Deploy the issue-service helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Rancher using Pulumi, you would typically begin by setting up your Pulumi environment and then writing the necessary code to create a Rancher Cluster where the Helm chart will be deployed. Next, you'd configure the appropriate Helm chart settings and deploy it using Pulumi's rancher2 provider.

Below is a TypeScript program that demonstrates how to deploy a Helm chart, named issue-service, to a Rancher-managed Kubernetes cluster. In this example, we'll assume that you already have a Rancher Kubernetes cluster running. If you don't, you'd use resources like rancher2.Cluster to create one.

First, we import the necessary Pulumi and Rancher2 packages. Then, we create a CatalogV2 resource that points to the location of the Helm chart repository. Next, we use a AppV2 resource, which represents a Helm release in a Rancher cluster. We specify the catalog, chart name, version, and other configurations required to deploy issue-service.

Ensure you have Pulumi installed and configured for use with your Kubernetes cluster and Rancher, and have access to the kubeconfig for your cluster.

Detailed Explanation and TypeScript Program

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

// Step 1: Define the catalog for the Helm chart repository
// Here you should replace <catalog-name>, <catalog-url>, and <catalog-branch>
// with your specific catalog's details where the issue-service chart is hosted.
const catalog = new rancher2.CatalogV2("issue-service-catalog", {
    name: "<catalog-name>",
    clusterId: "<your-cluster-id>", // Specify the Rancher cluster ID where to install the chart
    url: "<catalog-url>", // The URL for the Helm chart repository
    gitBranch: "<catalog-branch>", // The repository branch where the chart is located
    // For example, for Bitnami charts you could use https://charts.bitnami.com/bitnami and branch "master"
});

// Step 2: Deploy the issue-service helm chart from the defined catalog
// Here you should replace <namespace> with the namespace where you want to deploy
// You should also provide the correct version of the chart you want to deploy
const app = new rancher2.AppV2("issue-service-app", {
    clusterId: "<your-cluster-id>", // This should be the same cluster ID used for the catalog
    namespace: "<namespace>", // The namespace in the cluster where the Helm chart will be deployed
    repoName: catalog.name, // Use the catalog defined in Step 1
    chartName: "issue-service", // The name of the chart to deploy
    chartVersion: "<chart-version>", // The version of the chart to deploy
    values: { // Custom values for the Helm chart, as needed (YAML or inline values)
        key: "value",
        // ...
    },
    // In case you have additional configuration or customization, you would specify that here
});

// Export the name of the app as an output
export const appName = app.metadata.name;

In the above code, remember to replace placeholder values like <catalog-name>, <catalog-url>, <catalog-branch>, <your-cluster-id>, <namespace>, and <chart-version> with the actual information related to your deployment environment and the issue-service Helm chart you want to deploy.

After writing this code, you would execute it using the Pulumi CLI. The CLI tool will interpret this code and make the appropriate requests to the Rancher API to create the resources and deploy the Helm chart.

Make sure that the Rancher2 provider is properly configured to access your Rancher server. You also need to ensure that your Pulumi program has access to the kubeconfig file that provides credentials to interact with your Rancher-managed Kubernetes cluster.
