Overview

The react "client" CFN docker template is complete, working, and able to be deployed to test (and production. We need to finish the CFN template and associated resources for setting up the api docker app.

Requirements

• In api.yml, finish creating the Task Definition and Service
• Create the SSM private key for test and production
• Create production Dockerfile and webpack configs
• Create the script to read/write encrypted keys from Parameter Store
• Create docker script to read the keys on start up and make available to express via ENV variables
• Create target group for API service, add listener rule for /api/*
• Create new Wildcard SSL certificate and use that as default value for SSL ARN for test.yml file
