Deploy the url-shortener-redis helm chart on Rancher
TypeScriptTo deploy the
url-shortener-redis
Helm chart on a Rancher-managed Kubernetes cluster, you'll first need to have access to a Rancher environment and the ability to interact with it using Pulumi.Here's a breakdown of the tasks we're going to accomplish:
- Set up a Rancher cluster (if not already set up).
- Install the
url-shortener-redis
Helm chart onto the Rancher cluster.
In this guide, I'll assume that you have a Rancher cluster running and available to deploy to. We’ll be using Pulumi with the
rancher2
provider in TypeScript. Therancher2
provider allows us to interact with Rancher and manage its resources.First, let's begin by installing the necessary Pulumi packages:
# Install Pulumi CLI and the necessary plugins $ npm install @pulumi/pulumi @pulumi/rancher2
Next, we will create the Pulumi program in TypeScript.
Before starting, make sure you have:
- Pulumi CLI installed and configured Pulumi Installation Guide.
- Access to a Rancher environment with the appropriate permissions to deploy applications.
Here is a Pulumi TypeScript program that demonstrates how to deploy the
url-shortener-redis
Helm chart on a Rancher-managed Kubernetes cluster:import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import { CatalogV2, AppV2 } from "@pulumi/rancher2"; // Step 1: Set up the Rancher2 provider configuration // This assumes you have already set up the RANCHER_ACCESS_KEY, RANCHER_SECRET_KEY, and RANCHER_URL environment variables. const provider = new rancher2.Provider("rancher", { api_url: process.env.RANCHER_URL, accessKey: process.env.RANCHER_ACCESS_KEY, secretKey: process.env.RANCHER_SECRET_KEY, }); // Step 2: Declare the catalog containing the chart as a Pulumi resource const catalog = new CatalogV2("url-shortener-redis-catalog", { clusterId: "<cluster-id>", // Replace with your Rancher Cluster ID url: "https://charts.bitnami.com/bitnami", // The repository where the chart is located // other optional properties }, { provider }); // Step 3: Deploy the url-shortener-redis Helm chart using the HelmChart resource const app = new AppV2("url-shortener-redis-app", { clusterId: "<cluster-id>", // Replace with your Rancher Cluster ID namespace: "default", // Deploy to the default namespace, or specify a different one repoName: catalog.metadata.name, chartName: "redis", // Assuming that 'url-shortener-redis' refers to the 'redis' chart targetNamespace: "url-shortener", // You can specify additional chart values here values: ` redis: password: "your-redis-password" // Replace with the Redis password if needed `, // other optional properties }, { provider }); // Step 4: Export the deployed application's name and status export const appName = app.metadata.apply(metadata => metadata.name); export const appStatus = app.status.apply(status => status);
The
clusterId
is the identifier of the Kubernetes cluster managed by Rancher where you want to deploy the Helm chart. You would replace<cluster-id>
with the actual ID of your cluster, which you can obtain from the Rancher UI or API.Assuming 'url-shortener-redis' is a customized Redis chart, you would need to have that available in your chart repository, or use an existing Redis chart, configuring it as needed.
We also specify Redis-specific configurations under
values
such as the password for Redis. TheAppV2
is a Rancher resource that represents an application installed via Helm. TheCatalogV2
resource represents a collection of Helm chart repositories managed by Rancher.Once the program is written, you would run it using the
pulumi up
command in your terminal, which will prompt you to review and apply the changes.This code will result in the deployment of the
url-shortener-redis
Helm chart on your specified Rancher Kubernetes cluster. If you have any application-specific configurations, you can set them invalues
, following the structure of the Helm chart'svalues.yaml
definitions.It's important to replace placeholder values with actual information from your environment, such as the
clusterId
and Redis password. Please refer to the official Pulumi Rancher2 Provider documentation for more details on the available resources and their configurations.
