Register with name rather than IP #78

Hi, is there a way to have a python client register with the Java Eureka registry using the instance name? The java/spring services list in the registry with a name and are accessible, but the python ones using this library display with the IP and I then get an error via the gateway when trying to access. - Failed to resolve 'testservice-cf78478d5-brx52' [A(1)] after 2 queries. Either that or I am missing some configuration somewhere and need to have both java and python services in the stack. any help appreciated. thanks!

Do you set app_name in the init method?

mng77 commented 1 year ago

Yes,

eureka_client.init( eureka_server=self.server_url, app_name=self.app_name, instance_port=instance_port, renewal_interval_in_secs=10 )

What I see on the eureka page for a java service e.g gateway is gateway-f4d6dd9f7-4z6nl:gateway:8760, but for a python app this shows as [10.11.12.13:testservice:50999] and python services don't seem to be dynamically discovered through the gateway, only way I got it to work was if I specify the actual route in the gateway. am I possibly missing some options somewhere? thanks

You may set instance_host, this component now will not find the hostname automatically. And where is your component run at? In a docker environment or K8S?

mng77 commented 1 year ago

I set instance_host=socket.gethostname() but that didn't make a difference. Im deploying out to openshift so K8s. A new java tool can be successfully deployed and registers/accesses correctly by pointing at the registry host e.g http://registry.server.name:8761/eureka, using that same line in the python client for eureka server though leads to a 503 error as it cannot connect. its all in the same area as well
