How to Upload Files to an S3 Bucket with AWS CLI

Introduction

In this lesson, we will learn how to upload files to an S3 bucket with AWS CLI. Amazon Simple Storage Service (S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. It is used to store and retrieve any amount of data from anywhere on the web.

Using the AWS Command Line Interface (CLI), you can easily upload files to an S3 bucket. The AWS CLI is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

In this lesson, we will cover the following topics:

Prerequisites

Before you can upload files to an S3 bucket with AWS CLI, you need to have an AWS account and an S3 bucket. If you don’t have an AWS account, you can create one here.

Once you have an AWS account, you can create an S3 bucket. To do this, log in to the AWS Management Console and navigate to the S3 service. Click the “Create Bucket” button and follow the instructions to create your bucket.

Once you have created your S3 bucket, you need to install the AWS CLI. The AWS CLI is available for Windows, Mac, and Linux. You can download the AWS CLI from here.

Uploading Files to an S3 Bucket

Once you have installed the AWS CLI, you can use it to upload files to an S3 bucket. To do this, you need to use the aws s3 cp command. This command allows you to copy files from your local machine to an S3 bucket.

For example, if you want to upload a file named myfile.txt to an S3 bucket named mybucket, you can use the following command:

aws s3 cp myfile.txt s3://mybucket

This command will upload the file myfile.txt to the mybucket S3 bucket.

You can also use the aws s3 sync command to upload multiple files to an S3 bucket. This command allows you to synchronize a local directory with an S3 bucket. For example, if you want to upload all the files in the myfiles directory to the mybucket S3 bucket, you can use the following command:

aws s3 sync myfiles s3://mybucket

This command will upload all the files in the myfiles directory to the mybucket S3 bucket.

Using AWS CDK with Typescript

You can also use the AWS Cloud Development Kit (CDK) to upload files to an S3 bucket. The AWS CDK is an open-source software development framework for defining cloud infrastructure in code. It allows you to define your infrastructure as code and deploy it using AWS services.

To use the AWS CDK to upload files to an S3 bucket, you need to create a CDK stack. A CDK stack is a collection of AWS resources that are defined in code. To create a CDK stack, you need to create a file named cdk.ts and add the following code:

import * as cdk from '@aws-cdk/core';
import * as s3 from '@aws-cdk/aws-s3';

export class MyStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const bucket = new s3.Bucket(this, 'MyBucket', {
      bucketName: 'mybucket',
    });

    bucket.upload('myfiles', 'myfiles');
  }
}

This code will create an S3 bucket named mybucket and upload all the files in the myfiles directory to the bucket.

Using Typescript

You can also use Typescript to upload files to an S3 bucket. To do this, you need to install the AWS SDK for JavaScript. The AWS SDK for JavaScript is a collection of software libraries that allow you to interact with AWS services from your JavaScript code.

Once you have installed the AWS SDK for JavaScript, you can use it to upload files to an S3 bucket. To do this, you need to create a file named upload.ts and add the following code:

import * as AWS from 'aws-sdk';

const s3 = new AWS.S3();

const params = {
  Bucket: 'mybucket',
  Key: 'myfile.txt',
  Body: 'Hello World!'
};

s3.upload(params, (err, data) => {
  if (err) {
    console.log(err);
  } else {
    console.log(data);
  }
});

This code will upload the file myfile.txt to the mybucket S3 bucket.

Conclusion

In this lesson, we learned how to upload files to an S3 bucket with AWS CLI. We covered the prerequisites, how to upload files to an S3 bucket, how to use AWS CDK with Typescript, and how to use Typescript. We also discussed the key learnings of the lesson.

By following the steps outlined in this lesson, you should now be able to upload files to an S3 bucket with AWS CLI.
