Lost hostname resolution on Ubuntu Docker 16.04
I don’t know what happened.. I lost DNS resolution on my Ubuntu Docker 16.04 DO droplet.
root@gpc-docker-sfo2:resolvconf$ telnet gitlab.com 443
telnet: could not resolve gitlab.com/443: Temporary failure in name resolution
root@gpc-docker-sfo2:resolvconf$ cat /etc/resolv.conf
I don’t know what happened? How do I get this back working?
(Ubuntu Docker 1.12.5 on 16.04)
As a note: I’ve always kept my apps updated via apt-get. Was there something related to the recent Docker 13.0 update?
