Unable to access local network IP from docker container

Question

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 machin

Answer 1

I tried the following, and it works:

mac-os $> ifconfig
en0: flags=8863 mtu 1500
    ether 78:31:c1:bd:4b:84 
    inet6 fe80::1425:a90d:9c00:ef53%en0 prefixlen 64 secured scopeid 0x4 
    inet 10.191.41.1 netmask 0xfffff800 broadcast 10.191.47.255
    nd6 options=201
    media: autoselect
    status: active

So my ip is 10.191.41.1. Then I do:

mac-os $> docker run -ti --rm ubuntu bash -c "apt-get update && apt-get install -y inetutils-ping && ping 10.191.41.1"

Which installs the "ping" command, and tries to ping my host. I get the right answers:
