docker build fails as it takes a "/" in the image tag

[vikas027]

I have a very simple Dockerfile for testing.

$ cat Dockerfile
FROM alpine:3.4
ENV TIMEZONE=Australia/Sydney
$

horatio fails as it takes a "/" in the image tag. I am experiencing this issue in ruby versions 2.2.2 and 2.3.0.

$ cat horatio.json
{
  "name": "misc-project",
  "version": "0.0.1"
}
$

$ horatio

Looks like it is required to use a -r or --registry switch.
