Initialize project

AWS SAM provides you with a command line tool, the AWS SAM CLI, that makes it easy for you to create and manage serverless applications. It particularly makes easy the scaffolding of a new project, as it creates the initial skeleton of a hello world application, so you can use it as a baseline and continue building your project from there.

Run the following command to scaffold a new project:

sam init

It will prompt for project configuration parameters:

Type 1 to select AWS Quick Start Templates

samInit

Type 12 to select the Java 8 runtime

samInit

Type 1 to select maven

samInit

Press enter to accept the default sam-app for project name

samInit

Type 1 to select the Hello World Example

samInit

This command supports cookiecutter templates, so you could write your own custom scaffolding templates and specify them using the location flag, For example: sam init –location git+ssh://git@github.com/aws-samples/cookiecutter-aws-sam-python.git.

Project should now be initialized

You should see a new folder sam-app created with a basic Hello World scaffolding. samInit
