When I tried to build a test server on docker for web application development, it failed.

It's easy to see that the name of registry.yarnpkg.com cannot be resolved. But why? You can do nslookup from the command line normally? If you think that, there seems to be a problem with the DNS on the VirtualBox side. It is sandwiched between the OS and the container to prepare the Linux kernel, and it is surprisingly easy to overlook the problem. When you hit it on VirtualBox,
dcoker@default:~$ nslookup registry.yarnpkg.com
Server: 10.0.2.3
Address 1: 10.0.2.3
nslookup: can't resolve 'registry.yarnpkg.com'
Quickly add 8.8.8.8 to the secondary to the DNS server.
dcoker@default:~$ sudo -i
root@default:~# vi /etc/resolv.conf
DNS settings [resolv.conf] Disable overwriting after reboot
/etc/resolv.conf
nameserver 10.0.2.3
+ nameserver 8.8.8.8
8.8.8.8 is the address of Google Public DNS, which is a reliable ally when you have trouble with DNS.
Due to the difference in keyboard layout, the colon : cannot be typed and vi cannot be terminated! If you are such a JIS array user, press '+' (Shift +';').

Note that this is a first aid measure and will not be a permanent solution, such as restarting VirtualBox.
