So to start, let’s comment out all of the lines in this file by adding a “#” before each line.

How do you use Docker? etc.... Docker: 'A unique and smart way to build apps’, as stated on its website, is an open-source platform for building apps and micro-services. The catch here is the automated deployment of your app in a container, by OS level virtualization provided by Dockers. Dockers are better than VMs as you can do away with the additional costs for maintaining and starting the latter. By deploying your app and its dependencies (i.e. the per-requisite apps for its proper functioning) in a container, your app becomes portable during all the phases of development and testing. Moreover, the isolated apps eliminate conflicts, enable team collaboration, and reduce the time-to-market. When Do You Need to Use a Docker? For Docker CI/CD during numerous development phases (dev/te...
