How to work with Docker correctly?

Question

Virtualization

Good afternoon.
What is the best way to use Docker as a web developer?
Interested in whether to separate 1 project into different containers (eg nginx, php-fpm, mariadb as separate services) and manage via docker-compose or collect everything in 1? I am interested in this question because I see the combine in many projects. For me personally, it is more convenient to divide into services in order to easily change versions of services. Am I doing the right thing? What are the advantages and disadvantages of the second method, besides the fact that you have to rebuild the entire container?

Answer 1

About the "all in one" method: The
advantage is one: launched, it works.
Additional disadvantages:

• A bunch of processes in one container
  
• When transferring over the Internet in one piece (i.e. not from the LEMP-stack image), there will be problems with broken data
  
• The impossibility of scaling individual services (but here the complexity of work in the form of orchestration already increases)
