Overview¶

What is AWS CLI?¶

The AWS Command Line Interface (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.

Common Use Cases include managing AWS resources through the command line, automation deployments via CI/CD pipelines, and script integrations.

The AWS CLI is a good back up tool to have, although we will not be interfacing too much with it throughout CA101.

Install AWS CLI¶

Windows¶

MSI Installer¶

Download the AWS CLI MSI installer:
Visit: https://awscli.amazonaws.com/AWSCLIV2.msi

Configure AWS CLI¶

After installing AWS CLI, you need to configure it with your AWS credentials.

Prerequisites¶

You'll need a AWS Access Key ID and AWS Secret Access Key for projectx-prod-admin IAM user account.

👉 To create access keys, go to IAM ➔ Users ➔ Your User ➔ Security Credentials ➔ Create Access Key.

Configuration Steps¶

Run the configure command:

aws configure

You'll be prompted for the following:

AWS Access Key ID: Enter your access key ID
```
AWS Access Key ID [None]: E
```
AWS Secret Access Key: Enter your secret access key
```
AWS Secret Access Key [None]: 
```
Default region name: Enter your preferred AWS region
```
Default region name [None]: us-east-2
```
Default output format: Choose your preferred output format (optional)
```
Default output format [None]: Leave blank
```

Common formats: json, yaml, text, table

Configuration File Location¶

AWS CLI stores your credentials and configuration in:

Windows:

C:\Users\YourUsername\.aws\credentials
C:\Users\YourUsername\.aws\config

macOS/Linux:

~/.aws/credentials
~/.aws/config

Verify Configuration¶

Test your configuration:

# List your AWS account information
aws sts get-caller-identity

# List S3 buckets (if you have any)
aws s3 ls

# List EC2 instances
aws ec2 describe-instances

👉 If you see your account information, your AWS CLI is configured correctly!
