Using Aws Ec2 With Opensearch

Introduction

In this solution, we will use Pulumi to provision an AWS EC2 instance and an Amazon OpenSearch Service domain using TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. AWS EC2 (Elastic Compute Cloud) provides scalable computing capacity, while Amazon OpenSearch Service (successor to Amazon Elasticsearch Service) is a fully managed service that makes it easy to deploy, operate, and scale OpenSearch clusters in the AWS Cloud.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

1. Initialize a new Pulumi project.
2. Install the necessary Pulumi packages for AWS.

Step 2: Configure AWS Provider

1. Set up the AWS provider with the required configuration.

Step 3: Create a VPC

1. Define a new VPC to host the EC2 instance and OpenSearch domain.
2. Create subnets, route tables, and internet gateways as needed.

Step 4: Launch an EC2 Instance

1. Define the EC2 instance with the desired configuration (e.g., instance type, AMI, key pair).
2. Configure security groups to allow necessary traffic.

Step 5: Create an OpenSearch Domain

1. Define the OpenSearch domain with the desired configuration (e.g., instance type, number of nodes, storage).
2. Configure access policies and network settings.

Step 6: Output Relevant Information

1. Output the EC2 instance public IP address.
2. Output the OpenSearch domain endpoint.

Key Points

• Pulumi allows you to define cloud infrastructure using familiar programming languages.
• AWS EC2 provides scalable computing capacity in the cloud.
• Amazon OpenSearch Service is a fully managed service for deploying and managing OpenSearch clusters.
• Proper configuration of VPC, security groups, and access policies is crucial for secure and efficient operation.

Conclusion

By following this guide, you have successfully provisioned an AWS EC2 instance and an Amazon OpenSearch Service domain using Pulumi and TypeScript. This solution demonstrates the power and flexibility of Pulumi in managing cloud infrastructure as code, enabling you to automate the provisioning and management of complex cloud resources efficiently.

Full Code Example

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

// Create a VPC
const vpc = new aws.ec2.Vpc("my-vpc", {
    cidrBlock: "10.0.0.0/16",
    enableDnsSupport: true,
    enableDnsHostnames: true,
});

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

// Create an Internet Gateway
const internetGateway = new aws.ec2.InternetGateway("my-igw", {
    vpcId: vpc.id,
});

// Create a route table
const routeTable = new aws.ec2.RouteTable("my-route-table", {
    vpcId: vpc.id,
    routes: [{
        cidrBlock: "0.0.0.0/0",
        gatewayId: internetGateway.id,
    }],
});

// Associate the route table with the subnet
new aws.ec2.RouteTableAssociation("my-route-table-association", {
    subnetId: subnet.id,
    routeTableId: routeTable.id,
});

// Create a security group
const securityGroup = new aws.ec2.SecurityGroup("my-security-group", {
    vpcId: vpc.id,
    ingress: [{
        protocol: "tcp",
        fromPort: 22,

        fromPort: 0,
        toPort: 0,
        cidrBlocks: ["0.0.0.0/0"],
    }],
});

// Launch an EC2 instance
const ec2Instance = new aws.ec2.Instance("my-instance", {
    instanceType: "t2.micro",
    ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2 AMI
    subnetId: subnet.id,
    vpcSecurityGroupIds: [securityGroup.id],
    associatePublicIpAddress: true,
});

// Create an OpenSearch domain
const openSearchDomain = new aws.opensearch.Domain("my-opensearch-domain", {

    engineVersion: "OpenSearch_1.0",
    clusterConfig: {
        instanceType: "t3.small.search",

    },
    ebsOptions: {
        ebsEnabled: true,
        volumeSize: 10,
    },
    accessPolicies: JSON.stringify({
        Version: "2012-10-17",
        Statement: [{
            Effect: "Allow",
            Principal: {
                AWS: "*",

    vpcOptions: {
        subnetIds: [subnet.id],
        securityGroupIds: [securityGroup.id],
    },

// Export the EC2 instance public IP and OpenSearch domain endpoint
export const ec2InstancePublicIp = ec2Instance.publicIp;
export const openSearchDomainEndpoint = openSearchDomain.endpoint;
