The AWS SAM CLI - AWS Serverless Application Model
How AWS SAM CLI commands are documented

The AWS SAM CLI

The AWS Serverless Application Model Command Line Interface (AWS SAM CLI) is the tool you use to run commands on your AWS SAM application project directory and eventually turn it into your serverless application. More specifically, the AWS SAM CLI allows you, build, transform, deploy, debug, package, initialize, and sync your AWS SAM application project directory.

The AWS SAM CLI and AWS SAM templates come with supported third-party integrations to build and run your serverless applications.

How AWS SAM CLI commands are documented

AWS SAM CLI commands are documented using the following format:

  • Prompt – The Linux prompt is documented by default and is displayed as ($ ). For commands that are Windows specific, (> ) is used as the prompt. Do not include the prompt when you type commands.

  • Directory – When commands must be executed from a specific directory, the directory name is shown before the prompt symbol.

  • User input – Command text that you enter at the command line is formatted as user input.

  • Replaceable text – Variable text, such as file names and parameters are formatted as replaceable text. In multiple-line commands or commands where specific keyboard input is required, keyboard input can also be shown as replaceable text. For example, ENTER.

  • Output – Output returned as a response to the command is formatted as computer output.

The following sam deploy command and output is an example:

$ sam deploy --guided --template template.yaml

Configuring SAM deploy

    Looking for config file [samconfig.toml] :  Found
    Reading default arguments  :  Success

    Setting default arguments for 'sam deploy'

  1. sam deploy --guided --template template.yaml is the command you enter at the command line.

  2. sam deploy --guided --template should be provided as is.

  3. template.yaml can be replaced with your specific file name.

  4. The output starts at Configuring SAM deploy.
