golang, kubernetes dns

gistfile1.txt

the problem: 
a golang binary inside a container inside a vm on osx can't resolve a hostname:

```
dial tcp: lookup "…": no such host
```

switching to the cgo resolver via GODEBUG=netdns=cgo results in the same problem.

the hostname can be found on the VM, confirmed via `dig`
the hostname can be found inside the container, confirmed via `dig`
only the running go-binary can't resolve the hostname

running the container directly results in a working binary.

ideas?
