解决docker启动时报‘Error response from daemon: network xxx not found‘问题

绝地灬酷狼 2023-10-09 21:41 29阅读 0赞

公司近期更换了网络设备，网段也更换了，导致原来的测试服务器无法连接，网关强制重启后才得以解决。  
服务器启动后几个docker服务没有正常重启。  
执行命令查询服务状态

docker ps -a

确实有几个服务停止运行了，于是手动执行启动命令

docker start nacos

返回异常信息

Error response from daemon: network f0e06a7bb7c48bc5765c576a78fbc918062ebd18ab0c2c5f95a22109f43e4d5b not found

再次查看创建的`network`信息

docker network ls

得到的结果如下

<table> 
 <thead> 
  <tr> 
   <th>NETWORK ID</th> 
   <th>NAME</th> 
   <th>DRIVER</th> 
   <th>SCOPE</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>f329f40ed61b</td> 
   <td>bridge</td> 
   <td>bridge</td> 
   <td>local</td> 
  </tr> 
  <tr> 
   <td>23da4d14f772</td> 
   <td>host</td> 
   <td>host</td> 
   <td>local</td> 
  </tr> 
 </tbody> 
</table>

查看网络的具体配置

docker network inspect f329f40ed61b

得到的结果

                    "IPv6Address": ""
                },
                ... ... <省略其他配置>

再查看刚才的`nacos`容器详情

docker inspect nacos

得到的网络配置信息如下

... ...
    "Networks": {
        
       "network": {
        
           "IPAMConfig": {
        
               "IPv4Address": "172.16.0.4"
           },
           "Links": null,
           "Aliases": [
               "d3183ca265e9"
           ],
           "NetworkID": "f0e06a7bb7c48bc5765c576a78fbc918062ebd18ab0c2c5f95a22109f43e4d5b",
           "EndpointID": "",
           "Gateway": "",
           "IPAddress": "",
           "IPPrefixLen": 0,
           "IPv6Gateway": "",
           "GlobalIPv6Address": "",
           "GlobalIPv6PrefixLen": 0,
           "MacAddress": "",
           "DriverOpts": null
       }
    }

可以看得到两个IP不一样，那就肯定原来`nacos`所绑定的`network`被删除了，需要重新创建

docker network create --driver bridge --subnet 172.16.0.0/16 --gateway 172.16.0.1 network

查看创建后的网络信息

docker network list

可以看到已经创建好了，之后需要重新绑定

先解绑

docker network disconnect 0713e1d89b4b nacos

再绑定

docker network connect 0713e1d89b4b nacos

再次查看容器的网络信息，正常显示了

"Networks": {
        
       "network": {
        
           "IPAMConfig": {
        },
           "Links": null,
           "Aliases": [
               "d3183ca265e9"
           ],
           "NetworkID": "0713e1d89b4bb63af3c66c98448c5581ec2c5cd32573af71bff16e00fe1a1439",
           "EndpointID": "532a01a29124eed661e67ab3cc0e7c3fd772dc584adc1d944757e1be57951c46",
           "Gateway": "172.16.0.1",
           "IPAddress": "172.16.0.3",
           "IPPrefixLen": 16,
           "IPv6Gateway": "",
           "GlobalIPv6Address": "",
           "GlobalIPv6PrefixLen": 0,
           "MacAddress": "02:42:ac:10:00:03",
           "DriverOpts": {
        }
       }
    }

重新启动服务

docker start nacos

正常启动，剩下的网络也按照这个方法启动成功。
