How Do I Deploy the Zotero Helm Chart on AWS EKS?

Introduction

Deploying applications on AWS EKS (Elastic Kubernetes Service) can be streamlined using Helm charts, which are packages of pre-configured Kubernetes resources. In this guide, we will walk through the process of deploying the Zotero application on an AWS EKS cluster using the Pulumi infrastructure as code tool. This approach simplifies the management and deployment of cloud resources and applications.

Step-by-Step Deployment Process

To deploy the Zotero Helm chart on an AWS EKS cluster using Pulumi, follow these steps:

1. Create an EKS Cluster: Set up an EKS cluster using Pulumi’s EKS module. This involves creating a VPC, subnet, and configuring the cluster’s instance types and capacities.
2. Deploy Zotero using Helm: Use the Helm provider to deploy the Zotero Helm chart onto the EKS cluster. This step involves specifying the chart details and repository.

Required Pulumi Packages

We will utilize the following Pulumi packages to achieve our deployment:

• @pulumi/aws for managing AWS resources.
• @pulumi/eks for creating and managing the EKS cluster.
• @pulumi/kubernetes for deploying the Helm chart.

Deployment Code

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

// Create an EKS cluster
const vpc = new aws.ec2.Vpc("vpc", {
    cidrBlock: "10.0.0.0/16",
});

const subnet = new aws.ec2.Subnet("subnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
});

const eksCluster = new eks.Cluster("eksCluster", {
    vpcId: vpc.id,
    subnetIds: [subnet.id],
    instanceType: "t3.medium",
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
});

// Export the cluster's kubeconfig
export const kubeconfig = eksCluster.kubeconfig;

// Create a Kubernetes provider instance
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: eksCluster.kubeconfig.apply(JSON.stringify),
});

// Deploy Zotero using Helm
const zoteroChart = new k8s.helm.v3.Chart("zotero", {
    chart: "zotero",
    version: "1.0.0", // Adjust the version as needed
    fetchOpts: {
        repo: "https://example.com/helm-charts", // Replace with the actual Helm chart repository
    },
}, { provider: k8sProvider });

export const zoteroService = zoteroChart.getResource("v1/Service", "zotero");

Explanation of the Code

1. VPC and Subnet: A VPC and a subnet are created to host the EKS cluster.
2. EKS Cluster: The EKS cluster is set up within the specified VPC and subnet. The instance type and desired capacity for the nodes are configured.
3. Kubernetes Provider: A Kubernetes provider instance is created using the EKS cluster’s kubeconfig to manage Kubernetes resources.
4. Zotero Helm Chart: The Zotero Helm chart is deployed using the Kubernetes provider, specifying the chart details and repository.

Steps to Run the Program

1. Ensure you have the Pulumi CLI installed and configured.
2. Ensure your AWS CLI is configured with the necessary permissions.
3. Create a new Pulumi project using pulumi new.
4. Replace the index.ts content with the code provided above.
5. Run pulumi up to deploy the infrastructure and the Zotero Helm chart.

Key Points

• Pulumi simplifies the deployment of AWS resources and applications.
• Helm charts provide a convenient way to package and deploy applications on Kubernetes.
• The deployment process involves setting up the infrastructure and deploying the application using Helm.

Conclusion

Deploying the Zotero application on AWS EKS using Helm and Pulumi provides a streamlined and efficient way to manage cloud infrastructure and applications. By following the steps outlined in this guide, you can set up an EKS cluster and deploy the Zotero application effectively. Remember to replace the Helm chart repository URL and version with the correct values for your deployment needs.
