I've looked over most of the documentation provided, couldn't find an absolute answer about changing jhipster-registry port, it's default is 8761, but when I try to chnage it's port through YAML config file it gets indeed working in that port but both the gateway and microservice cannot be found by the registry. am i doing anything wrong ? is jhipster-registry bound to remain intact when it comes to port manipulation ?
You must change port in spring.cloud.config.uri in all application's bootstrap*.yml so they can retrieve their config from the registry and also change it in eureka.client.defaultZone in application.yml in jhipster-registry's central-config folder if you use file system backend or in git repo if you use git backend.
This is because the registry is both a Spring Cloud Config server and an Eureka server. In JHipster's setup, the applications first connect to the config server, retrieve their config which indicate the URL of the Eureka server. As this is a common config for all apps, it's set in application*.yml in config server.
