Answer 1

Seems like name is not resolving, please check if coredns is working properly. You can break down the issue like this:
from inside the pod first check you have network reachability to the internet: curl -v telnet://8.8.8.8:53
check you have connectivity to core DNS: curl -v telnet://coredns_service_name:53 or curl -v telnet://coredns_cluster_ip:53
