100 Days of AWS — Day 22- Introduction to AWS CLI

What is AWS CLI?

The AWS Command Line Interface (AWS CLI) is a unified tool that provides a consistent interface for interacting with all parts of AWS.

The AWS CLI is an open source tool built on top of the AWS SDK for Python (Boto) that provides commands for interacting with AWS services. With minimal configuration, you can start using all of the functionality provided by the AWS Management Console from your favorite terminal program.

# yum -y install python34-pip.noarch
# pip3 install awscli
# pip3 install awscli --upgrade
# aws --versionaws-cli/1.18.147 Python/2.7.18 Linux/5.10.106-102.504.amzn2.x86_64 botocore/1.18.6
# aws configureAWS Access Key ID [None]: XXXXXXXXAWS Secret Access Key [None]: XXXXXXXXDefault region name [None]: us-west-2Default output format [None]: json
# aws <command> <option> --output text
eg:
# aws ec2 describe-instances --output text
# aws <command> <option> --output table
eg:
# aws ec2 describe-instances --output table

The AWS CLI signs requests on your behalf, and includes a date in the signature. Ensure that your computer’s date and time are set correctly; if not, the date in the signature may not match the date of the request, and AWS rejects the request.
