AWS-CLI Command Line Interface for Amazon AWS Administration

1. Introduction

The AWS Command Line Interface 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.

2. Basic explanation

2.1. Installing

• To install AWS Command Line Interface in your Windows Operational System, download appropriated binary files: 64 bits or 32 bits
• To install AWS Command Line Interface in your Linux or Mac, use pip command: Python is required

2.2. Configure AWS-CLI with your account information - Windows

• Step #1: Get your AWS account information: aws_access_key_id, aws_secret_access_key, aws_security_token
• Step #2: Configure your default AWS-CLI

C:\Users\Josemar Silva>aws configure

AWS Access Key ID [None]: **************

AWS Secret Access Key [None]: ******************************************

Default region name [None]: sa-east-1

Default output format [None]: text

• Step #3: Test your AWS-CLI listing all EC2 machines:

C:\Users\Josemar Silva>aws ec2 describe-instances

RESERVATIONS 918139315827 r-5f281c43

GROUPS sg-0bd36d16 awssrv003

• Step #4: Test your AWS-CLI listing all bucktes from S3:

C:\Users\Josemar Silva>aws s3 ls s3://
C:\Program Files\Amazon\AWSCLI\.\dateutil\parser.py:339: UnicodeWarning: Unicod
 equal comparison failed to convert both arguments to Unicode - interpreting th
m as being unequal
2014-01-02 22:54:07 my-backet

• Step #5: Test copy something to your S3 bucktes:

C:\Users\Josemar Silva>aws s3 cp lixo.txt s3://my-backet/area_backup
upload: .\lixo.txt to s3://my-backet/area_backup
