Docker is awesome, but it solves a problem that a simple monolith backend app that is built using one of the most popular frameworks simply doesn't have. If you're building an app with Node.js, then you could deploy it to EBS or Heroku or Digital Ocean as is — those tools (as well as many others) support Node.js (and many other frameworks) out of the box without any need for concretisation. The best piece of code is the code not written, and it applies to Dockerfiles to. Don't waste your time and mental space on something you don't really need.
