the Lighthouse Jenkins X Helm chart deployed.

    To execute this Pulumi program, you would run the following commands in your terminal:

    1. pulumi new typescript — to create a new Pulumi project if you don't already have one.
    2. Copy the provided TypeScript code into the index.ts file that Pulumi generates in your project directory.
    3. pulumi up — to preview and deploy your infrastructure.

    Pulumi will show you a preview of the actions it will take based on the code above. If everything looks good, you can then proceed to confirm the deployment, and Pulumi will create the resources for you. Remember, the outputs will include important information such as cluster name and kubeconfig, which you will use to interact with your Kubernetes cluster.
