.dockerignore contain files which should not be copied by COPY command, so this files should not be in produced image. Dockerfile should not be in produced image, so it should be in .dockerignore.

How do you figured out that image wont build if Dockerfile is in .dockerignore?

It builds fine at least on version 1.0.1, build 990021a

[Sergey Skripnick (eyerediskin)]

Yeah, there is a bug in docker-1.2.0

https://github.com/docker/compose/issues/1329

So we should keep .dockerignore without Dockerfile if we want to support buggy docker version
