Working with AWS Cloud from CommandLine — Part1

In this article, we will understand how to setup aws cli in a system to work with AWS Cloud from Command line.

To work with aws cli through command line, first, we are required to create an IAM user. Then, the IAM user created will be assigned suitable powers or permissions, that will allow him to interact with AWS Cloud.

Also, below steps are same for Windows and for any Linux Operating system. So you can choose any OS to work on.

Step 1: Creating an IAM User:

For this Step, we will be using the AWS GUI:

Step 1: Open the IAM service, present under Security, Identity and Compliance.

Step 2: Click on Users.

You will be redirected to this page, where we have an option to add user.

Step 3: Click on Add user.

• Specify the IAM user name,
• Enable both the access type.
  Programmatic Access allows this user to interact with AWS cloud using non-GUI methods such as CLI or SDK.
  AWS Management console access is to allow this user to use the AWS GUI.
• Specify a custom password.
• Uncheck the Required Password Reset.

After this click on Next: Permissions.

Step 4: Setting up the Permissions for this user.

We will be assigning predefined Policy to this user: PowerUserAccess. In this policy, a user is allowed to interact with all the services of aws cloud except Billing and IAM user.
