Question

我堆满了一些容器。主机名无法访问其中一个，这似乎是ip地址问题。

docker网络检查mystack

            {
                "Name": "1b4f79e8e881",
                "IP": "192.168.1.67"
            }
        ]

api服务可以使用主机名ping webview服务，但这不是我的webview服务的好IP：

# ping webview
PING webview (10.0.2.17) 56(84) bytes of data. // NOT THE GOOD IP ! (it should be 10.0.2.32)
64 bytes from 10.0.2.17 (10.0.2.17): icmp_seq=1 ttl=64 time=0.126 ms 
64 bytes from 10.0.2.17 (10.0.2.17): icmp_seq=2 ttl=64 time=0.099 ms

webview无法使用主机名ping API服务（错误的地址错误），但可以与我的服务的ip地址一起使用：

/app # ping 10.0.2.35
PING 10.0.2.35 (10.0.2.35): 56 data bytes
64 bytes from 10.0.2.35: seq=0 ttl=64 time=0.331 ms
64 bytes from 10.0.2.35: seq=1 ttl=64 time=0.140 ms
^C
--- 10.0.2.35 ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.140/0.235/0.331 ms
/app # ping api
ping: bad address 'api'

泊坞窗网络存在问题，但我不知道如何解决。我已经卸载并重新安装了docker，删除了docker eth条目...知道吗？非常感谢您的帮助！

可能是关于图片版本的错误，如果再次出现此错误，在删除所有图像之前尝试以下行：

apt-get update

apt-get install iputils-ping

无法从另一个容器“错误地址” ping容器
