Deploy the istio-ratelimit-operator helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the istio-ratelimit-operator Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would typically follow these high-level steps:

Set up the Rancher2 provider so that Pulumi can interact with your Rancher instance.
Obtain the necessary credentials and cluster information for the Kubernetes cluster managed by Rancher.
Use the Pulumi Kubernetes provider to deploy the Helm chart to the Kubernetes cluster.

Let's go through a program that would deploy the istio-ratelimit-operator Helm chart on a Rancher cluster. Please note that you will need appropriate credentials for both Rancher and the Kubernetes cluster, and this program assumes that the Rancher2 Pulumi provider and the Kubernetes Pulumi provider have been set up correctly in your environment.

Here's how you can write a Pulumi program in TypeScript to deploy the istio-ratelimit-operator Helm chart:

import * as pulumi from '@pulumi/pulumi';
import * as k8s from '@pulumi/kubernetes';
import * as rancher2 from '@pulumi/rancher2';

// Step 1: Set up Rancher2 provider configuration
// Ensure you have the appropriate Rancher API URL and access tokens set up in your environment
const rancherProvider = new rancher2.Provider('rancherProvider', {
    apiURL: 'https://<your-rancher-api-url>',
    accessKey: '<your-rancher-api-access-key>',
    secretKey: '<your-rancher-api-secret-key>',
    // See https://www.pulumi.com/registry/packages/rancher2/installation-configuration/ for more info
});

// Step 2: Obtain cluster information
// Replace `<cluster-id>` with the actual ID of your cluster
const cluster = rancher2.getCluster({
    id: '<cluster-id>',
}, { provider: rancherProvider });

// Step 3: Set up the Kubernetes provider with credentials from the targeted Rancher cluster
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: cluster.kubeConfig,
});

// Step 4: Deploy the istio-ratelimit-operator Helm chart using the Kubernetes provider
const istioRatelimitOperatorChart = new k8s.helm.v3.Chart('istio-ratelimit-operator', {
    chart: 'istio-ratelimit-operator',
    version: 'x.y.z', // specify the version of the chart you want to deploy
    fetchOpts: {
        repo: 'http://<helm-chart-repo>', // specify the Helm repository URL where the chart is located
    },
}, { provider: k8sProvider });

// Optionally, you can export the status of the deployed Helm release
export const istioRatelimitOperatorStatus = istioRatelimitOperatorChart.status;

In this program:

rancher2.Provider is used to configure the Rancher provider. You will have to replace <your-rancher-api-url>, <your-rancher-api-access-key>, and <your-rancher-api-secret-key> with the appropriate values from your Rancher setup.
rancher2.getCluster() obtains the necessary configuration about the Kubernetes cluster managed by Rancher, using its cluster ID (<cluster-id>).
k8s.Provider sets up the Kubernetes provider to allow Pulumi to deploy resources to the specified Kubernetes cluster. The kubeconfig is dynamically retrieved from the Rancher cluster configuration.
k8s.helm.v3.Chart represents the Helm chart that you want to deploy, in this case, istio-ratelimit-operator. You must specify the version of the chart you want to deploy and the Helm repository URL (<helm-chart-repo>) where the chart is hosted. If you don't have a specific version or repository, you can omit these and Pulumi will use default values.

Please ensure that you have the @pulumi/kubernetes and @pulumi/rancher2 NPM packages installed in your project, and replace placeholder values with your specific configuration details as commented in the code above. The istio-ratelimit-operator Helm chart should also be available in the specified Helm chart repository for this code to work correctly. If it's not, you'll need to make adjustments accordingly.
