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


    To deploy the Vert.x Helm chart on Google Kubernetes Engine (GKE) using Pulumi, we will go through a step-by-step process:

    1. Set up a GKE Cluster: We need to create a GKE cluster where our application will be deployed.
    2. Install the Helm Chart: Once we have a Kubernetes cluster, we can proceed to install the Helm chart for Vert.x.

    Firstly, we need to set up a GKE cluster using Pulumi's GCP provider. The google-native.container/v1.Cluster resource will allow us to create this cluster. We choose this resource because it is high-level and provides us with the necessary properties to configure a cluster in GKE.

    Once the cluster is available, we'll use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider to deploy the Vert.x Helm chart. The Helm chart resource gives us an interface to work with Helm charts similar to how we would with the Helm CLI but programmatically through Pulumi.

    Below is a TypeScript program using Pulumi that accomplishes the deployment of a Vert.x Helm chart on a GKE cluster:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; const name = "vertx-cluster"; // Creating a GKE cluster const cluster = new gcp.container.Cluster(name, { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "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 kubeconfig to access the cluster with kubectl 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: client-certificate-data: ${masterAuth.clientCertificate} client-key-data: ${masterAuth.clientKey} `; }); // Create a Kubernetes provider instance that uses our cluster from above. const clusterProvider = new k8s.Provider(name, { kubeconfig: kubeconfig, }); // Deploy the vertx Helm chart onto the GKE cluster const vertxChart = new k8s.helm.v3.Chart("vertx-chart", { chart: "vertx", version: "1.0.0", // Replace with the desired chart version fetchOpts: { repo: "http://your-helm-chart-repository/", // Specify the repository hosting the Vert.x Helm chart }, }, { provider: clusterProvider }); // Export the public IP to access the Vert.x service export const vertxPublicIp = vertxChart.getResourceProperty("v1/Service", "vertx-chart", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Here's how the Pulumi program works:

    • We define the cluster constant, where we use gcp.container.Cluster to set up a GKE cluster.
    • We export kubeconfig, which will be used to communicate with our GKE cluster.
    • We create a k8s.Provider which is required by the Helm chart resource to know which cluster we're working with.
    • We then define the vertxChart constant using k8s.helm.v3.Chart. This resource is responsible for deploying the requested Helm chart to our cluster.
    • Finally, we export vertxPublicIp which fetches the load balancer IP that is allocated to the deployed service, allowing us to access the Vert.x application from the internet.

    Please replace the placeholder values (e.g., http://your-helm-chart-repository/) with actual values that you wish to use in your deployment.

    To deploy this program:

    1. Save the code to a file with a .ts extension, for instance, index.ts.
    2. Run pulumi up in the same directory where the file is located. Pulumi CLI will execute the code and create the resources in your GCP account. Make sure you have the correct GCP configuration set up.

    Upon successful execution, Pulumi will provide you with the vertxPublicIp which you can use to access your Vert.x application on the internet.
