Using Aws Ec2 With Ecs

In this solution, we will use Pulumi to set up an AWS ECS cluster with EC2 instances. The key services involved are Amazon EC2, Amazon ECS, and AWS VPC. We will create a VPC, subnets, an internet gateway, a security group, and an ECS cluster with an EC2 instance running a sample application.

Introduction

This guide demonstrates how to set up an AWS ECS cluster with EC2 instances using Pulumi. The main AWS services involved are EC2, ECS, and VPC. We will establish a VPC, define subnets, configure an internet gateway, create a security group, and set up an ECS cluster that hosts an EC2 instance running a sample application.

Step-by-Step Explanation

Step 1: Create a VPC

Begin by creating a new VPC, which will serve as the network environment for your ECS cluster and EC2 instances.

Step 2: Create Subnets

Within the VPC, create both public and private subnets to organize and manage network traffic efficiently.

Step 3: Create an Internet Gateway

Set up an internet gateway and attach it to the VPC. This will enable internet access for resources in the public subnets.

Step 4: Create a Security Group

Establish a security group to manage inbound and outbound traffic rules for the EC2 instances, ensuring secure access.

Step 5: Create an ECS Cluster

Create an ECS cluster, which will orchestrate the management of EC2 instances and deployment of containerized applications.

Step 6: Launch an EC2 Instance

Deploy an EC2 instance within the ECS cluster and run a sample application to verify the setup.

Key Points

• Pulumi is used to manage infrastructure as code.
• The primary AWS services are EC2, ECS, and VPC.
• The setup includes creating a VPC, subnets, an internet gateway, a security group, and an ECS cluster.
• An EC2 instance is launched within the ECS cluster to run a sample application.

Conclusion

This solution effectively demonstrates setting up an AWS ECS cluster with EC2 instances using Pulumi. By creating a VPC, subnets, an internet gateway, a security group, and an ECS cluster, we successfully launched an EC2 instance to host a sample application. This configuration offers a robust and scalable method for deploying containerized applications on AWS.

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,
    tags: { Name: "my-vpc" },
});

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

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

// Create a Security Group
const securityGroup = new aws.ec2.SecurityGroup("security-group", {
    vpcId: vpc.id,
    description: "Allow all HTTP and SSH traffic",
    ingress: [
        { protocol: "tcp", fromPort: 80, toPort: 80, cidrBlocks: ["0.0.0.0/0"] },
        { protocol: "tcp", fromPort: 22, toPort: 22, cidrBlocks: ["0.0.0.0/0"] },
    ],
    egress: [
        { protocol: "-1", fromPort: 0, toPort: 0, cidrBlocks: ["0.0.0.0/0"] },
    ],
    tags: { Name: "security-group" },
});

// Create an ECS Cluster
const ecsCluster = new aws.ecs.Cluster("ecs-cluster", {
    name: "my-ecs-cluster",
});

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

export const vpcId = vpc.id;
export const subnetIds = [publicSubnet.id];
export const internetGatewayId = internetGateway.id;
export const securityGroupId = securityGroup.id;
export const ecsClusterArn = ecsCluster.arn;
export const ec2InstanceId = ec2Instance.id;
