Moving an API Endpoint to AWS Lambda

Lambda is a great way to manage APIs in the cloud. In this lab, we will be transitioning an existing Node.js/Express API to AWS Lambda. This will allow you to get hands-on with the process of creating and configuring APIs in Lambda!

  1. Challenge

    Package the Application Code

    Before starting the lab, ensure you download the ctaws-plant-shop code from the Github repository. There is already a Lambda-ready version of the code in that repository, in the directory api/lambda. You can use CloudShell to work with the code, and doing so will make it easy to deploy the code to the Lambda function later.

    You will need to download the dependencies, then package the code and dependencies in a .zip file.

  2. Challenge

    Create and Configure a Lambda Function

    Create a Lambda function called PlantShopAPI. This function should be accessible via a public URL with no need for authentication. It should also be connected to the default VPC, subnets, and the security group with the description Plant Shop Security Group.

    Deploy the packaged code to the function.

    You will also need to supply the following environment variables to allow the function code to connect to the existing RDS database:

    • DB_HOST - Paste in the RDS database endpoint
    • DB_USER - plantshop
    • DB_PASS - pl4nt5!
