I have an external configuration repository on git containing all my propertie files.
My eureka client is microservice-order with this application file :
spring.application.name=microservice-order
spring.config.import=configserver:http://localhost:9101
This application file point to "microservice-order" propertie files :
server.port=9001
spring.data.mongodb.uri=mongodb+srv://admin:************#cluster0.yqhwqrj.mongodb.net/Facebouffe?retryWrites=true&w=majority
#configurations
configs.setOrderLimit= 5
#eureka
spring.application.name = microservice-order
eureka.client.serviceUrl.defaultZone: http://localhost:9102/eureka/
My eureka server has this propertie file :
spring.application.name=eureka-server spring.config.import=configserver:http://localhost:9101
pointing to exteral repo file "eureka-server.properties":
`
server.port= 9102
eureka.client.serviceUrl.defaultZone = http://localhost:9102/eureka/
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
spring.cloud.config.import-check.enabled=false`
I wrote "#EnableEurekaServer" (eureka-service-discovery) for server class and "#EnableEurekaClient" for client class (microservice-order)
When i start configserver, its running on 9101 port
When i start eureka-service-discovery, its running on 9102 port
When i start microservice-order, its running on 9001 port
So, each class load its own propertie files, but when i connect to http://localhost:9102/ , there is no service registered.
Do you have any idea ?
thank you !
I'm trying to register an eureka client to eureka server with external propertie files repository on github.

I am using Windows command to run my spring-boot application with emblemed tomcat. Beside, I need to run many console application using CommandlineRunner. Off cource I am facing port in use issue.
***************************
APPLICATION FAILED TO START
***************************
Description:
Web server failed to start. Port 8080 was already in use.
Action:
Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.
I can set port in every console application but I need to run at least 10 console application at the same time.
Do I have any config or solution for application auto-change port?
You can auto generate port number to get rid from Port was already in use. just put server.port= 0 in properties or yml. It is auto generate server port in console.
application.properties
server.port= 0
application.yml
server:
port : 0
console
The config server is up and the client is able to fetch the properties from config server.
HTTP GET http://localhost:8888/account-service/dev/config
Accept=[application/json, application/*+json]
Response 200 OK
But the problem is, client service is trying to start on config server port 8888. I have set server.port=8080 in the client but still not working.

Am I missing any configuration here? Highly appreciate any help.
Config server application.properties,
spring.application.name=config-server
spring.cloud.config.profiles=dev
spring.cloud.config.server.git.uri=REPO_URL
server.port=8888
Finally, I was able to find the solution. When I was trying to start client service, server.port was also getting overridden with config server port. I added server.port=8080 in the properties file for the client service profile in config repo (account-service.properties) and it worked.
I've created a new spring boot project with "spring-cloud-starter-netflix-eureka-server" dependency. Also have added "#EnableEurekaServer" annotation and launched the spring boot app.
I see the below log messages
o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8080 (http)
c.n.eureka.cluster.PeerEurekaNodes : Adding new peer nodes [http://localhost:8761/eureka/]
From above, as I understand. Tomcat is running on port 8080 and eureka server is running on port 8761.
If so,
How come the Eureka Dash board is accessible at http://localhost:8080/ ? When the eureka server is running on port 8761 ?
On one of the client, I configured the following in the .properties file
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
Above, I specified the Eureka server location. But, why is the client unable to register?
Thanks!
By default it works on 8761, so configure server.port=8761
Eureka-server(MediaStoreEurekaServer): bootstrap.properties
spring.application.name=MediaStoreEurekaServer
server.port=9091
eureka.client.serviceUrl.defaultZone=http://localhost:9091/eureka}
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
Eureka-client(Config-Server): bootstrap.properties
spring.application.name=Config-Server
server.port=9093
user.home=${HOME}
spring.cloud.config.server.native.search-locations=file://${user.home}/IdeaProjects/MediaStore/centralProperties
spring.profiles.active=native
eureka.client.serviceUrl.defaultZone=http://localhost:9091/eureka
With above 2 properties (services running on same machine), Config-Server is able to register with MediaStoreEurekaServer eureka registry server when using http://localhost:9091/eureka.
I don't want to use localhost. When I use http://MediaStoreEurekaServer:9091/eureka , Config-Server is not able to register.
Can we use something other than localhost for eureka client to find the eureka server like service or instance name? when services are running on same host
Edit 1:
This is what eureka client spring logs give when in eureka client properties file i set
eureka.client.serviceUrl.defaultZone=http://MediaStoreEurekaServer:9091/eureka
Error:

I have Eureka server, Eureka zuul and config server.
So I write a simple microservice. Then, running on 8686 port.
So I want to run that microservice on another port.
I trying that command. But don't work.
java -Dserver.port=8687 -jar -Dlogging.file="bla.log" testMicro.jar --debug > "bla.log"&
I am confusing. Help me!
You have two ways to running your instances on different ports.
user assignment of random port from a specified range:
server:
port: ${random.int(8080,8090)}
Set in property file from config server for testMicro microservice the following configurations:
spring:
cloud:
config:
override-system-properties: false
allow-override: true
override-none: true
and then run again your jar with -Dserver.port=8687 property
