Node.js Microservices Deployed on EC2 Container Service

This is a reference architecture that shows the evolution of a Node.js application from a monolithic application that is deployed directly onto instances with no containerization or orchestration, to a containerized microservices architecture orchestrated using Amazon EC2 Container Service.

• Part One: The base Node.js application
• Part Two: Moving the application to a container deployed using ECS
• Part Three: Breaking the monolith apart into microservices on ECS

Common Errors

Encountered the below errors when building the Node.js microservices.

Solution to error:

aws configure set aws_session_token "<<your session token>>"
