  • To ensure compatibility between local, development, staging, test and production environments, the use of Docker is encouraged
  • Docker Compose should be used when there are multiple services running, like NodeJS and PostgreSQL
  • Always prefer 2 smaller containers over 1 larger one
  • Usage of Linux Alpine is prefered, because it is a very light distro and will speed things up a lot
  • Try not to create complete Dockerfile install scripts, rather use existing (and verified safe!) Docker images from the Docker Hub
  • The docker-compose.yml file should be the same between environments, so no -prod.yml, -dev.yml files
  • GitLab can be used as container registry
