AWS Transfer Family SFTP/FTPS Integration With Pulumi

Introduction

In this solution, we will set up an AWS Transfer Family service to enable SFTP and FTPS access using Pulumi with TypeScript. AWS Transfer Family is a fully managed service that enables you to transfer files into and out of AWS storage services. It supports protocols such as SFTP, FTPS, and FTP. This solution will help you create and manage the necessary AWS resources using Pulumi and TypeScript.

Step-by-Step Explanation

Step 1: Set up Pulumi and TypeScript

1. Install Pulumi CLI.
2. Create a new Pulumi project using TypeScript.
3. Configure AWS credentials.

Step 2: Create an S3 Bucket

1. Define an S3 bucket resource in Pulumi.
2. Configure the bucket to store the transferred files.

Step 3: Create an IAM Role

1. Define an IAM role for the AWS Transfer Family service.
2. Attach the necessary policies to the role.

Step 4: Set up AWS Transfer Family Server

1. Define the AWS Transfer Family server resource in Pulumi.
2. Configure the server to use SFTP and FTPS protocols.
3. Associate the IAM role with the server.

Step 5: Create a User for AWS Transfer Family

1. Define a user for the AWS Transfer Family service.
2. Configure the user with the necessary permissions and settings.

Key Points

• AWS Transfer Family supports SFTP, FTPS, and FTP protocols.
• Pulumi allows you to define and manage cloud resources using code.
• This solution uses TypeScript to define the infrastructure as code.
• The S3 bucket is used to store the transferred files.
• An IAM role is required to grant the necessary permissions to the AWS Transfer Family service.

Conclusion

In this solution, we demonstrated how to set up an AWS Transfer Family service with SFTP and FTPS access using Pulumi and TypeScript. By following the step-by-step instructions, you can create and manage the necessary AWS resources to enable secure file transfers. Pulumi’s infrastructure as code approach allows for easy management and automation of cloud resources.

Full Code Example

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

// Create an S3 bucket to store transferred files
const bucket = new aws.s3.Bucket("transferBucket", {
    bucket: "my-transfer-bucket",
});

// Create an IAM role for the Transfer Family service
const transferRole = new aws.iam.Role("transferRole", {
    assumeRolePolicy: {
        Version: "2012-10-17",
        Statement: [
            {
                Action: "sts:AssumeRole",
                Principal: {
                    Service: "transfer.amazonaws.com",
                },
                Effect: "Allow",
                Sid: ""
            }
        ]
    }
});

// Attach the necessary policies to the IAM role
const transferPolicy = new aws.iam.RolePolicyAttachment("transferPolicy", {
    role: transferRole.name,
    policyArn: "arn:aws:iam::aws:policy/AmazonS3FullAccess"
});

// Create the Transfer Family server
const transferServer = new aws.transfer.Server("transferServer", {
    endpointType: "PUBLIC",
    identityProviderType: "SERVICE_MANAGED",
    protocols: ["SFTP", "FTPS"],
    loggingRole: transferRole.arn,
});

// Create a user for the Transfer Family service
const transferUser = new aws.transfer.User("transferUser", {
    serverId: transferServer.id,
    userName: "transfer-user",
    role: transferRole.arn,
    homeDirectory: `/${bucket.bucket}`,
});

export const bucketName = bucket.bucket;
export const serverId = transferServer.id;
export const userName = transferUser.userName;
