Deploy the contour-operator helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Contour Operator Helm chart on a Kubernetes cluster using Pulumi, you will need to utilize the Chart resource from Pulumi's Kubernetes provider. This resource allows you to deploy Helm charts into your cluster in a declarative way using infrastructure as code.

Here's how you can approach the deployment:

Import necessary packages.
Create an instance of the Chart resource, specifying the contour-operator chart and its settings.
Optionally export any outputs you may need, such as service URLs or other data points.

Below is a detailed example of how to accomplish this in TypeScript.

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

// Step 1: Create a new Kubernetes Namespace (optional)
// This step is optional, if you prefer to deploy the Helm chart in a specific namespace.
const ns = new k8s.core.v1.Namespace("contour-operator-namespace", {
    metadata: {
        name: "contour-operator"
    }
});

// Step 2: Deploy the Contour Operator Helm chart
// Here we use the `Chart` resource that represents a Helm chart.
const contourOperatorChart = new k8s.helm.v3.Chart("contour-operator-chart", {
    // The `chart` parameter specifies the name of the chart from the Helm repository.
    chart: "contour-operator",

    // Optionally, you can specify the `version` of the chart.
    version: "1.0.0", // replace with the actual chart version you wish to deploy

    // `namespace` is the target Kubernetes namespace where the chart should be deployed. 
    // This should be the name of the namespace we created above.
    // If you didn't create a namespace, you can omit this or use an existing one.
    namespace: ns.metadata.name,

    // `fetchOpts` lets you customize the fetching of the Helm chart, such as adding a `repo` URL.
    fetchOpts: {
        // The repository URL where the chart is hosted. Replace <repo_url> with the actual URL.
        repo: "https://<repo_url>" // for example: "https://charts.bitnami.com/bitnami"
    },

    // Optionally, you can specify `values` to customize the deployment configuration.
    // This could be from a configuration file or an in-code object structure.
    values: {
        // These settings will depend on the specific configurations that `contour-operator` provides.
        // For example, to change the service type to LoadBalancer, you might use:
        // service: { type: "LoadBalancer" }
    }
}, { dependsOn: ns });

// Step 3: Export the deployment details
// For example, if you want to export the IP address of the LoadBalancer (if applicable):
export const ipAddress = contourOperatorChart.getResourceProperty("v1/Service", "contour-operator", "status")
    .apply(status => status.loadBalancer.ingress[0].ip);

Let's break down the code:

We start by importing the @pulumi/kubernetes package, which provides us with the classes and functions we need to interact with Kubernetes resources.
We optionally create a namespace to deploy our chart. This is a good practice to keep resources organized.
Next, we instantiate a new Chart resource named contour-operator-chart. We pass the chart name as contour-operator, and we may provide the Helm chart version explicitly.
We specify the repository URL via fetchOpts.repo where the Helm chart is hosted. This should be replaced with the actual URL for the contour-operator chart.
We also pass values which represent the configuration values for the Helm chart. These would be specific to contour-operator and can control various aspects of the deployment.
Lastly, we demonstrate how to export an output, such as the LoadBalancer IP address, if the contour-operator service uses a LoadBalancer. This step will vary depending on the actual resources created by the Helm chart.

Please replace placeholder values like 1.0.0, <repo_url>, and any values configuration with the actual values that you intend to use for deploying the contour-operator Helm chart.

After setting up the Pulumi program, you can run it using the Pulumi CLI commands pulumi up to deploy and pulumi destroy to tear down the resources.

Remember, when working with Pulumi, you must have Pulumi installed and configured to interact with your Kubernetes cluster. This typically involves running pulumi login to authenticate with the Pulumi service and setting up your kubeconfig so that Pulumi can interact with your Kubernetes cluster.
