Should I use separate Docker containers for my web app?

Question

Do I need use separate Docker container for my complex web application or I can put all required services in one container? Could anyone explain me why I should divide my app t

Answer 1

When you divide your web application to many containers, you don't need to restart all the services when you deploy your application. Like traditionally you don't restart your mysql server when you update your web layer.

Also if you want to scale your application, it is easier if your application is divided separate containers. Then you can just scale those parts of your application that are needed to solve your bottlenecks.
