Deploy the verhuis-service helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you will need the Pulumi Kubernetes provider, which enables you to utilize Kubernetes resources, including Helm charts, within your Pulumi program.

Below is a TypeScript program that demonstrates how to deploy the verhuis-service Helm chart to an OKE cluster. This program assumes that you have already set up the Pulumi Kubernetes provider with the necessary configuration to interact with your OKE cluster.

I'll provide an explanation of the main parts of the Pulumi program:

Import the @pulumi/kubernetes package: This package includes the classes and functions you'll use to interact with Kubernetes resources.
Create an instance of kubernetes.helm.v3.Chart: This represents a Helm chart in Kubernetes. You'll pass in the name of the chart (verhuis-service), and additional configuration such as the repository URL if it is not a locally available chart.
Provide configuration options: These options can include values, which are specific configuration parameters for the Helm chart, and other Helm-related settings such as the namespace where the chart should be deployed.

Here's the Pulumi TypeScript code that shows how to deploy this Helm chart:

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

// The name of the Helm chart you want to deploy
const chartName = "verhuis-service";

// Optional: Specify the namespace where the Helm chart will be deployed.
// If not specified, it will be deployed in the 'default' namespace.
const namespace = "default";

// Instantiate the Helm chart using the Pulumi Kubernetes provider.
const verhuisChart = new kubernetes.helm.v3.Chart(chartName, {
    chart: chartName,
    // Replace with the URL where your Helm chart is located if not in the default repo
    // repo: "https://charts.example.com/",
    namespace: namespace,
    // Uncomment and specify the path if your Helm chart is located locally
    // path: "./path-to-helm-chart",
    // Specify custom values to override the Helm chart's default values.
    // values: { key: value }, // Replace with actual values if needed
}, { provider: new kubernetes.Provider("oke-provider", { kubeconfig: "<your-kubeconfig-here>" }) });

// Export the chart name and namespace in case you want to reference them later.
export const chartNameExport = chartName;
export const namespaceExport = namespace;

Make sure you replace the placeholder <your-kubeconfig-here> with your actual Kubeconfig file content, which is used by Pulumi to authenticate with your Kubernetes cluster.

After you have this Pulumi program, you can run the following commands to deploy the Helm chart:

pulumi up

This command will preview the changes and prompt you to proceed with the deployment. Confirm the deployment to apply the changes and deploy the Helm chart to your OKE cluster.

Remember, always review the Helm chart's values and configuration options to make sure they are set according to your requirements and environment. Adjust the values configuration in the code as necessary.
