I'm currently learning how to use docker or containerization with gitlab pipeline. Why? I want to know the best way of how one can automate deployment of production ready website. Previously, I've to do a lot of setup on the server itself. Now, I just need to install docker & import any environment files use on the web itself. Other than that, all are being configured using docker. Much neater right? I'm really glad I've a great seniors that don't mind sharing what they know with me. If not, it will take much longer time before I can actually use this method on my own project.
