How Do I Create an AWS S3 Bucket?

Introduction

In this guide, we’ll explore how to create an AWS S3 bucket using Pulumi and TypeScript. Amazon S3 is a robust, scalable object storage service that ensures high durability and availability. This guide will help you understand how to define the resources needed to set up an S3 bucket and configure its properties, such as versioning and access control policies.

Step-by-Step Explanation

Step 1: Set Up the S3 Bucket

Below is the TypeScript configuration to create an AWS S3 bucket:

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

const myBucket = new aws.s3.BucketV2("my_bucket", {
    bucket: "my-awesome-bucket",
    acl: "private",
    versionings: [{
        enabled: true,
    }],
    tags: {
        Name: "MyBucket",
        Environment: "Dev",
    },
});

• Define the Bucket: Create a new S3 bucket named “my-awesome-bucket” with private access.
• Enable Versioning: Ensure that versioning is enabled to keep track of object versions.
• Tagging: Add tags for easy identification and management.

Step 2: Configure Public Access Block

const myBucketPublicAccess = new aws.s3.BucketPublicAccessBlock("my_bucket_public_access", {
    bucket: myBucket.id,
    blockPublicAcls: true,
    blockPublicPolicy: true,
    ignorePublicAcls: true,
    restrictPublicBuckets: true,
});

• Block Public Access: Set up a public access block to prevent public access to the bucket’s contents.

Step 3: Add a Bucket Policy

const myBucketPolicy = new aws.s3.BucketPolicy("my_bucket_policy", {
    bucket: myBucket.id,
    policy: pulumi.jsonStringify({
        Version: "2012-10-17",
        Statement: [{
            Action: "s3:GetObject",
            Effect: "Allow",
            Resource: pulumi.interpolate`${myBucket.arn}/*`,
            Principal: "*",
        }],
    }),
});

• Policy Configuration: Add a bucket policy allowing public read-only access to the bucket’s contents, while being cautious of security implications.

Step 4: Export Bucket Details

export const bucketId = myBucket.id;
export const bucketArn = myBucket.arn;

• Export Identifiers: Export the bucket ID and ARN for future reference and integration with other resources.

Key Points

• Security: Ensure that public access is blocked unless explicitly required.
• Versioning: Enable versioning to maintain historical versions of objects.
• Tagging: Use tags for effective resource management and tracking.
• Policy Management: Carefully configure bucket policies to balance accessibility and security.

Conclusion

By following this guide, you have successfully created a secure, versioned AWS S3 bucket with a well-defined access policy using Pulumi and TypeScript. Remember to adjust the bucket names, configurations, and policies to fit your specific requirements. This setup not only provides scalable storage but also ensures your data remains secure and organized.
