How Do I Build an AWS ECS Cluster With Pulumi?

Building an AWS ECS Cluster with Pulumi

To build an AWS ECS cluster with Pulumi, we will use several key AWS services including VPC, Subnets, Security Groups, and ECS itself. The process involves creating a VPC, defining subnets, setting up security groups, and finally creating the ECS cluster and associated resources.

Step-by-Step Explanation

1. Setting up the VPC

First, we need to create a Virtual Private Cloud (VPC) to host our ECS cluster.

2. Creating Subnets

Within the VPC, we will create public and private subnets to host our ECS tasks.

3. Configuring Security Groups

Security groups will be configured to control the traffic to and from the ECS tasks.

4. Creating the ECS Cluster

Finally, we will create the ECS cluster and define the necessary task definitions and services.

Summary

In this guide, we have outlined the steps to create an AWS ECS cluster using Pulumi. By following these steps, you can set up a scalable and secure ECS cluster to run your containerized applications.

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

// Create Public Subnet
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 Private Subnet
const privateSubnet = new aws.ec2.Subnet("private-subnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.2.0/24",
    availabilityZone: "us-west-2a",
    tags: { Name: "private-subnet" },
});

// Create Security Group
const securityGroup = new aws.ec2.SecurityGroup("ecs-sg", {
    vpcId: vpc.id,
    description: "Allow all inbound traffic",
    ingress: [{
        protocol: "-1",
        fromPort: 0,
        toPort: 0,
        cidrBlocks: ["0.0.0.0/0"],
    }],
    egress: [{
        protocol: "-1",
        fromPort: 0,
        toPort: 0,
        cidrBlocks: ["0.0.0.0/0"],
    }],
    tags: { Name: "ecs-sg" },
});

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

export const vpcId = vpc.id;
export const publicSubnetId = publicSubnet.id;
export const privateSubnetId = privateSubnet.id;
export const securityGroupId = securityGroup.id;
export const ecsClusterId = ecsCluster.id;
