Configure AWS CLI Authentication

Goal

Configure AWS CLI authentication to deploy applications and access AWS resources.

Steps

1. Install AWS CLI

Download and install from the official AWS CLI documentation.

2. Create IAM User

Navigate to IAM service in AWS Management Console and create a new user with appropriate deployment permissions.

3. Generate Access Keys

In IAM user details → Security credentials tab → Create access key. Save the access key ID and secret access key.

4. Configure AWS CLI

Run the configuration command:

aws configure

Enter your credentials when prompted:

• Access key ID
• Secret access key
• Default region (e.g., us-east-1)
• Output format (e.g., json)

Alternative: manually edit ~/.aws/config (Linux/Mac) or %USERPROFILE%\.aws\config (Windows).

5. Verify Configuration

Test authentication by listing S3 buckets:

aws s3 ls

If configured correctly, you’ll see your S3 buckets listed.
