The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4.

Microservices Architecture and Design patterns Available in doc link as well which have better formatting:  Microservices architecture and design patterns What are microservices?            In short, the microservice architectural style is an approach to developing a single application as a  suite of small services , each  running in its own process  and communicating with lightweight mechanisms, often an HTTP resource API.
