How to Create an EC2 Instance Connect VPC Endpoint?

Introduction

In this guide, we will create an EC2 Instance Connect VPC endpoint using Pulumi in TypeScript. EC2 Instance Connect provides a secure and easy way to connect to your instances without needing to share and manage SSH keys. By creating a VPC endpoint for EC2 Instance Connect, you can ensure that the traffic between your VPC and EC2 Instance Connect stays within the AWS network, improving security and reducing latency.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, set up a new Pulumi project. If you haven’t already, install the Pulumi CLI and configure your AWS credentials.

Step 2: Create a New Pulumi Stack

Create a new Pulumi stack and initialize it with TypeScript as the language.

Step 3: Define the VPC

Define a new VPC or use an existing one. Ensure that the VPC has the necessary subnets and route tables.

Step 4: Create the VPC Endpoint

Create the VPC endpoint for EC2 Instance Connect. Specify the VPC ID, subnet IDs, and security group IDs.

Step 5: Export the VPC Endpoint ID

Export the VPC endpoint ID as an output so that it can be easily referenced in other parts of your infrastructure.

Key Points

• EC2 Instance Connect allows secure and easy connection to instances without managing SSH keys.
• Creating a VPC endpoint ensures traffic stays within the AWS network, improving security and reducing latency.
• Ensure that the VPC has the necessary subnets and route tables before creating the VPC endpoint.
• Exporting the VPC endpoint ID allows for easy reference in other parts of your infrastructure.

Conclusion

By following this guide, you have successfully created an EC2 Instance Connect VPC endpoint using Pulumi in TypeScript. This setup enhances the security and performance of your connections to EC2 instances by keeping the traffic within the AWS network. Pulumi makes it easy to define and manage your cloud infrastructure as code, providing a powerful and flexible way to automate your deployments.

Full Code Example

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

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

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

// Create a security group
const securityGroup = new aws.ec2.SecurityGroup("my-security-group", {
    vpcId: vpc.id,
    description: "Allow SSH",
    ingress: [{
        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: "my-security-group",
    },
});

// Create an EC2 Instance Connect Endpoint
const instanceConnectEndpoint = new aws.ec2transitgateway.InstanceConnectEndpoint("my-instance-connect-endpoint", {
    subnetId: subnet.id,
    securityGroupIds: [securityGroup.id],
    preserveClientIp: false,
    tags: {
        Name: "my-instance-connect-endpoint",
    },
});

// Create a VPC Endpoint for EC2 Instance Connect
const vpcEndpoint = new aws.ec2.VpcEndpoint("my-vpc-endpoint", {
    vpcId: vpc.id,
    serviceName: "com.amazonaws.us-west-2.ec2-instance-connect",
    vpcEndpointType: "Interface",
    subnetIds: [subnet.id],
    securityGroupIds: [securityGroup.id],
    privateDnsEnabled: true,
    tags: {
        Name: "my-vpc-endpoint",
    },
});

// Export the VPC ID, Instance Connect Endpoint ID, and VPC Endpoint ID
export const vpcId = vpc.id;
export const instanceConnectEndpointId = instanceConnectEndpoint.id;
export const vpcEndpointId = vpcEndpoint.id;
