My application Is running on port 8444 but I want my actuator metrics to be exposed to a different port, by default I can access them via https://localhost:8444/actuator/health but I want them on a different port like 8086
https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-customizing-management-server-port
I followed this document and added management.server.port=8086 in my application.yml but it's just showing that site can't be reached
I tried other properties such as changing the endpoint base-path and that seems to be working fine.
I am using Spring boot 2.2.4.RELEASE and Wildfly 18,
Here is my application.yml
server:
port: 8443
servlet:
context-path: /appName

app:
name: name

Thanks for taking the time to read my post.
My issue is as such. I have 2 microservices (auth-service and image-service) deployed on Heroku, as well as a server Eureka and a gateway Zuul.
In local, all of this works.
However, when deployed, the same calls give me 404 errors : for example :
zuul is deployed on port 8762 in local,
so http://localhost:8762/images/user/create works, it points to http://localhost:8200/user/create of the image-service.
Deployed, https://croquis-time-image.herokuapp.com/user/create works, but https://croquis-time-zuul.herokuapp.com/images/user/create throws a 404 error.
On eureka however, all my services are registered, so the trouble doesn't come from there. I thought perhaps zuul didn't manage to get all the services from Eureka, but I'm not sure how to check.

I have tried removing and adding the "ignored-services" from zuul to see if that was the problem, but it didn't change anything.
I'm very willing to edit my question with more information if you require more, I'm not sure where is the origin of the problem, so I'm a bit at a loss as to what to add.
Thanks !
you have an issue with the configuration of .yml in zuul server
Your .yml of zuul server must be:
instance:
hostName: croquis-time-zuul.herokuapp.com
And your .yml of image must be:
instance:
hostName: croquis-time-image.herokuapp.com
because instance.hostname is the host of your application acting as the eureka client. if you need more information please visit: https://blog.heroku.com/managing_your_microservices_on_heroku_with_netflix_s_eureka
I am trying to run an example with zuul and Eureka server.
Below are my configurations:
eureka-service
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
logging.level.com.netflix.eureka=OFF
logging.level.com.netflix.discovery=OFF
eureka -client (bootstrap.properties):
spring.application.name=ab
management.server.port=9001
management.server.address: 127.0.0.1
server.port=8081
edge-service(zuul) :
zuul.routes.ab.url=http://localhost:8081
ribbon.eureka.enabled=false
spring.application.name=API-Gateway
eureka.client.eureka-server-port=8761
server.port=8080
While I am hitting the URL http:localhost:8080/clientapi, I get a white label error page, what configuration seems to be missing, as I could see edge-service, as well as eureka-client, registered correctly with the eureka -server.
I am using spring boot: 2.1.4.
Let me show you my example:
eureka in application.yml file:
server:
port: 8761
eureka:
client:
register-with-eureka: false
fetch-registry: true
instance-info-replication-interval-seconds: 10
server:
eviction-interval-timer-in-ms: 50000
wait-time-in-ms-when-sync-empty: 5
zuul:
zuul.routes.1.url=http://localhost:8081
zuul.routes.2.url=http://localhost:8082
zuul.prefix=/client
zuul.host.max-per-route-connections=10
zuul.host.max-total-connections=10
I have 2 services (1 - localhost:8081 and 2 - localhost:8082)
You need annotate main class Zuul:
#EnableZuulProxy
#EnableDiscoveryClient
Then start application. When you go to
localhost/8070/client/1
you will redirect to first service (localhost:8081)
When you go to
localhost/8070/client/2
I hope it will help you.
you will redirect to second service (localhost:8082)
I have a couple of microservices on Heroku - eureka-server, Zuul server and some app services.
While I am trying to reach any of my services, for example, "service1" via Zuul gateway, Zuul is unable to forward the request to the respective service (when I'm trying to run them locally everything works fine).
I've found the following errors in Zuul logs:
com.netflix.zuul.exception.ZuulException: Forwarding error
Caused by: com.netflix.client.ClientException: Load balancer does not have the available server for the client: service1
Below are configurations of my services:
1) "zuul server" application.yml
server:
port: ${PORT:8000}
zuul:
prefix: /api
ignoredServices: '*'
routes:
service1:
path: /path_for_service1/**
serviceId: service1
