Create an IAM User

Once we have an AWS account, we’ll need to create an IAM user to programmatically interact with it. We’ll be using this later to configure our AWS CLI (command-line interface).

Amazon IAM (Identity and Access Management) enables you to manage users and user permissions in AWS. You can create one or more IAM users in your AWS account. You might create an IAM user for someone who needs access to your AWS console, or when you have a new application that needs to make API calls to AWS. This is to add an extra layer of security to your AWS account.

In this chapter, we are going to create a new IAM user for a couple of the AWS related tools we are going to be using later.

Create User

First, log in to your AWS Console and search for IAM in the search bar. Hover or focus on the IAM card and then select the Users link.

Select Add Users.

Enter a User name, then select Next.

This account will be used by our AWS CLI and SST. They will be connecting to the AWS API directly and will not be using the Management Console.

Select Attach existing policies directly.

Search for AdministratorAccess and select the policy by checking the checkbox, then select Next.

We can provide a more fine-grained policy here. We cover this later in the Customize the Serverless IAM Policy chapter. But for now, let’s continue with this.

Select Create user.

Select View user.

Select Security credentials

Select Create access key

In keeping with the current guide instructions, we will choose other to generate an access key and secret. Select Other and select Next

You could add a descriptive tag here, but we will skip that in this tutorial, select Create access key

Select Show to reveal Secret access key.

Take a note of the Access key and Secret access key. We will be needing this in the next chapter.

Now let’s configure our AWS CLI. By configuring the AWS CLI, we can deploy our applications from our command line.
