The project is not able to run without using many computers or cloud environment

If you try to start the containerized version of docker:

npm run java:docker
docker compose -f src/main/docker/app.yml up -d

listen tcp 127.0.0.1:5432: bind: address already in use

It tries to launch 2 instances of PostgreSQL since the gateway includes the definition of docker container for PostgreSQL but for each microservice if uses the same database engine you will have another docker container definition.

So 1 gateway and 4 services with MySQL would result in a conflict for port 3306 since there is no docker network defined and all ports are binded to the same in the host OS.

Motivation for or Use Case

The application will not works in container mode for microservice JDL since gateway + N services will conflict same port for databases of each component.

Reproduce the error
  1. nvm use 20.12.2
  2. jhipster jdl microservice.jdl
  3. cd mygateway
  4. npm run java:docker
  5. docker compose -f src/main/docker/app.yml up -d
  6. Enjoy.

If you try to remove mysql.yml containers and references in all configuration files you will got exception perhaps because is hard-coded somewhere ???

#27685

Suggest a Fix

Make appropriate docker network and make sure bind different ports to the host OS example: mysql 1 : 3307 , mysql 2: 3308 , etc ...

Also I suggest do not close issues that are reported and not solved.

Just to make sure, do you want to use it without any usage of docker or do you want the default docker config to be working with multiple services using the same database? As in your other ticket it sounded like docker has been the problem.

In previous versions of Jhipster you decide if use docker or not, you can launch: database, registry, control center, anything you need.


Anyway if use docker with microservice will be a conflict with the port if many services including gateway use same database engine: listen tcp 127.0.0.1:5432: bind: address already in use.


I'm missing the use case of JHipster ? how do you do if have multiple microservices in your local environment ? Regardless if you run everything in containers it shouldn't have port conflicts. And setup to use local database should be easy, currently is very coupled to docker containers.

You can still do that. The default docker configs have always used fixed ports (the default port of the database) so it can be switched to a non containerized database without any changes to the application config. With the new compose support by spring boot we can enhance it and remove the fixed port bindings and let boot auto discover the used port. But in case you want to use a local database you would have to configure the services, thats why we have a fixed port binding for now (which is not perfect, but considered using different dbs for each service it worked pretty well).
