Docker-Spring Cloud Config Client，与Config Server发现一起发布

Question

我正在试用Spring Cloud Netflix stack和Spring Cloud Config服务器和客户端。

version: '3'
services:

#Eureka Service
  discovery:
    container_name: discovery
    image: jbprek/discovery:latest
    ports:
      - "8761:8761"

#Spring cloud config server
  configservice:
    container_name: configserver
    image: jbprek/configserver:latest
    ports:
      - "8888:8888"
    depends_on:
      - discovery

#Example microservice using discovery and spring cloud config
  constants-service:
    container_name: constants-service
    ports:
      - "8080:8080"
    image: jbprek/constants-service:latest
    depends_on:
      - discovery
      - configservice

git clone https://[e-mail]/prek/boot-netflix-problem.git

spring.application.name=constants-service
spring.cloud.config.uri=http://configserver:8888

然后，为了通过发现查找configserver，然后从constant-service检索配置，我修改了bootstrap.properties文件，如下所示：

spring.application.name=constants-service
#Lookup through Eureka
spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.service-id=CONFIGSERVER

通过使用localhost而不是discovery作为eureka主机名，上述更改具有阻止“constants-service”连接到eureka的效果，并且configserver服务的查找和向eureka的自我注册都将失败。

用于发现的Application.Properties为：

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

server.port=8888
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://discovery:8761/eureka

spring.cloud.config.server.git.uri=https://bitbucket.org/prek/boot-netflix-problem-config-data.git
spring.cloud.config.server.git.clone-on-start=true
spring.cloud.config.server.git.force-pull=true
spring.cloud.config.discovery.enabled=false

spring.application.name=constants-service

eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://discovery:8761/eureka

spring.application.name=constants-service

eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://discovery:8761/eureka

spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.service-id=CONFIGSERVER

Answer 1

您正在将应用程序切换到“发现优先模式”，因此您的常量服务应该了解Eureka并通过名称从其获取configserver URL。

问题很简单：constants-service的bootstrap.properties不包含到Eureka的URL，您应该将Eureka客户端配置从git repo（application.properties）移到bootstrap.properties。
