There are many docker-compose files and maintaining them is hard. Thankfully, JHipster has a docker-compose sub generator bundled with it. The Docker-compose sub generator helps you to organize all your application's Dockerfiles together. It creates a single Dockerfile that refers to the application's Dockerfiles.
