Terraform template to create an AWS API Gateway taht accepts GET and POST requests to trigger one of two Lambda functions to update or access a small NoSQL AWS DynamoDB Database.

Download and Install Terraform

Download and Install AWS CLI After you have installed AWS CLI, use your terminal to configure your AWS credentials:

aws configure

If you are using this project independently, please either comment out the terraform block that begins on line 5 of serverless.tf, or change the bucket parameter to reference an S3 bucket that you have access to with your AWS credentials.

terraform init
terraform apply

Follow the prompts from these commands and as long as you have the correct permissions on your AWS credentials, the environment should launch successfully.

Using the AWS Console, navigate to the API Gateway service. Try this sample data to test the Create User function:

{
    "body": {"Username":"snowdogg","GovtName":"Andreas Cary"}
}

There is no data required to test the Get User function. Just use the test feature after adding the above data to the database and it should return your new database entry.

Creates a VPC with 2 public and 2 private subnets, an internet gateway and a nat gateway.

Creates two lambda functions: one to create an entry in the database and one to fetch all the entries in the database. These lambda functions can exist across the two private subnets for high availability.

Master key is Username, sort key is GovtName. Example entry: Username: "snowdogg", GovtName: "Andreas Cary"

Creates an API Gateway which receives GET requests and forwards them to the Get Users lambda function, and also receives POST requests and forwards them to the Create User lambda function.
