Eureka won't connect when run jhipster-registery in docker with cloud config server

[Chipsona]

Hi All,
I am new to jhipster and docker. Just creating a jhipster-registry instance on linux server using docker. I am getting below exception

jhipster-registry_1 | 2022-05-18 09:20:35.839 INFO 1 --- [ main] c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://admin:admin@localhost:8761/eureka/}, exception=java.net.ConnectException: Connection refused (Connection refused) stacktrace=com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused (Connection refused)

It also shows Jhipster-registry instand as DOWN on dashboard

I have downloaded the jhipster registry image and created created a container using docker-compose command. I am using GIT repo for config server.

Command : docker-compose -f jhipster-registry.yml up

  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://admin:admin@localhost:8761/eureka/

It won't throw error when I set value to false for below property . But it won't register any microservices.

register-with-eureka: false
fetch-registry: false

Kindly help and let me know what is wrong with above configuration.

Last time I used it, I registered my local url as 127.0.0.1 jhipster-registry in my /etc/hosts and it worked. Can you please try it?

Thanks @Tcharl for your response. I have tried this but no luck.

[Tcharl]

You should also modify the service url in your compose file right?

[Chipsona]

http://admin:${jhipster.registry.password}@jhipster-registry:8761/eureka/

yes @Tcharl . I did that. like below
http://admin:admin@jhipster-registry:8761/eureka/

Error-

--- [ main] c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://admin:admin@jhipster-registry:8761/eureka/}, exception=java.net.ConnectException: Connection refused (Connection refused) stacktrace=com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused (Connection refused)

Eureka instance shows DOWN on jhipster registry dashboard.

I have tried with following property
register-with-eureka: false
fetch-registry: false

but in this case microservices wont get registered and Eureka server also wont start I think.

Here's what I had on my side for local environment (I'll retest with another example in the latest version as soon as I can).

Thanks @Tcharl for you prompt response.
The issue occurs when I use "Spring Cloud Config" from GIT repo using PROD profile. Kindly check section - Config-server : application.yml at GIT repo above

At local Dev profile with "central-config" works fine.

Could you check jhipster-registry.yml and config-server application.yml above and let me know if I am missing anything.

Thanks.
