Deploy the showoff helm chart on Rancher
TypeScriptDeploying a Helm chart on a Rancher-managed Kubernetes cluster involves several steps. First, you need to ensure you have a Kubernetes cluster registered and managed by Rancher. Then you will use the Rancher 2 Pulumi provider to interact with Rancher's APIs and deploy the Helm chart. I will guide you through the process using TypeScript and Pulumi.
Prerequisites:
- An existing Kubernetes cluster managed by Rancher
- Pulumi CLI installed and set up with the appropriate credentials
- Node.js and npm installed to run the TypeScript program
Steps:
-
Set up your Pulumi project: Initialize a new Pulumi project if you haven't done so already and install the required dependencies.
-
Install the Rancher 2 Pulumi package: Use npm to install the
@pulumi/rancher2
package, which allows you to interact with Rancher. -
Write the Pulumi code: We will write TypeScript code to deploy the "showoff" Helm chart to your Rancher-managed cluster. For this, you need to have the
Cluster
object from Rancher where you intend to deploy the Helm chart and access to the Helm repository where "showoff" is hosted. -
Deploy the Helm chart: Execute the Pulumi program to deploy the Helm chart.
Now, let's dive into the code. This program will illustrate how to deploy a Helm chart named "showoff" on a Rancher-managed Kubernetes cluster using Pulumi.
import * as rancher2 from "@pulumi/rancher2"; import * as pulumi from "@pulumi/pulumi"; // Assuming you already have a Rancher-managed Kubernetes cluster and have setup the Pulumi and Rancher credentials. // Provide the catalog including the Helm repository hosting 'showoff' and the cluster configuration const catalog = new rancher2.CatalogV2("showoff-repo", { // Replace with your cluster ID clusterId: "your-cluster-id", // URL of the Helm chart repository containing 'showoff' chart url: "https://charts.example.com/", // Optionally, specify the branch if the repository is a git repository gitBranch: "main", }); // Deploy 'showoff' Helm chart const install = new rancher2.AppV2("showoff-chart", { // Name of the cluster where to deploy the chart clusterId: "your-cluster-id", // Name of the namespace within the cluster where to deploy the chart namespace: "your-namespace", // Reference the catalog entry created above repoName: catalog.name, // Name of the chart to install chartName: "showoff", // Chart version, can specify a fixed version chartVersion: "1.0.0", // Optionally, provide values for the Helm chart values: ` image: repository: "example/showoff" tag: "latest" `, }); // Export the App name of the deployed Helm chart export const chartName = install.name;
After crafting the above program:
- Run
pulumi up
to launch the deployment. Pulumi will interact with Rancher to roll out your Helm chart on the specified Rancher-managed Kubernetes cluster. - Check the output of
pulumi up
, which should indicate that the "showoff" Helm chart is being deployed to the cluster. - After the deployment, you can manage your application using Rancher's UI or CLI.
Keep in mind that you will need to replace
"your-cluster-id"
,charts.example.com
, and"your-namespace"
with your actual Rancher cluster ID, Helm repository URL, and Kubernetes namespace where you want to deploy your application. Adjust"1.0.0"
to match the version of the "showoff" Helm chart you want to deploy.For more detailed information about the Rancher 2 Pulumi provider, you can visit the rancher2.AppV2 documentation.
By following these instructions and using the provided code, you will be able to deploy the "showoff" Helm chart on your Rancher-managed Kubernetes cluster.
