I am having trouble using the COPY and ADD commands in my Dockerfile, for some reason when I do something like this:

ADD . /container/dir
or
ADD whatever.txt /container/dir
or
COPY . /container/dir
The only thing it adds/copies is the Dockerfile, and not the rest of the contents of the build context. I've been poking around the source, but I cannot pinpoint what the issue could be.

Caveat: My docker host is running on a different IP, and the jenkins instance is running inside a container on that host, but I'd think the docker REST client should still work in this case.
