Configure AWS CLI

This article is for those looking for a detailed and straightforward guide on configuring AWS CLI.

The AWS CLI is a single tool for managing AWS services. With just one tool download, you can control many AWS services from the command line and automate them with scripts.

IMPORTANT

In this guide, we will consider the case when you already have an operating system with AWS CLI installed on it.

For detailed instructions on installing the AWS CLI on macOS, see my guide: Install AWS CLI on macOS.

We need to create a new user and assign him an access policy. The user will be used to connect to AWS using AWS CLI.

Log in under your root account on AWS and search for “IAM” in the main search bar on top of the AWS dashboard.

Go to the “Users” section and click on the “Add users” button.

In the “User name” field, specify the username for the new user and check “Access key - Programmatic access”.

NOTE

In this manual, “vladimir_mikhalev” will be used as the username.

Click on the “Next: Permissions” button.

Next, select “Attach existing policies directly”.

Select the “AdministratorAccess” policy and Click on the “Next: Tags” button.

In the next step, you do not have to make any changes.

Click on the “Next: Review” button.

Everything is ready to create a new user.

Click on the “Create user” button.

The user has been successfully created and has the necessary permissions.

Now you need to save the received “Access key ID” and “Secret access key”.

Click on the “Show” button to display the contents of the “Secret access key” section and save the contents of the section to a safe place.

Click on the “Close” button.

Let’s configure AWS CLI with the command:

1
aws configure

In the “AWS Access Key ID” field, specify the access key ID that you obtained earlier during user creation.

Press the “Enter” button.

In the “AWS Secret Access Key” field, specify the secret access key that you obtained earlier during user creation.

Press the “Enter” button.

In the “Default region name” field, specify the AWS region in which you are planning to work.

Press the “Enter” button.

In the “Default output format” field, specify “json” as a format.

Press the “Enter” button.

Everything is ready to use the AWS CLI.

Let’s list all EC2 instances with the command:

1
aws ec2 describe-instances

Please note that I have just one EC2 instance.

Now press the “q” button to close information about EC2 instances.
