rancher上config不能正常注册eureka集群

Question

师兄，下午好！

如下问题已经折腾我一天了，还是未能解决，急盼师兄指点下！
你的对应章节代码和配置文件，我都比较了，基本一致，版本也是一致的。
(最开始我是完全按照你视频的做法来操作的，还是不行，针对网上介绍的办法 ，如下有些配置文件做了少量修改，还是仍未能解决)
－－－－－－－－－－－－－－－－－－－－－－－－
我本地
相关运行环境说明如下
rancher-server 192.168.16.35
rancer-agent 192.168.16.42
－－－－－－－－－－－－－－－－－－－－－－－－－－－
我本地hosts文件如做了eureka1和eureka2的主机名映射如下
192.168.16.42 eureka1 eureka2
－－－－－－－－－－－－－－－－－－－－－－－－－－－
applicaiont-eureka1.yml文件内容如下
eureka:
client:
service-url:
defaultZone: http://eureka2:8762/eureka/
# register-with-eureka: false
server:
enable-self-preservation: false
instance:
# prefer-ip-address: false
hostname: eureka1
spring:
application:
name: eureka
server:
port: 8761
－－－－－－－－－－－－－－－－－－－－－－－－－－－
applicaiont-eureka2.yml文件内容如下
eureka:
client:
service-url:
defaultZone: http://eureka1:8761/eureka/
# register-with-eureka: false
server:
enable-self-preservation: false
instance:
prefer-ip-address: false
hostname: eureka2
spring:
application:
name: eureka
server:
port: 8762
－－－－－－－－－－－－－－－－－－－－－－－－－－－
config工程对应的 application.yml文件内容如下
eureka:
client:
service-url:
defualtZone: http://eureka1:8761/eureka/,http://eureka2:8762/eureka/

spring:
application:
name: config
cloud:
config:
server:
git:
uri: https://gitee.com/heyitang123/config-repo.git
username: 18617xxxxxx
password: xxxxxx
basedir: /home/yml/
force-pull: true

management:
endpoints:
web:
exposure:
include: “*”
－－－－－－－－－－－－－－－－－－－－－－－－－－－
其它配置及代码与示例代码基本相同
－－－－－－－－－－－－－－－－－－－－－－－－－－－
********************************
现在出现的问题如下
********************************
不发布到rancher中，就在本地通过docker运行，eureka1和eureka2能够相互注册，相互复制，config能正常注册到eurek1和eureka2中
通过 http://eureka1:8761 和 http://eureka2:8762, 访问一切正常。

如上代码通过bash build.sh 推送到阿里云后，再通过rancher-server，安装eureka1,eureka2,config 服务后，ureka1和eureka2能够相互注册，相互复制，但是config始终不能正常注册到eurek1和eureka2中
通过 http://192.168.16.42:8761 , http://192.168.16.42:8762,http://eureka1:8761, http://eureka2:8762 都能正常看到 ureka1和eureka2能够相互注册，相互复制，但就是看不到 config注册上去, 通过config工程的端口能够正常访问到 gitee中的配置文件。

注册不上去，基本上可以确定是网络问题。

defualtZone: http://eureka1:8761/eureka/,http://eureka2:8762/eureka/

你可以在config所在的docker容器里，ping一下eureka1

你的rancher搭建在外网服务器吗？在外网可以发出来，我登录进去看看

• 提问者 网络时空 #1

  师兄好，我目前的 rancher是搭建我本地虚拟机中。
  
  网络问题，我觉得可以排除，因为，我在config进入命令行后，进行如下操作均是通的 
  ping eureka1 和 telnet eureka1
  ping eureka2 和 telnet eureka2

• 提问者 网络时空 #2

  非常感谢！

• 廖师兄 回复 提问者 网络时空 #3

  从错误日志上来看就是网络问题，config和eureka使用的SpringCloud版本一样吗？你把它部署在公网上，地址发出来，我去看看。

提问者 网络时空 2020-03-26 12:37:35

感谢师兄，问题终于解决了。原来是部署 config服务时，网络类型默认是 托管，它会从当前的网络段中请求一个指定的IP地址，如果此IP地址已经被使用则会分配一个随机IP，这样实际上是注册不到eureka的。要选择 网络类型为主机就马上正常了！

其实，也可以说是师兄提到的网络问题！感谢了！

正常图示如下，折腾了我两天的问题终于解决了！

师兄好，我目前的 rancher是搭建我本地虚拟机中。

网络问题，我觉得可以排除，因为，我在config进入命令行后，进行如下操作均是通的
ping eureka1 和 telnet eureka1
ping eureka2 和 telnet eureka2

我感觉是不是哪里要做什么配置？ 比如说只能通过域名访问，不能通过主机名访问？

提问者 网络时空 2020-03-25 18:19:17

config在 rancher的错误日志部分主要信息如下，大概意思好象是找不到eureka服务器,针对如下信息，我在网上也搜索了下，使用各种方法，还是未能解决这个问题，真是郁闷了！
