anyone else getting this recently? as you can see below it's ambiguous whether it's a dns lookup error or go error. i suspect it may have something to do with the dns of the motel i'm staying at, but frustratingly go get github.com/Unknwon/bra on my laptop host works fine, but running from docker (using same dns server) seems to fail, even when i add it to /etc/hosts.

cause it would get hung up on all those dns'es.

however it would always find something new to complain about.

now tried to override the docker daemon dns:

 cat /etc/systemd/system/docker.service.d/override.conf

resulting in

thinking my motel wifi dns is really bad and even blocks google dns :?

[Dieterbe]

using 8.8.4.4 works fine and solves all those issues for me /shrug.

for the record, i was also getting

~/g/s/g/r/raintank-docker ❯❯❯ docker pull hopsoft/graphite-statsd                                                                                                                            ⏎

even though index.docker.io resolved fine with my local dns as well as 8.8.4.4! i changed resolv.conf to 8.8.4.4 and that made that work as well
