Preparation

To start building SAM-based applications, we must first install the SAM CLI, install the AWS credentials, and initialize a simple SAM application.

  1. Install SAM CLI for OS:
  • MacOS
brew tap aws/tap
brew install aws-sam-cli
sam --version
  • Linux
pip install aws-sam-cli
sam --version
  • Windows
    • Downloads AWS SAM CLI 64-bit
    • Install file and check version of SAM
sam --version

You can refer to: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html

  1. If you have already installed AWS credentials from previous posts, you can skip this step.

IAMConsole

  • Click User on the left menu.
  • Click Create user button

IAMConsole

  • Enter user name, such as: AdminSAMUser
  • Select Password - AWS Mannagemant Console access of Select AWS credentail type pattern
  • Select Custom password, then enter your password
  • Uncheck the Require password reset
  • Click Next: Permissions

IAMConsole

  • Select Attach existing policies directly
  • Select AdministratorAccess policy to the user has full access to the services
  • Click Next: Tags

IAMConsole

  • Click Next: Review
  • Review configuration, and click Create user

IAMConsole

  • Click on the newly created user.

IAMConsole

  • Click Security credentials tab
  • Click Create access key

IAMConsole

  • Click Download .csv file

IAMConsole

  • Run the command using the terminal on your device
aws configure
  • Enter the information corresponding to the columns in the credential file you downloaded
    • AWS Access key ID: Enter access key ID
    • AWS Secret access key: Enter secret access key
    • Default region name: Enter region closest to you
    • Default output format: Can be overlooked
  1. Then, create a sample SAM project
  • Run the below commands at the directory where you want to deploy the application
#Step 1 - Download a sample application
sam init
  • Then select the options:
Which template source would you like to use?
	1 - AWS Quick Start Templates
	2 - Custom Template Location
Choice: 1

Choose an AWS Quick Start application template
	1 - Hello World Example
	2 - Multi-step workflow
	3 - Serverless API
	4 - Scheduled task
	5 - Standalone function
	6 - Data processing
	7 - Infrastructure event management
	8 - Machine Learning
Template: 1

Use the most popular runtime and package type? (Python and zip) [y/N]: y

Would you like to enable X-Ray tracing on the function(s) in your application?  [y/N]: n

Project name [sam-app]:  fcj-book-store

IAMConsole

You have created a sample SAM project. Next , we will edit that project according to our application architecture.
