How to Launch AWS S3 bucket using Shell Scripting.

We all need a place to store data such deployment scripts, deployment packages also to host a website we require space. In earlier days there were servers where data use to take lot of time to be copied and those servers were not scalable and neither fault tolerant. In case there was issue such as server down or server gets corrupted , data was either lost or application use to remain down for long hours.

In order to solve space or data storage issue with unlimited capacity and scalable with tolerant behaviors Amazon AWS provides a service AWS S3 which solves all these problem.

In this tutorial we will demo how to launch a AWS S3 bucket in Amazon account using Bash or shell scripting .

What is Shell Scripting or Bash Scripting?

Shell Script is simply a text of file with various or lists of commands that are executed even on terminal or shell one by one. But in order to make thing little easier and run together as a group and in quick time we write them in single file and run it.

Main tasks which are performed by shell scripts are : file manipulation , printing text , program execution. We can include various environmental variables in script that can be used at multiple places , run programs and perform various activities are known as wrapper scripts.

A good shell script will have comments, preceded by a pound sign or hash mark, #, describing the steps. Also we can include conditions or pipe some commands to make more creative scripts.

When we execute a shell script, or function, a command interpreter goes through the ASCII text line-by-line, loop-by-loop, test-by-test, and executes each statement as each line is reached from the top to the bottom.

What is Amazon AWS S3 bucket?

AWS S3 , why it is S3 ? The name itself tells that its a 3 word whose alphabet starts with “S” . The Full form of AWS S3 is simple storage service. AWS S3 service helps in storing of unlimited data very safely and efficiently. There is a very basic architecture of AWS S3 . Everything in AWS S3 is a object such as pdf files, zip files , text files or war files anything. The next thing is bucket where all these objects resides.

AWS S3 Service  ➡️ Bucket  ➡️ Objects  ➡️ PDF , HTML DOCS, WAR , ZIP FILES etc.

Some of the features of AWS S3 bucket are:

  • In order to store the data in bucket you will need to upload it.
  • To keep your bucket permissions more secure provide necessary permissions to IAM role or IAM user.
  • Buckets have unique name globally that means there will be only 1 bucket throughout different accounts or any regions.
  • 100 buckets can be created in any AWS account , post that you need to raise a ticket to Amazon.
  • Owner of Bucket is specific to AWS account only.
  • Buckets are created region specific such as us-east-1 , us-east-2 , us-west-1 or us-west-2
  • Bucket objects are objected in AWS S3 using AWS S3 API service.
  • Buckets can be publicly visible that means anybody on the internet can access it. So it is always recommended to keep the public access blocked for all buckets unless very much required.


  1. AWS account to create S3 bucket. If you don’t have AWS account please create from AWS account or AWS Account
  2. Windows 7 or plus edition where you will execute the shell script.
  3. Python must be installed on windows machine which will be required by AWS cli. If you want to install python on windows machine follow here
  4. You must have Git bash already installed on your windows machine. If you don’t have install from here
  5. Code editor for writing the shell script on windows machine. I would recommend to use visual studio code on windows machine. If you wish to install visual studio on windows machine please find steps here

In this demo , we will use shell script to launch AWS S3 bucket. So In order to use shell scripts from your local machine that is windows you will require AWS CLI installed and configured. So First lets install AWS CLI and then configure it.

Install AWS CLI Version 2 on windows machine

  • Download the installed for AWS CLI on windows machine from here
  • Select I accept the terms and then click next button
  • Do custom setup like location of installation and then click next button
  • Now you are ready to install the AWS CLI 2
  • Click finish and now verify the AWS cli
  • Verify the AWS version by going to command prompt and type
aws --version

Now AWS cli version 2 is successfully installed on windows machine, now its time to configure AWS credentials so that our shell script connects AWS account and execute commands.

  • Configure AWS Credentials by running the command on command prompt
aws configure
  • Enter the details such as AWS Access key , ID , region . You can skip the output format as default.
  • Check the location on your system C:\Users\YOUR_USER\.aws file to confirm the the AWS credentials
  • Now, you’re AWS credentials are configured successfully.

How to launch or create AWS S3 bucket in Amazon account using shell script

Now we have configured AWS cli on windows machine , its time to create our shell script to create AWS S3 bucket.

  • Create a folder on your desktop and under that create file
#! /usr/bin/bash
# This Script will create S3 bucket and tag the bucket with appropriate name.

# To check if access key is setup in your system 

if ! grep aws_access_key_id ~/.aws/config; then
   if ! grep aws_access_key_id ~/.aws/credentials; then
   echo "AWS config not found or you don't have AWS CLI installed"
   exit 1

# read command will prompt you to enter the name of bucket name you wish to create 

read -r -p  "Enter the name of the bucket:" bucketname

# Creating first function to create a bucket 

function createbucket()
    aws s3api  create-bucket --bucket $bucketname --region us-east-2

# Creating Second function to tag a bucket 

function tagbucket()    {
   aws s3api  put-bucket-tagging --bucket $bucketname --tagging 'TagSet=[{Key=Name,Value="'$bucketname'"}]'

# echo command will print on the screen 

echo "Creating the AWS S3 bucket and Tagging it !! "
echo ""
createbucket    # Calling the createbucket function  
tagbucket       # calling our tagbucket function
echo "AWS S3 bucket $bucketname created successfully"
echo "AWS S3 bucket $bucketname tagged successfully "
  • Now open visual studio code and open the location of file and choose terminal as Bash
  • Now run the script
  • Script ran successfully , now lets verify the AWS S3 bucket by going on AWS account.
  • Click on the Bucket name testing-s3buck2 and then click on properties

  • Great we can see that tagging was also done successfully.


In this tutorial, we demonstrated some benefits of Amazon AWS S3 and learnt how to set up Amazon AWS S3 using shell script on AWS step by step . Most of your phone data and your website data are stored on AWS S3. This service specially to host a website is best in market.

Hope this tutorial will help you in understanding the shell script and provisioning the AWS S3 on Amazon cloud. Please share with your friends

  2. I have multiple aws accounts configured in my system. I named them Dev, Build & PROD.

    Can you suggest on how to configure your shell script to ask which profile/account to be used.

    Example: I want to create a S3 bucket in Build.
    – I run the script and as I have no default setup it throws the error (AWS config not found ….)

    What I need:
    – It needs to ask, which account you wanted to create the S3 bucket. (dev, build or prod)

    Thanks In advance.

    Thanks a lot. You page is helping a lot for me.
