Deploy the vertx helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy a Vert.x Helm chart on Oracle Kubernetes Engine (OKE), you need to set up several resources:

An OCI Kubernetes cluster: First, you need an Oracle Kubernetes Engine (OKE) cluster. To manage Kubernetes resources in Pulumi, we will use the kubernetes provider.
Helm Chart for Vert.x: Once the cluster is up and running, you can deploy the Vert.x application using a Helm chart.

Helm charts help you define, install, and upgrade complex Kubernetes applications. The kubernetes.helm.v3.Chart resource in Pulumi is used to deploy applications using a Helm chart.

Below is the Pulumi TypeScript program that demonstrates how you would deploy the Vert.x Helm chart on OKE. This assumes that you already have access to an existing OKE cluster.

import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

// Create a Kubernetes Provider that targets our existing OKE cluster.
const provider = new k8s.Provider("oke-k8s", {
    kubeconfig: "<Your OKE Cluster kubeconfig>",
});

// Deploy the Vert.x Helm chart using the 'kubernetes.helm.v3.Chart' resource.
// Replace `<Chart and repository details>` with specifics of the Vert.x Helm chart that you're trying to deploy.
const vertxChart = new k8s.helm.v3.Chart("vertx-chart", {
    chart: "vertx",
    // You will need to replace `repo` and `version` with the actual repository and version details.
    // Use `fetchOpts` if the Helm chart is in a private repository or if you need any specific fetch options.
    fetchOpts: {
        repo: "https://<helm-chart-repository>",
    },
    version: "x.y.z", // Replace with the actual chart version
    namespace: "default", // You can specify a different namespace if required
}, { provider: provider });

// To validate if the deployment was successful, we may wish to export the Helm release's status.
export const vertxStatus = vertxChart.status;

In this example, replace "<Your OKE Cluster kubeconfig>" with the actual kubeconfig for your OKE cluster.

Make sure to replace the placeholders for the Helm chart repo (https://<helm-chart-repository>) and version (x.y.z) with the actual information for the Vert.x Helm chart you wish to deploy.

Finally, this code exports the status of the Helm release after deployment, which you can use to monitor the health and status of your Vert.x application.

To run this Pulumi program, save it to a file (for example, index.ts), and then simply run pulumi up in the command line within the same directory as your file. Ensure that you have Pulumi installed and configured for use with your OCI account.

Keep in mind that provisioning cloud resources with Pulumi might incur costs, depending on the services used and their pricing models. Always make sure to review Oracle's pricing models and ensure that your Pulumi project is configured appropriately.
