To see the Serverlesspresso workshop, visit: https://workshop.serverlesscoffee.com/. In this workshop, you will deploy a serverless backend that supports a pop-up coffee shop. You will then test your application using 3 front-end applications that are provided.

Installing the backend

For all of the deployments, use us-east-1 for Region when prompted.

1. Installing the core stack

This create a custom event bus, custom SMS auth flow for Cognito signin, and other foundational resources used by other services.

1. From the command line, install the realtime messaging stack:

cd /00-baseCore
sam build
sam deploy --guided

During the prompts, enter serverlesspresso-core for the Stack Name, core for Service, and accept the defaults for the remaining questions.

2. After installation, note the outputs section, which provides the UserPoolID, bus name and ARN, IoT endpoint, and user pool client name. These outputs are also stored in AWS Systems Manager Parameter Store for the subsequent SAM stacks to use.

2. Install microservices

cd /01-appCore
sam build
sam deploy --guided

During the prompts, enter serverlesspresso for the Stack Name.

Cleaning up

1. Navigate to the AWS CloudFormation console.
2. Delete each stack that starts with serverlesspresso.
