Why CLI matters for automation in AWS - See It in Action

Why CLI Matters for Automation

📖 Scenario: You are working as a cloud engineer for a small company. Your team wants to automate the creation of cloud resources to save time and avoid mistakes. You will learn how using the AWS Command Line Interface (CLI) helps automate tasks easily and reliably.

🎯 Goal: Build a simple AWS CLI command script that creates an S3 bucket automatically. This will show how CLI commands can be used in automation scripts to manage cloud resources.

📋 What You'll Learn

Create a variable with the exact bucket name

Add a configuration variable for the AWS region

Write the AWS CLI command to create the S3 bucket using the variables

Add the final command option to enable versioning on the bucket

💡 Why This Matters

🌍 Real World

Cloud engineers use AWS CLI scripts to automate creating and managing cloud resources quickly and without errors.

💼 Career

Knowing AWS CLI automation is essential for cloud jobs to improve efficiency and reduce manual work.

1

Create the bucket name variable

Create a variable called bucket_name and set it to the exact string my-automation-bucket-123.

AWS

# Your code here

Need a hint?

Use double quotes around the bucket name string.

2

Add the AWS region configuration

Create a variable called region and set it to the exact string us-west-2.

AWS

bucket_name="my-automation-bucket-123"
# Your code here

Need a hint?

Use double quotes around the region string.

3

Write the AWS CLI command to create the bucket

Write the AWS CLI command to create an S3 bucket using aws s3api create-bucket. Use the variables bucket_name and region exactly as shown. Include the option --bucket with $bucket_name and --region with $region. Also include --create-bucket-configuration LocationConstraint=$region.

AWS

bucket_name="my-automation-bucket-123"
region="us-west-2"
# Your code here

Need a hint?

Use the exact AWS CLI syntax with the variables.

4

Enable versioning on the bucket

Add the AWS CLI command to enable versioning on the bucket. Use aws s3api put-bucket-versioning with --bucket $bucket_name and --versioning-configuration Status=Enabled.

AWS

bucket_name="my-automation-bucket-123"
region="us-west-2"
aws s3api create-bucket --bucket $bucket_name --region $region --create-bucket-configuration LocationConstraint=$region
# Your code here

Need a hint?

This command turns on versioning so you can recover old files.
