Dockers

It reminds me of how I learned to use Docker in the good old days. When testing codes in different devices, it was a nightmare for setting up environments, and the Docker image can save your life. It is simply a container that allows you to move the whole file with its setting, config files together, and in few clicks, you can recreate the system entirely. As time passed, there were more techniques coming out, and it saved a lot of time. Also, how to manage those containers became a problem, and we can discuss about this in the future,
