J'exécute mon serveur eureka sur mon hôte local. Je peux enregistrer tous mes autres sur les services en cours d'exécution localhost et tout fonctionne comme prévu.
Maintenant, je veux enregistrer un service qui s'exécute sur une machine Linux. Mes propriétés ressemblent à ça:
spring.application.name=myService-service
spring.cloud.config.uri=http://myMachine.domain.lan:8888
server.port=8002
eureka.client.service-url.default-zone=http://myMachine.domain.lan:8761/eureka/
Mais le service ne peut pas s'enregistrer sur le serveur eureka sur localhost. (À la fin c'est le même service qui fonctionne sur localhost)
Je reçois ces exceptions:
Java.net.ConnectException: Connection refused
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
Mais je peux obtenir mes fichiers de configuration à partir de mon service de configuration s'exécutant sur localhost.
Quelles sont les configurations nécessaires pour enregistrer mon service sur eureka de la machine linux (client) à localhost (serveur)?
J'utilise ces annotations:
Un service:
@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class MyServiceApplication {
Serveur Eureka:
@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {
P.S.: De même, la méthode opposée ne fonctionne pas. Cela signifie avoir eureka server sur la machine linux et les services sur localhost. Obtenez les mêmes exceptions.
Edit1:
Propriétés d'Eureka-Server:

testsrv est la machine linux. (172.25.82.108)

Après avoir remplacé .properties
par le fichier .yml
de l'un de mes services et corrigé l'orthographe de defaultZone
, tout fonctionne comme prévu.
