无法从Docker容器访问本地网络IP [英] Unable to access local network IP from docker container

问题描述

在其上运行macOS和docker ubuntu，我无法对本地网络的IP地址执行ping操作.以下是我的docker容器的网络配置.我可以ping通主机的IP地址，但是无法访问本地网络上的其他IP地址.

Running macOS and docker ubuntu on it, I am unable to ping my local network's IP addresses. Below is the network configuration of my docker container. I can ping my host machine's IP address but I am unable to access other IP addresses on the local network.

root# ping 172.17.101.192
PING 172.17.101.192 (172.17.101.192) 56(84) bytes of data.
From 172.17.0.3 icmp_seq=1 Destination Host Unreachable
From 172.17.0.3 icmp_seq=2 Destination Host Unreachable

root# ifconfig         
eth0      Link encap:Ethernet  HWaddr 02:42:ac:11:00:03
          inet addr:172.17.0.3  Bcast:0.0.0.0  Mask:255.255.0.0
          inet6 addr: fe80::42:acff:fe11:3/64 Scope:Link

是否有任何网络配置可以帮助我执行此操作?

Is there any network configuration which would help me to perform this operation?

我已经尝试过net=host，但是它没有帮助.

I have tried net=host but it is not helping it.

推荐答案

我在Mac上使用docker，问题是docker内部网络与我的本地网络地址冲突. 要解决此问题，我需要进入dokcer菜单中的Preferences. 在偏好设置"菜单Daemon>Advanced Menu中，我可以提供其他bip.

I was using docker for mac, the issue was docker internal network conflicting with my local network addressing. To resolve the this issue, i need to go to Preferences in the dokcer menu. In Preferences menu Daemon>Advanced Menu, i can supply other bip.

{
    "bip" : "12.12.0.1/24"
}

单击应用"，然后重新启动.下次docker将以内部网络12.12.0.1/24开始.

Click apply and restart. The next time docker will start with internal network as 12.12.0.1/24.
