djangae wont run on docker

[crowne]

After inheriting from the rehabstudio/djangae Dockerfile and running the image, I get the following error:

---

Please switch to runtime: custom.
The devappserver does not actually use your Dockerfile, so please use either the --runtime flag to specify the runtime you want or use the --custom_entrypoint flag to describe how to start your application.

This is a 'feature' of newer appengine SDK versions which add support for Docker (by detecting the Dockerfile). We should have an ONBUILD method which solves this. In the meantime, in your child Dockerfile, use RUN rm /src/Dockerfile to have devappserver return to it's original behaviour.
