1. Deploy the mavenrepo helm chart on Google Kubernetes Engine (GKE)


    To deploy a Helm chart on Google Kubernetes Engine (GKE), you'll need to set up a few things:

    1. Provision a GKE cluster: We'll use the google-native.container/v1beta1.Cluster resource to create a new GKE cluster.

    2. Install Helm on the cluster: We'll use the kubernetes.helm.sh/v3.Release resource from Pulumi's Kubernetes provider, which represents a Helm chart release.

    Here's a step-by-step guide, followed by the TypeScript code that accomplishes these tasks:

    Step 1: Creating the GKE Cluster

    We'll start by defining a GKE cluster using the Cluster resource. You need to specify details like the name, the location, and node configurations depending on your requirements.

    Step 2: Installing the Helm Chart

    After the cluster is up and running, we can deploy the Helm chart onto it. For that, we need to create an instance of Release that points to the Maven Repository Helm chart.

    In the Helm release, you'll need to:

    • Specify the chart name—presumably mavenrepo if that's the name in the Helm repository.
    • Provide the repository URL where the chart can be found if it's not in the default Helm chart repository.
    • Set the namespace for the Helm release.
    • Configure values for the chart using the values parameter if necessary.

    Below is a comprehensive TypeScript program that you can use to deploy a Maven Repository Helm chart on GKE with Pulumi:

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1. Provision a GKE cluster const cluster = new gcp.container.Cluster("mavenrepo-cluster", { initialNodeCount: 2, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring", ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig to access the Cluster export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Step 2. Install the Maven Repository Helm chart const mavenrepoChart = new k8s.helm.v3.Release("mavenrepo", { chart: "mavenrepo", version: "1.0.0", // replace with the chart version you need repositoryOpts: { repo: "https://charts.example.com/", // replace with the Helm repository URL if needed }, values: { // specify your chart values here }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig }) }); // Export the Helm release name export const mavenrepoReleaseName = mavenrepoChart.name;

    This program accomplishes the following:

    • Defines a GKE cluster named mavenrepo-cluster with two nodes and uses the latest available version for both the master and nodes.
    • Exports the cluster's name and a kubeconfig file which allows you to interact with the cluster using kubectl or any Kubernetes client.
    • Creates a Helm release from the mavenrepo chart. It assumes that the chart is hosted at https://charts.example.com/ which you should replace with the actual URL of your chart repository.
    • The values object within the Helm release should be configured according to the specific needs of the Maven Repository chart you are using. This may include things such as persistence configuration, resource requests, and limits or any other configurable parameters of the Helm chart.

    Make sure to replace placeholders like the chart version, repository URL, and values with actual information corresponding to the Maven Repository Helm chart you want to deploy.

    To run the program:

    1. Ensure you have the Pulumi CLI installed and configured with the correct access to your GCP account.
    2. Save the code to a file with a .ts extension (e.g., deployMavenRepo.ts).
    3. Run pulumi up within the directory containing your .ts file to create the resources.

    Important Notes:

    • The Helm chart version (1.0.0 in the code) and repository URL (https://charts.example.com/ in the code) are placeholders and should be replaced with the actual values corresponding to the Maven Repository Helm chart you intend to deploy.
    • The kubeconfig is generated using Pulumi's built-in all and apply functions, which allow generating dynamic data after other resources have been created. This configuration enables you to use kubectl against the provisioned GKE cluster.

    Please replace the chart-related values with the actual Maven Repository chart details you wish to deploy.
