We will use an example of an Angular 9 app, Node.js REST API backend and a Postgres database. We will orchestrate this system with Docker swarm and deploy it using Ansible. This will allow us to deploy, update and rollback the system with a single command. We will also use nginx-proxy as an entry point to the application and letsencrypt-nginx-proxy-companion to automate SSL certificates.

I also provide boilerplate code for dockerized Wordpress.

In Javascript, we sometimes create functions that accept objects, which can be more convenient, but this sacrifices readability of the function header. In this blog post I present ES6 object destructuring as a solution to this problem.
