Deploy the Graylog Helm Chart on AWS EKS

Introduction

In this guide, we will deploy the Graylog Helm chart on an AWS EKS cluster using Pulumi. Graylog is a powerful log management tool that can be easily deployed using Helm charts. AWS EKS (Elastic Kubernetes Service) is a managed Kubernetes service that makes it easy to run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane.

Step-by-Step Explanation

Step 1: Set up AWS EKS Cluster

1. Create a VPC: First, we need to create a Virtual Private Cloud (VPC) where our EKS cluster will reside.
2. Create EKS Cluster: Next, we will create the EKS cluster within the VPC.
3. Create Node Group: We will then create a node group for the EKS cluster.

Step 2: Deploy Graylog Helm Chart

1. Add Helm Repository: Add the Helm repository that contains the Graylog chart.
2. Deploy Helm Chart: Use the Helm provider in Pulumi to deploy the Graylog chart to the EKS cluster.

Summary

By following this guide, you will have a Graylog instance running on an AWS EKS cluster. This setup leverages AWS’s managed Kubernetes service and Helm’s package management capabilities to simplify the deployment process.

Full Code Example

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 a VPC for our EKS cluster
const vpc = new aws.ec2.Vpc("eks-vpc", {
    cidrBlock: "10.0.0.0/16",
    enableDnsHostnames: true,
    enableDnsSupport: true,
    tags: {
        Name: "eks-vpc",
    },
});

// Create subnets for the VPC
const subnet1 = new aws.ec2.Subnet("subnet1", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
    mapPublicIpOnLaunch: true,
    tags: { Name: "subnet1" },
});

const subnet2 = new aws.ec2.Subnet("subnet2", {
    vpcId: vpc.id,
    cidrBlock: "10.0.2.0/24",
    availabilityZone: "us-west-2b",
    mapPublicIpOnLaunch: true,
    tags: { Name: "subnet2" },
});

// Create an EKS cluster
const cluster = new eks.Cluster("eks-cluster", {
    vpcId: vpc.id,
    subnetIds: [subnet1.id, subnet2.id],
    instanceType: "t3.medium",
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
    nodeAssociatePublicIpAddress: true,
});

// Deploy the Graylog Helm chart
const graylog = new k8s.helm.v3.Chart("graylog", {
    chart: "graylog",
    version: "1.0.0",
    fetchOpts: {
        repo: "https://helm.graylog.com",
    },
    values: {},
}, { provider: cluster.provider });

export const kubeconfig = cluster.kubeconfig;
