How to deal with docker deployed spring cloud application mutual access through zuul？ - spring-boot

Question

I deployed my spring cloud application in docker,include eureka server,zuul,eureka client. I want to access eureka client via zuul.
Zuul and eureka client are registered at eureka server.I access each application ,it is work. When I access eureka client via zuul, zuul console infomation show java.net.NoRouteToHostException. I don't know why and how to deal with this problem.

My test operate is like this.
I access the zuul by http://192.168.90.183:8088 ,it works well.
I access the eureka client by http://192.168.90.183:8926/getCityCenter , it works well.
When I access the eureka client via zuul by
http://192.168.90.183:8088/371300/getCityCenter , it doesn't work.
The console show the information like this.

It seems the zuul can't find the router to eureka client of tdcm.
I tried to deployed all application on computer,include eureka server,zuul,eureka client,not in docker. The same config as this article descript,it works well. I don't know why it isn't work when access the eureka client via zuul in docker deployed.
I use the host computer IP address for spring cloud appliction.
My docker version is 17.12.1-ce.
My spring cloud version is Finchley.SR1.
My Spring boot version is 2.0.3.RELEASE.
My host computer is cent-os 7.
How can I deal with the problem?

Answer 1

I know the problem how to dealing.Eureka client config delete the yml value of ip-address.
eureka:
instance:
ip-address: 192.168.90.183
The reason is eureka client config in the inner network of docker.It can access from zuul through inner network of docker.
