Cannot connect to jhipster spring registry on docker via IDE

I'm running JHipster registry in a docker container. All applications running on docker can connect and register in registry endpoint (port 8761).

But when I try to connect an application running on my IDEA, I receive a error when trying to connect to the registry endpoint:

The application connects to Register (see it in logs), but after that I receive the error:

UnknownHostException: registry

Did anyone know how can I connect to a registry running in docker?

My spring application.yml is:

eureka:
    instance:
        prefer-ip-address: true
    client:
        enabled: true
        healthcheck:
            enabled: true
        registerWithEureka: true
        fetchRegistry: true
        serviceUrl:
            defaultZone: http://admin:admin@localhost:8761/eureka/

The default zone in jhipster-registry is http://user:pass@register:8761/eureka.

If I change to localhost, like this:

eureka:
    client:
        serviceUrl:
            defaultZone: http://admin:admin@localhost:8761/eureka/

It works, but in this case the services running in docker can't access the registry (reverse problem).

Thanks!

The localhost on docker which running microservice is not the same localhost on docker which running registry. I changed the localhost to the host's Intranet Address, It's work for me.

eureka:
    instance:
        prefer-ip-address: true
    client:
        service-url:
            defaultZone: http://admin:${jhipster.registry.password}@10.31.224.228:8761/eureka/

I had a similar issue. In 3.5.0, I was able to successfully start the docker based registry, and then start up non docker versions of a microservice and a gateway. With 3.5.1, I was no longer able to do that, getting the same error you are getting. I think it's related to https://github.com/jhipster/generator-jhipster/pull/3848. In any case, I just added an entry in my /etc/hosts file, pointing "registry" to 127.0.0.1, and it worked.
