Docker DNS Resolution on Private Networks

Docker DNS Resolution on Private Networks: a task in Terminal-Lego-15k (Harbor dataset). When Docker containers are running on a host that uses a local DNS resolver (like dnsmasq or systemd-resolved ) with nameserver 127.0.1.1 or nameserver 127.0.0.53 in /etc/resolv.conf , Docker cannot use that…
