Docker Host ping Different Container Networks

  docker, question

My host computer is mac, container system is centos7, nginx is installed in it, and it is running.

The following is information about the inspect network of my docker container. My interface is0.0.0.0:32768->80/tcp

"Networks": {
 "bridge": {
 "EndpointID": "3baeeaabe81b5d3b38ef9db487843e93727a1ae00718bb912d574e947a7cb308",
 "Gateway": "172.17.0.1",
 "IPAddress": "172.17.0.3",
 "IPPrefixLen": 16,
 "IPv6Gateway": "",
 "GlobalIPv6Address": "",
 "GlobalIPv6PrefixLen": 0,
 "MacAddress": "02:42:ac:11:00:03"
 }
 }

However, I cannot ping 172.17.0.3 at the host computer and cannot open 127.0.0.1:32768

https://docs.docker.com/docke …This article clearly states that it is impossible to ping containers under mac due to system restrictions.
