aws-sts: Get temporary security credentials to access specific AWS resources.

$ aws sts assume-role --role-arn ${aws_role_arn}

try on your machine

The command "aws sts assume-role" is used to obtain temporary security credentials for a specific IAM role. This allows the user or AWS service to perform actions on their behalf while assuming the permissions defined by the IAM role.

Let's break down the command:

"aws sts" invokes the AWS Security Token Service (STS) command-line interface (CLI) command.
"assume-role" is the operation we want to perform with STS, which is to assume a role.
"--role-arn" is an option flag that specifies the Amazon Resource Name (ARN) of the role to assume. "${aws_role_arn}" is a placeholder for the actual ARN, which should be provided as a value. ARN is a unique identifier for AWS resources.
The actual command could be something like "aws sts assume-role --role-arn arn:aws:iam::123456789012:role/my-role".

When this command is executed, AWS STS authenticates the caller (normally using the caller's credentials) and checks if they have permission to assume the specified role. If authorized, STS generates a set of temporary security credentials, including an Access Key ID, Secret Access Key, and Session Token. These credentials are valid for a specified duration and can be used to make AWS API calls on behalf of the role.

These temporary credentials can be used to assume the permissions and access resources as defined by the IAM role.
