Deploy the Jupyter Helm Chart on Rancher

Introduction

This guide provides a step-by-step approach to deploying the Jupyter Helm chart on a Rancher-managed Kubernetes cluster using Pulumi. We will be utilizing AWS as the cloud provider and TypeScript for scripting, aligning with the organization’s system requirements.

Step-by-Step Explanation

Step 1: Set Up Your Pulumi Project

To begin, ensure you have the Pulumi CLI installed. If it is not already installed, download it from Pulumi’s website. Once installed:

1. Create a new Pulumi project using the following command:

   pulumi new typescript
   

2. Follow the prompts to set up your new project. This will initialize your project environment.

Step 2: Configure AWS and Kubernetes Providers

Next, you need to configure the necessary providers:

1. Install the required Pulumi packages:

   npm install @pulumi/pulumi @pulumi/aws @pulumi/kubernetes
   

2. Set up your AWS credentials. This can be done by setting environment variables or using the AWS CLI to configure your profile.
3. Configure the Kubernetes provider to connect to your Rancher-managed cluster. You will need access to the kubeconfig file associated with your cluster.

Step 3: Deploy the Jupyter Helm Chart

With the providers configured, you can now deploy the Jupyter Helm chart:

1. Add the Helm chart repository and deploy the Jupyter chart using the following TypeScript code:

   import * as pulumi from "@pulumi/pulumi";
   import * as aws from "@pulumi/aws";
   import * as k8s from "@pulumi/kubernetes";
   
   // Create a Kubernetes provider
   const kubeconfig = new pulumi.Config("kubeconfig").require("config")
   const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig });
   
   // Deploy the Jupyter Helm chart
   const jupyterChart = new k8s.helm.v3.Chart("jupyter", {
       chart: "jupyterhub",
       version: "1.1.3",
       fetchOpts: {
           repo: "https://jupyterhub.github.io/helm-chart/"
       },
       values: {
           // Add any custom values here
       }
   }, { provider: k8sProvider });
   

Step 4: Deploy Your Pulumi Stack

Finally, deploy your Pulumi stack to apply the changes:

1. Run the following command to deploy your stack:

   pulumi up
   

2. Review the proposed changes and confirm to proceed with the deployment.

Key Points

• Ensure Pulumi CLI is installed before starting.
• Configure AWS and Kubernetes providers properly to connect to your Rancher-managed cluster.
• Use the provided TypeScript code to deploy the Jupyter Helm chart.
• Verify the deployment by running pulumi up and confirming the changes.

Summary

In this guide, we successfully set up a Pulumi project to deploy the Jupyter Helm chart on a Rancher-managed Kubernetes cluster using AWS and TypeScript. We covered the configuration of providers, deployment of the Helm chart, and the application of the Pulumi stack. For further reading, consult the Pulumi Kubernetes provider documentation and the Jupyter Helm chart documentation.

Full Code Example

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

// Create a Kubernetes provider
const kubeconfig = "<your-kubeconfig-content>";
const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig });

// Deploy the Jupyter Helm chart
const jupyterChart = new k8s.helm.v3.Chart("jupyter", {
    chart: "jupyterhub",
    version: "1.1.3",
    fetchOpts: {
        repo: "https://jupyterhub.github.io/helm-chart/"
    },
    values: {
        // Add any custom values here
    }
}, { provider: k8sProvider });

export const jupyterChartName = jupyterChart.getResource("v1/Service", "jupyter").metadata.name;
