AWS CLI is available in GitHub: https://github.com/aws/aws-cli/releases.

Installation

  • Linux installation from Amazon:
apt install -y curl unzip
curl -sS "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip -q awscliv2.zip
sudo ./aws/install

AWS CLI configuration

First you will need to configure your AWS CLI access: aws configure or aws configure --profile your-new-profile-name. You will be prompted to enter a username and password. Configuration will be saved in directory $HOME/.aws/ in files credentials and config.


Execute aws configure list to view your actual configuration. If you execute for the first time will be something like:

 aws configure list
     Name                    Value             Type    Location
     ----                    -----             ----    --------
  profile                <not set>             None    None
  access_key             <not set>             None    None
  secret_key             <not set>             None    None
  region                 <not set>             None    None

If you have multiple profiles defined you can list them:

  • ~/.aws/config
  • ~/.aws/credentials
  • ~/.aws/cli/alias

Basic AWS EC2 commands [2]

Before starting to use AWS CLI you will need to configure IAM policies for your user.

  • Get a list of EC2 instances:
aws ec2 describe-instances
  • Get a list of EC2 instances and filter Name, Id and Status:
aws ec2 describe-instances | egrep 'InstanceId|"Name":|"Value":|PublicIp'
  • Create or run an instance
aws ec2 run-instances [3]
  • Start an EC2 instance:
aws ec2 start-instances --instance-ids i-08cf893bbcfd7dc46 (Use your own instance-id)
  • Stop an EC2 instance:
aws ec2 stop-instances --instance-ids i-08cf893bbcfd7dc46 (Use your own instance-id)
  • Show Relational Database Service (RDS) instances:
aws rds describe-db-instances
  • Query and display EC2 metadata: ec2metadata [4] (Distributed in cloud-guest-utils package at least in Debian)

Basic AWS S3 commands

  • List your buckets: aws s3api list-buckets
  • List your buckets in all regions:
for region_name in ap-south-1 eu-west-3 eu-west-2 eu-west-1 ap-northeast-2 ap-northeast-1 sa-east-1 ca-central-1 ap-southeast-1 ap-southeast-2 eu-central-1 us-east-1 us-east-2 us-west-1 us-west-2; do 
   aws s3api list-buckets --region $region_name
done
If you do not have permisssions you will get the following error:
An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied
  • aws s3 ls your_bucket_name
  • aws --profile your_profile_name s3 ls your_bucket_name (You can also use a profile to define your credentials)
  • aws s3 cp[5]
  • Size of a Bucket: aws s3 ls --summarize --human-readable --recursive s3://bucket-name/ [6]
