Tried this with Fedora 24 and very similar config (but centos7 image) and I'm able to ping localhost.
$ cat /etc/hosts # Kubernetes-managed hosts file. 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet fe00::0 ip6-mcastprefix fe00::1 ip6-allnodes fe00::2 ip6-allrouters 172.17.0.2 centoscentos7-debug I have net.ipv6.conf.all.disable_ipv6 = 1 set - should be possible. Can you provide your /etc/resolv.conf from inside that image?
