与尤里卡服务器和docker的spring启动应用程序
嘿，我试图运行2春季启动aps（尤里卡服务器和尤里卡客户端）和1 postgresql数据库在本地机器上的单独docker集装箱，我正面临与尤里卡客户端的一些问题。
如果我在docker集装箱外运行它们，一切工作正常。
尤里卡服务器application.yml：
server: port: 8070 eureka: instance: hostname: localhost # prefer-ip-address: false client: registerWithEureka: false fetchRegistry: false serviceUrl: defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/ security: basic: enabled: true user: name: admin password: admin 尤里卡服务器Dockerfile：
FROM java:8 EXPOSE 8070 VOLUME /tmp ADD service-registry-0.0.1-SNAPSHOT.jar app.jar RUN sh -c 'touch /app.jar' ENV JAVA_OPTS="" ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
尤里卡服务器docker运行：
docker run --rm -P --name xxx-service-registry -e "SPRING_PROFILES_ACTIVE=dev" -p 8070:8070 xxx/service-registry
尤里卡客户端application.yml：
server: port: 8020 spring: application: name: eureka-client profiles: active: dev eureka: enabled: true # instance: # leaseRenewalIntervalInSeconds: 1 # leaseExpirationDurationInSeconds: 2 client: registerWithEureka: true fetchRegistry: true serviceUrl: defaultZone: http://admin:admin@xxx-service-registry/eureka/ # lease: # duration: 5 spring: datasource: platform: POSTGRESQL url: jdbc:postgresql://xxx-database/yyy username: yyy password: yyy ribbon: eureka: enabled: true
尤里卡客户端Dockerfile：
FROM java:8 EXPOSE 8020 VOLUME /tmp ADD eureka-client-0.0.1-SNAPSHOT.jar app.jar RUN sh -c 'touch /app.jar' ENV JAVA_OPTS="" ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
尤里卡客户docker运行：
docker run --rm -P --name xxx-eureka-client --link xxx-service-registry --link xxx-database -e "SPRING_PROFILES_ACTIVE=dev" -p 8020:8020 xxx/eureka-client
所以我的尤里卡服务器启动，我可以从我的本地机器访问http：// localhost：8070 / eureka /我的数据库也开始，我也可以访问它。 我的尤里卡客户端正在启动，连接到数据库工作正常（与xxx数据库连接docker），但与尤里卡服务器连接失败，与此：

任何想法 ？ 谢谢 ！
尝试给你的微型服务这样的默认区域
eureka: enabled: true # instance: # leaseRenewalIntervalInSeconds: 1 # leaseExpirationDurationInSeconds: 2 client: registerWithEureka: true fetchRegistry: true serviceUrl: defaultZone: http://admin:admin@xxx-service-registry:8070/eureka/ # lease: # duration: 5
您可能忽略了提供服务中的端口。
