aws-cli

Description

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.

The AWS CLI introduces a new set of simple file commands for efficient file transfers to and from Amazon S3.

Supported Services

For a list of the available services you can use with AWS Command Line Interface, see Available Services in the AWS CLI Command Reference.

AWS Command Line Interface on GitHub

You can view—and fork—the source code for the AWS CLI on GitHub in the https://github.com/aws/aws-cli project.

AWS completer for Ubuntu with Bash#

The following utility can be used for auto-completion of commands:

$ which aws_completer
/usr/bin/aws_completer

$ complete -C '/usr/bin/aws_completer' aws

For future shell sessions, consider add this to your ~/.bashrc

$ echo "complete -C '/usr/bin/aws_completer' aws" >> ~/.bashrc

To check, type:

$ aws ec

Press the [TAB] key, it should add 2 automatically:

$ aws ec2

Creating a New Profile#

To setup a new credential profile with the name myprofile :

$ aws configure --profile myprofile
AWS Access Key ID [None]: ACCESSKEY
AWS Secret Access Key [None]: SECRETKEY
Default region name [None]: REGIONNAME
Default output format [None]: text | table | json

For the AWS access key id and secret, create an IAM user in the AWS console and generate keys for it.

Region will be the default region for commands in the format eu-west-1 or us-east-1 .

The default output format can either be text , table or json .

You can now use the profile name in other commands by using the --profile option, e.g.:

$ aws ec2 describe-instances --profile myprofile

AWS libraries for other languages (e.g. aws-sdk for Ruby or boto3 for Python) have options to use the profile you create with this method too. E.g. creating a new session in boto3 can be done like this, boto3.Session(profile_name:'myprofile') and it will use the credentials you created for the profile.

The details of your aws-cli configuration can be found in ~/.aws/config and ~/.aws/credentials (on linux and mac-os). These details can be edited manually from there.

Installation and setup#

There are a number of different ways to install the AWS CLI on your machine, depending on what operating system and environment you are using:

On Microsoft Windows – use the MSI installer. On Linux, OS X, or Unix – use pip (a package manager for Python software) or install manually with the bundled installer.

Install using pip:

You will need python to be installed (version 2, 2.6.5+,3 or 3.3+). Check with

python --version

pip --help

Given that both of these are installed, use the following command to install the aws cli.

sudo pip install awscli

Install on Windows The AWS CLI is supported on Microsoft Windows XP or later. For Windows users, the MSI installation package offers a familiar and convenient way to install the AWS CLI without installing any other prerequisites. Windows users should use the MSI installer unless they are already using pip for package management.

Run the downloaded MSI installer. Follow the instructions that appear.

To install the AWS CLI using the bundled installer

Prerequisites:

  • Linux, OS X, or Unix
  • Python 2 version 2.6.5+ or Python 3 version 3.3+
  1. Download the AWS CLI Bundled Installer using wget or curl.
  2. Unzip the package.
  3. Run the install executable.

On Linux and OS X, here are the three commands that correspond to each step:

$ curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
$ unzip awscli-bundle.zip
$ sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

Install using HomeBrew on OS X:

Another option for OS X

brew install awscli

Test the AWS CLI Installation

Confirm that the CLI is installed correctly by viewing the help file. Open a terminal, shell or command prompt, enter aws help and press Enter:

$ aws help

Configuring the AWS CLI

Once you have finished the installation you need to configure it. You’ll need your access key and secret key that you get when you create your account on aws. You can also specify a default region name and a default output type (text|table|json).

$ aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: ENTER

Updating the CLI tool

Amazon periodically releases new versions of the AWS Tool. If the tool was installed using the Python Pip tool the following command will check the remote repository for updates, and apply it to your local system.

$ pip install awscli --upgrade

List S3 buckets#

aws s3 ls

Use a named profile

aws --profile myprofile s3 ls

List all objects in a bucket, including objects in folders, with size in human-readable format and a summary of the buckets properties in the end –

aws s3 ls --recursive --summarize --human-readable s3://<bucket_name>/

Using aws cli commands#

The syntax for using the aws cli is as follows:

aws [options] <command> <subcommand> [parameters]

Some examples using the ‘ec2’ command and the ‘describe-instances’ subcommand:

aws ec2 describe-instances

aws ec2 describe-instances --instance-ids <your-id>

Example with a fake id:

aws ec2 describe-instances --instance-ids i-c71r246a
