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

    TypeScript

    To deploy the jx-app-sonarqube Helm chart on a DigitalOcean Kubernetes Service, you'll need to complete several steps, and we'll walk through these together in this guide. Pulumi provides a structured way to manage cloud resources using infrastructure as code, and with TypeScript, this process becomes flexible and familiar for JavaScript/TypeScript developers.

    Here's an outline of what we'll be doing:

    1. Provision a DigitalOcean Kubernetes Cluster: We'll create a Kubernetes cluster in DigitalOcean using the digitalocean.KubernetesCluster resource from the DigitalOcean Pulumi provider.

    2. Install the Helm Chart: After our Kubernetes cluster is up and running, we'll deploy the jx-app-sonarqube Helm chart to the cluster using the kubernetes.helm.v3.Chart resource from the Kubernetes Pulumi provider.

    Prerequisites

    • Pulumi: Make sure you have the Pulumi CLI installed.
    • DigitalOcean Token: Ensure that you have a DigitalOcean personal access token that you'll use to authenticate with DigitalOcean.
    • Kubernetes Configuration: Pulumi needs to be able to connect to the Kubernetes cluster to manage resources. By default, it uses the kubeconfig file on your local machine.

    Pulumi Program

    Below is the TypeScript program that accomplishes the deployment:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Provision a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // Choose the region that best fits your needs version: "latest", // Use the latest version of Kubernetes nodePool: { size: "s-2vcpu-4gb", // Choose the size that fits your needs name: "default", nodeCount: 2, // Specify the number of nodes in the node pool }, }); // After the cluster is created, we can export the kubeconfig export const kubeConfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Deploy the jx-app-sonarqube Helm chart to the cluster // First, we use the kubeConfig we obtained from the cluster to configure our Kubernetes provider instance const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeConfig, }); // Next, we declare our Helm chart resource const sonarqubeChart = new kubernetes.helm.v3.Chart("sonarqube-chart", { chart: "sonarqube", version: "1.0.0", // Specify the version of the chart fetchOpts: { repo: "https://charts.oteemo.com", // The repo where the SonarQube chart can be found }, }, { provider: k8sProvider }); // Pass the provider to ensure it uses the correct kubeconfig // Output the endpoint to access SonarQube export const sonarqubeEndpoint = sonarqubeChart.getResourceProperty("v1/Service", "sonarqube-sonarqube", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Explanation

    • First, we import the necessary libraries from Pulumi for DigitalOcean and Kubernetes.
    • We provision a new Kubernetes cluster on DigitalOcean using digitalocean.KubernetesCluster.
      • region specifies the location for our cluster.
      • version is set to latest, so we use the most recent supported Kubernetes version.
      • nodePool defines the details of our cluster nodes such as size, name, and count.
    • We output kubeConfig, which contains the necessary information to connect to our Kubernetes cluster with kubectl or any Kubernetes client.
    • Using the kubeconfig, we configure the Kubernetes provider. This provider is needed by Pulumi to interact with our new Kubernetes cluster.
    • We deploy the jx-app-sonarqube Helm chart using kubernetes.helm.v3.Chart.
      • chart specifies the Helm chart we want to deploy, which is sonarqube.
      • version allows us to pin the chart to a specific version.
      • fetchOpts.repo is the URL of the Helm repo where the chart is stored.
    • Finally, we export an endpoint that can be used to access the SonarQube UI once it's deployed. This is done by getting the load balancer's IP address of the SonarQube service from the chart's resources.

    Next Steps

    After you have saved the above program to a file (e.g., index.ts), run it with the following Pulumi CLI commands:

    1. Initialize a Pulumi project and stack:
    pulumi new typescript --dir my-project cd my-project
    1. Copy and paste the TypeScript program into index.ts.

    2. Install the necessary dependencies:

    npm install @pulumi/digitalocean @pulumi/kubernetes @pulumi/pulumi
    1. Run pulumi up to preview and deploy the changes:
    pulumi up

    After confirming, Pulumi will carry out the necessary steps to provision your DigitalOcean Kubernetes cluster and deploy SonarQube with Helm.

    1. Access SonarQube:

    Once the deployment is successful, you can use the sonarqubeEndpoint output to access SonarQube in a web browser. It can take a few minutes for the load balancer to assign an IP address and for SonarQube to start up.
