Creating your first microservice

A microservice is just a piece of code that runs as a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal, which we will be writing in this recipe using https://github.com/micro/micro though there are a number of libraries available such as https://github.com/go-kit/kit and https://github.com/grpc/grpc-go, which serve the same purpose.

Getting ready...

$ consul agent -dev

$ go get github.com/micro/micro
