Actually this is happen because docker container not using the native DNS.

Fix

Go to the docker configuration file /lib/systemd/system/docker.service

append the dns variable in the ExecStart command as follows

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --dns 8.8.8.8
