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

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.

Step by Step Explanation

Step 1: Create a VPC

We will start by creating a new VPC that will house our ECS cluster and EC2 instances.

Step 2: Create Subnets

Next, we will create public and private subnets within the VPC.

Step 3: Create an Internet Gateway

We will create an internet gateway and attach it to the VPC to allow internet access to the public subnets.

Step 4: Create a Security Group

We will create a security group that allows inbound and outbound traffic to the EC2 instances.

Step 5: Create an ECS Cluster

We will create an ECS cluster that will manage our EC2 instances and run our containerized applications.

Step 6: Launch an EC2 Instance

Finally, we will launch an EC2 instance within the ECS cluster and deploy a sample application.

Key Points

• We are using Pulumi to manage our infrastructure as code.
• The key AWS services involved are EC2, ECS, and VPC.
• We are creating a VPC, subnets, an internet gateway, a security group, and an ECS cluster.
• We are launching an EC2 instance within the ECS cluster to run a sample application.

Conclusion

In this solution, we demonstrated how to use Pulumi to set up an AWS ECS cluster with EC2 instances. We created a VPC, subnets, an internet gateway, a security group, and an ECS cluster, and launched an EC2 instance running a sample application. This setup provides a scalable and manageable way to run containerized applications on AWS.

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;
