`本案例是,config向eureka注册服务.eureka和config服务器常规配置和服务器部署就不在这里说了. 这里只讲docker部署eureka和config`

#### 问题 ####

常规配置下,eureka上注册的config服务器IP为172.0.0.3,该IP为docker内部虚拟网卡的IP,外网是无法访问docker容器内IP.

#### 解决方法 ####

在config的application配置文件中增加:`eureka.instance.ip-address`  
配置文件源码如下

eureka:
        instance:
            status-page-url-path: ${
        management.context-path}/info
            health-check-url-path: ${
        management.context-path}/health
            # 指定该Eureka实例的主机名
            hostname: ${
        eureka-server-host}
            metadata-map:
                user.name: ${
        security.user.name}
                user.password: ${
        security.user.password}
                management.context-path: ${
        management.context-path}
            # 注册IP
            prefer-ip-address: true
            # 指定容器宿主机IP,非docker部署可忽略
            # 如果不指定IP,eureka则会访问docker容器IP,172.0.0.X,该IP无法访问
            ip-address: 10.10.14.240
        client:
            service-url:
                defaultZone: http://${
        eureka-server-host}/eureka

docker-compose.yml

version: '2'
    services:
        eureka:
            build: /data/docker/platform/eureka
            container_name: "platform-eureka"
            ports:
                - "20100:20100"
        config:
            build: /data/docker/platform/config
            container_name: "platform-config"
            ports: 
                - "20200:20200"
            depends_on:
                - "eureka"

效果如下  
eureka
