无法解析码头集装箱之间的主机名

我有两个在独立的合成文件中创建的容器（为应用程序隔离完成 - 每个应用程序可能在合成文件中定义了多个容器，如后备数据库）。无法解析码头集装箱之间的主机名

这些容器通过名为“common”的外部网络进行链接。

一个例子撰写文件将是：

version: '2' 

services: 

    rabbitmq: 
    image: "rabbitmq:3-management" 
    hostname: "rabbitmq" 
    container_name: "rabbitmq" 
    environment: 
     RABBITMQ_ERLANG_COOKIE: "SWQOKODSQALRPCLNMEQG" 
     RABBITMQ_DEFAULT_USER: "rabbitmq" 
     RABBITMQ_DEFAULT_PASS: "rabbitmq" 
     RABBITMQ_DEFAULT_VHOST: "/" 
    ports: 
     - "15672:15672" 
     - "5672:5672" 

networks: 
    default: 
    external: 
     name: common

泊坞版本：

常见的网络使用创建：

docker network create common

然后，我把集装箱起来使用：

docker-compose up -d

检查网络我得到：

[email protected]:~# docker network inspect b5e8f81a8ea0

    { 
     "Name": "common", 
     "Id": "b5e8f81a8ea063149298d2023be5740c8d971e0329a741abdafbac59fd882684",

     "Driver": "bridge", 
     "EnableIPv6": false, 
     "IPAM": { 
      "Driver": "default", 
      "Options": {}, 
      "Config": [ 
       { 
        "Subnet": "192.168.0.0/16" 
       } 
      ] 
     }, 
     "Internal": false, 
     "Containers": { 
      "6137864e71161b417f0659b88b3e17538fb60277ca818e58b255d5cc17932c3c": {

       "MacAddress": "02:42:c0:a8:00:03", 
       "IPv4Address": "192.168.0.3/16", 
       "IPv6Address": "" 
      }, 
      "61b1288bf250196d02f3933c8bbde732fbcd24bdf3949c4f53b3b05aa87f3c7f": {

       "MacAddress": "02:42:c0:a8:00:02", 
       "IPv4Address": "192.168.0.2/16", 
       "IPv6Address": "" 
      } 
     }, 
     "Options": {}, 
     "Labels": {} 
    } 
]

其他容器已经崩溃，因为他们无法解决的“RabbitMQ的”主机名。检查坠毁的容器表明它们是在同一网络上：

[email protected]:~# docker inspect bae5214bf619 
"NetworkSettings": { 
    "Bridge": "", 
    "SandboxID": "54a8b0833204522a75cf2e4195c5838b336ab82438aa53d9f1f38276eb9f6061",

    "IPv6Gateway": "", 
    "MacAddress": "",

     "common": { 
      "IPAMConfig": null, 
      "Links": [ 
       "db" 
      ], 
      "Aliases": [ 
       "rulesengine", 
       "bae5214bf619" 
      ], 
      "NetworkID": "b5e8f81a8ea063149298d2023be5740c8d971e0329a741abdafbac59fd882684", 
      "EndpointID": "", 
      "Gateway": "", 
      "IPAddress": "", 
      "IPPrefixLen": 0, 
      "IPv6Gateway": "", 
      "GlobalIPv6Address": "", 
      "GlobalIPv6PrefixLen": 0, 
      "MacAddress": "" 
     } 
    } 
}

如果我登录到没有试图访问RabbitMQ的容器，并没有崩溃的容器中，主机名不解析。但是，rabbitmq容器的ip地址是可达的。

[email protected]:~/David.Deployments# docker exec -it 6137864e7116 bash 
[email protected]:/# ping rabbitmq 
ping: unknown host 
[email protected]:/# ping 192.168.0.2

64 bytes from 192.168.0.2: icmp_seq=1 ttl=64 time=0.043 ms

当签订到RabbitMQ的容器：

[email protected]:/# docker exec -it rabbitmq bash 
[email protected]:/# uname -n 
rabbitmq 
[email protected]:/# ip a 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1

是否有我怎么能解决这个问题或事情我应该检查什么建议？
