Passing data between Terraform and Serverless with SSM Parameters
- Access to an AWS account.
aws-cliis installed and configured (see AWS CLI docs for specific configuration steps).
- Terraform is installed (see the Terraform website for instructions).
- Serverless is installed (see the Getting Started guide).
Deploying the infrastructure
- Deploy the Terraform infrastructure:
cd terraform terraform init terraform apply
- Deploy the Serverless project:
cd ../serverless serverless deploy serverless info --verbose | grep ServiceEndpoint | sed s/ServiceEndpoint\:\ //g # Gets Endpoint URL
<ENDPOINT>?name=<VALUE_TO_ADD>in your browser.
terraform directory defines a small set of infrastructure elements: a VPC, the subnets, a security group, and an RDS MySQL database. The key there is the
parameters.tf file that defines the SSM parameters and populates them with the information about the database.
serverless directory contains a simple Serverless Framework project. The function invoked via an HTTP call takes a
name query param. It inserts the param into the DB and renders the whole table. The function assumes that the table called
things exists. There is no validation on the
name param, so be creative!
