docker - 无法从另一个容器“错误地址”ping 容器

Question

我有一些容器的堆栈。其他人无法通过他的主机名访问其中一个，这似乎是一个 IP 地址问题。

码头工人网络检查我的堆栈

        ]

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（错误地址错误），但它适用于我的服务的 ip 地址：

/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'

docker网络有问题，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 ！
