Micro Service based Http Book Store Rest API built using GOLANG, DOCKER, KUBERNETES)

• The goal is to build Micro Service based Http Book Store Rest API, containerize it using Docker and finally orchestrate using Kubernetes

• The project was developed using GOLANG | DOCKER | KUBERNETES

Using Go internal libraries developed a HTTP server

Json marshaling and unmarshaling of books

book rest api

containerize it using docker work flow

making use of docker compose to compose micro service with few other containers.

orchestrate go micro service by scaling it horizantallly using kubernetes

finally did rolling upgrade of go micro service

In order to build and run this showcase you need to have a couple of things installed:

The Go SDK (e.g. using Brew)

An IDE for the development, like Visual Studio Code or IntelliJ

The Docker Toolbox or native Docker, whatever you prefer
