skaffold: Private base images don't work with skaffold properly

Skaffold cannot pull from private registry. Docker daemon can. OS and docker daemon:

root@debbie:~# uname -a
Linux debbie 4.14.0-3-amd64 #1 SMP Debian 4.14.17-1 (2018-02-14) x86_64 GNU/Linux
root@debbie:~# lsb_release  -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux testing (buster)

root@debbie:~# docker -v
Docker version 17.12.1-ce, build 7390fc6
root@debbie:~# 

Skaffold:

root@debbie:~# skaffold version
v0.2.0
root@debbie:~# 

Skaffold output:

dcherniv@debbie:~REDACTED$ skaffold run

Status: Downloaded newer image for REGISTRY/REDACTED/REDACTED:latest

After the image is downloaded to local, skaffold run succeeds. Output ommited for brevity.

What gives? my docker config is in ~/.docker/config.json

Auth is base64 encoded:

        "auths": {
                "https://REGISTRY": {
                        "auth": "REDACTEDBASE64",
                        "email": "blah@nah.id"
                },
          [....]
        }

In private docker registry logs i see requests from skaffold coming in as anonymous/unauthenticated, where with docker pull i see the request having a proper username. Private registry is running on artifactory.
