Hi! We are back to another post in PPL series. Here, I will explain about how our team build small and efficient docker image that is used to ship and deploy our server side application. Our server side application is Django-based app. So this article can also serve as reference on how to build another similar python based server side application. I will skip most of the container vs VM explanation. So, you are expected to be already familiar with docker fundamental concepts such as container, container image, its layers, and container registry.
