Generating docker-compose files for microservices

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. 

Let's go to the base folder and create a folder and name it docker-compose:

> mkdir docker-compose && cd docker-compose

Once inside the docker-compose folder, we can run the following command:

jhipster docker-compose

This will generate the Dockerfiles.

As usual, it will ask us a series of questions, before generating the files:

At first, it asks which type of application we would like to deploy. We will select the microservice application as an option.

This is followed by choosing the type of gateway that we would like to use; there are two options available, a JHipster-gateway with Zuul proxy, and the more exciting, Traefik...
