The deployment of a serverless web application requires the use of an account on the target cloud service provider. The use of such services may generate costs at the end of the month depending on your use. That’s why, you will have to fill your credit card number when creating a cloud provider account. Don’t worry, daSWAG makes maximum use of free tier services, allowing you to use your application in development and integration environments with complete peace of mind.
For further read, I invite you to check the site: AWS Free Tier and look at the pricing model of each of the services used to have a better understanding of your possibilities and the price it will cost.
For general use, the aws configure command is the fastest way to set up your AWS CLI installation.
$ 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]: json
When you type this command, the AWS CLI prompts you for four pieces of information (access key, secret access key, AWS Region, and output format). These are described in the following sections. The AWS CLI stores this information in a profile (a collection of settings) named default. The information in the default profile is used any time you run an AWS CLI command that doesn’t explicitly specify a profile to use.
The AWS Access Key ID and AWS Secret Access Key are your AWS credentials. They are associated with an AWS Identity and Access Management (IAM) user or role that determines what permissions you have. For a tutorial on how to create a user with the IAM service, see Creating Your First IAM Admin User and Group in the IAM User Guide.
Access keys consist of an access key ID and secret access key, which are used to sign programmatic requests that you make to AWS. If you don’t have access keys, you can create them from the AWS Management Console. As a best practice, do not use the AWS account root user access keys for any task where it’s not required. Instead, create a new administrator IAM user with access keys for yourself.
The only time that you can view or download the secret access key is when you create the keys. You cannot recover them later. However, you can create new access keys at any time. You must also have permissions to perform the required IAM actions. For more information, see Permissions Required to Access IAM Resources in the IAM User Guide.
To create access keys for an IAM user
Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.
In the navigation pane, choose Users.
Choose the name of the user whose access keys you want to create, and then choose the Security credentials tab.
In the Access keys section, choose Create access key.
To view the new access key pair, choose Show. You will not have access to the secret access key again after this dialog box closes. Your credentials will look something like this:
Access key ID: AKIAIOSFODNN7EXAMPLE
Secret access key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
To download the key pair, choose Download .csv file. Store the keys in a secure location. You will not have access to the secret access key again after this dialog box closes. Keep the keys confidential in order to protect your AWS account and never email them. Do not share them outside your organization, even if an inquiry appears to come from AWS or Amazon.com. No one who legitimately represents Amazon will ever ask you for your secret key.
After you download the .csv file, choose Close. When you create an access key, the key pair is active by default, and you can use the pair right away.
The Default region name identifies the AWS Region whose servers you want to send your requests to by default. This is typically the Region closest to you, but it can be any Region. For example, you can type us-west-2 to use US West (Oregon). This is the Region that all later requests are sent to, unless you specify otherwise in an individual command.
You must specify an AWS Region when using the AWS CLI, either explicitly or by setting a default Region. For a list of the available Regions, see Regions and Endpoints. The Region designators used by the AWS CLI are the same names that you see in AWS Management Console URLs and service endpoints.
