Empty output from "reg tags" in GCR

[ahmetb]

I am using GCR.io and authenticated to the engine with gcloud docker -a (provides short-lived tokens).

I'm

➜  gcloud container images list
NAME
gcr.io/ahmetb-starter/coffeedirectory
gcr.io/ahmetb-starter/foo
gcr.io/ahmetb-starter/userdirectory
gcr.io/ahmetb-starter/web
➜  reg tags gcr.io/ahmetb-starter/web

➜  reg tags gcr.io/ahmetb-starter/non-existing . image
FATA[0000] invalid character '<' looking for beginning of value

➜  reg tags gcr.io/ahmetb-starter/adsfadsfadsf

➜  

I'm getting empty output for images that actually has tags. What am I doing wrong? reg tags --help doesn't reveal much info.

I suppose this has something to do with the way GCR works. reg -r https://gcr.io ls took forever as well. Probably has something to do with GCR API.

$ reg -d -r https://gcr.io ls

Actually figured out:

$ reg -d -r https://gcr.io tags ahmetb-starter/coffeedirectory

It would be better if hostname was actually parsed from image name IMO instead of -r.
