Deploy the federated-gateway helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the federated-gateway Helm chart on Kubernetes using Pulumi, you need to follow these steps:

Set up your Kubernetes cluster where you want to deploy the Helm chart. This step assumes that you have a running Kubernetes cluster and the kubeconfig file is correctly set up to connect to your cluster.
Install the Pulumi CLI and set up the Pulumi project. If you haven't done that already, you will need to install Pulumi and create a new Pulumi TypeScript project.
Add the @pulumi/kubernetes npm package to your project. This package allows you to interact with Kubernetes resources using Pulumi.
Use the helm.v3.Chart class from the Pulumi Kubernetes provider to deploy the federated-gateway Helm chart.

Below is a TypeScript program that illustrates how you would use Pulumi to deploy a Helm chart to Kubernetes. Replace <your-chart-name> with the actual name of your chart, and <your-chart-version> with the version of the chart you want to use. If your Helm chart is located in a private repository, you'll also need to specify the repository URL and any other necessary parameters.

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

// Create an instance of the Helm chart `federated-gateway`. This assumes that the Helm chart
// is publicly available. If it's a private chart, you will need to provide authentication details.
const federatedGatewayChart = new k8s.helm.v3.Chart("federated-gateway", {
    chart: "federated-gateway",  // Replace with the correct chart name
    // If specifying a specific version, uncomment the following line and replace with the desired version:
    // version: "<your-chart-version>",
    // If the chart is in a custom repo, uncomment the two following lines and set the `repo` field:
    // fetchOpts: {
    //     repo: "http://<repository-url>",  // Replace with the Helm repository URL
    // },
    // You can also specify values for the Helm chart using the `values` field, for example:
    // values: {
    //     key1: "value1",
    //     key2: "value2",
    // },
});

// Export the chart's public IP (if relevant).
export const gatewayIp = federatedGatewayChart.getResourceProperty("v1/Service", "federated-gateway", "status")
    .apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

In the above code:

We import the Pulumi Kubernetes package.
We instantiate a Chart from the @pulumi/kubernetes/helm/v3 module, providing it with the name of our Helm release and various options. This includes the Helm chart name, optionally the version, and any other custom values you want to provide to the Helm chart.
We export a stack output for the public IP or hostname of the gateway service. This assumes that the Helm chart creates a service of type LoadBalancer. If the service is of a different type or if you need to access other resources, you would adjust this accordingly.

Remember to replace placeholder values with actual values suitable for your situation. If you require additional configurations, like setting up a namespace or specifying resource options, you can include those settings within your Pulumi program as well.

After you've written your Pulumi program in a file named index.ts, you would run pulumi up to deploy the Helm chart to your Kubernetes cluster.

The Pulumi CLI will show you a preview of the actions that will be performed and, upon confirmation, apply those actions to deploy the resources defined in the program. If the Helm chart includes services of type LoadBalancer, after the deployment finishes, you should be able to retrieve the external IP address or hostname from the Pulumi stack output and access your federated gateway using that address.
