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


    To deploy the rtorrent Helm chart on Google Kubernetes Engine (GKE), you will need to complete several steps:

    1. Provision a GKE cluster.
    2. Install and configure Helm in your local environment or wherever you run Pulumi.
    3. Use Pulumi's Helm support to deploy the rtorrent chart to your GKE cluster.

    Below you'll find a Pulumi program written in TypeScript that demonstrates how to accomplish these steps. This program uses Pulumi’s @pulumi/gcp package for creating the GKE cluster and Pulumi's @pulumi/kubernetes package to deploy the Helm chart.

    First, let's install the necessary Pulumi packages by running:

    npm install @pulumi/gcp @pulumi/kubernetes

    Once the packages are installed, you can create a new TypeScript Pulumi program.

    Make sure you have configured your Pulumi with GCP credentials, and your default project and zone settings are as desired.

    Here's the detailed Pulumi program:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Create a GKE cluster const cluster = new gcp.container.Cluster("rtorrent-cluster", { initialNodeCount: 2, minMasterVersion: "latest", nodeConfig: { machineType: "n1-standard-1", // Or any other desired machine type 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 and Kubeconfig export const clusterName = cluster.name; export const kubeconfig = cluster.endpoint.apply(endpoint => { return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${cluster.masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${cluster.name} contexts: - context: cluster: ${cluster.name} user: ${cluster.name} name: ${cluster.name} current-context: ${cluster.name} kind: Config users: - name: ${cluster.name} 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 `; }); // Create a provider for the created cluster const clusterProvider = new k8s.Provider("gke-k8s", { kubeconfig: kubeconfig, }); // Deploy rtorrent Helm chart on GKE cluster const rtorrentChart = new k8s.helm.v3.Chart("rtorrent", { chart: "rtorrent", version: "1.0.0", // Replace with the actual chart version fetchOpts: { repo: "http://your-helm-chart-repository/", // Replace with the actual Helm chart repository URL }, }, { provider: clusterProvider }); // Export the Helm chart status and ready message export const rtorrentStatus = rtorrentChart.status; export const rtorrentReadyMessage = rtorrentChart.status.apply(status => status === 'deployed' ? 'rtorrent Helm chart is deployed!' : 'rtorrent Helm chart deployment is pending...');

    In this program, we first create a GKE cluster with a basic configuration, specifying the number of nodes and the machine type. We then export the cluster name and a generated kubeconfig. This kubeconfig is required to interact with the cluster using the Kubernetes API, which Pulumi does behind the scenes.

    Next, we create a Kubernetes provider that uses the kubeconfig of the newly created GKE cluster. This provider will be used by Pulumi to deploy resources to the correct cluster.

    Lastly, we define a Helm chart resource using the k8s.helm.v3.Chart class from the @pulumi/kubernetes package. We specify the name of the chart (rtorrent), the chart version, and the repository where the Helm chart is located. The provider we pass to the chart ensures it gets deployed to our GKE cluster.

    The rtorrentStatus and rtorrentReadyMessage are exports that help us understand the status of our Helm chart deployment.

    Make sure to replace the placeholders such as "http://your-helm-chart-repository/" with actual URLs and versions corresponding to the rtorrent Helm chart. As of my last knowledge, there may not be an officially-published Helm chart for rTorrent, so you might need to create one or use a community-maintained chart.

    Run this program with Pulumi to provision the resources on Google Cloud. After the program completes execution, the rtorrent Helm chart should be deployed to your GKE cluster.