strip-prefix: false
...
management:
endpoints:
web:
exposure:
include: "*"
eureka:
client:
serviceUrl:
defaultZone: ${EUREKA_URL:http://localhost:5000}/eureka/
2) "eureka server" application.yml
server:
port: ${PORT:5000}
eureka:
instance:
hostname: localhost
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
3.1) "service1" application.yml
server.port=${PORT:8081}
eureka.client.service-url.defaultZone=${EUREKA_URL:http://localhost:5000}/eureka/
3.2) "service1" bootstrap.yml
spring:
application:
name: service1
All microservices are visible in eureka dashboard.
If I change zuul routes to hard-coded url it works well but it is not what I'm looking for.
zuul:
prefix: /api
ignoredServices: '*'
routes:
service1:
path: /path_for_service1/**
url: http://url_of_service_1
strip-prefix: false
Could you please help me with this issue?
Finally, I've found root cause :)
All services are registered in eureka using heroku hostname by default (like "085930c7-b893-4b34-88a7-6e37fbe7fa0f") which is not accessible outside.
But services are accessible by domain names.
So I just added domain name settings to application.properties of each service (https://blog.heroku.com/managing_your_microservices_on_heroku_with_netflix_s_eureka)
eureka:
instance:
non-secure-port: 80
hostname: ${DOMAIN_NAME}
and now it works.
Is there anyway to make spring cloud config client's application.yml read values from spring config server?
For example,
on my spring cloud config client, the application.yml is like this
spring:
application:
name: clienttest
mvc:
view:
prefix: /jsp/
suffix: .jsp
server:
port: 8080
context-path: /clienttest
tomcat:
uri-encoding: UTF-8
eureka:
client:
service-url: {"defaultZone":"http://dev.euraka01.app.com:8769/eureka/,http://dev.euraka02.app.com:8770/eureka/"}
instance:
prefer-ip-address: true
and my bootstrap.yml file is as below
spring:
application:
name: clienttest
cloud:
config:
name: clienttest
uri: http://192.168.2.101:9000
enabled: true
profile: out_test
label: master
now for the service-url value, for different environment, I have to config different eureka url values, my question is that, is there anyway that I can config the service-url value in the config server? like I set the value as ${service-url} in the application.yml, and when I start the config client server, it get the value from the config server according the profile and label which I set in the bootstrap.yml.
You can look up properties on the config server by both profile and label, where label is either either a branch, tag.
/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
In your example above your config server will try and find a file named
clienttest-out_test.properties
In the git repo on the master branch.
spring:
application:
name: clienttest
cloud:
config:
profile: out_test
label: master
See the example and also a good doc here
Essex Boy,
Thank you very much for your help, and I was able to read the value from different config profile before.
My question is how to make application.yml get the value from config server, and now I've solve it by myself, the answer is quite easy, in the application, set value like ${service-url}, the full answer is as below:
in my application.yml, the content is as below:
spring:
application:
name: clienttest
server:
port: 8080
context-path: /clienttest
tomcat:
uri-encoding: UTF-8
eureka:
client:
service-url: {"defaultZone":"${service-url}"}
instance:
prefer-ip-address: true
Please note the service-url value, now the value is set as {"defaultZone":"${service-url}"}, and in my application.properties file which on the config server, the properties file content is as below:
service-url=http://192.168.2.101:8769/eureka/,http://192.168.2.101:8770/eureka/
then when I start the mocroservice, it could resist it self on the http://192.168.2.101:8769/eureka/ and http://192.168.2.101:8770/eureka/
which is what result I want.
I have Eureka setup with my spring boot application, and Eureka has a neat web UI built in which I like
Here's my config in application.yml
server:
port: 8081
management:
context_path: /admin
## EUREKA CONFIG ##
eureka:
instance:
hostname: localhost
metadataMap:
instanceId: ${spring.application.name}:${spring.application.instance_id:${random.value}}
client:
registerWithEureka: true
fetchRegistry: true
server:
waitTimeInMsWhenSyncEmpty: 0
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
However, the web UI shows up on my eureka server at
http://localhost:8081/
is there a way to change the url of the web ui only to something like
http://localhost:8081/eurekawebui
Thanks
You can set eureka.dashboard.path=/eurekawebui. It defaults to /.
