Solve

reason

default DNS server can not resolve domain name to IP.
default DNS file: /etc/resolv.conf

root@song-Virtual-Machine:/etc# cat /etc/resolv.conf 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search corp.microsoft.com

get actual DNS server

Get/Set DNS server

$ cat /etc/resolv.conf | grep nameserver  # What Docker sees
nameserver 127.0.1.1
$ nmcli dev show | grep IP4.DNS  # My actual DNS server
IP4.DNS[1]:                             10.50.50.50

Fail Info

song@song-Virtual-Machine:~/git/apps/nginx$ docker run busybox nslookup corp.microsoft.com
Server:    8.8.8.8
Address 1: 8.8.8.8

nslookup: can't resolve 'corp.microsoft.com'

Edit resolve.conf with actual dns server

root@song-Virtual-Machine:/etc# cat /etc/resolv.conf 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
#nameserver 127.0.1.1
nameserver 10.50.50.50
