If it has an invalid DNS server, such as nameserver 127.0.x.x, then the container will not be able to resolve the domain names into ip addresses, so ping google.com will fail. Second thing to check is run cat /etc/resolv.conf on the host machine. Docker has been widely adopted and is used to run and scale applications in production.
