Renamed the nightly image to DNX

[vlesierse]

The ASP.NET 5 team has renamed KRE, KVM to DNX, DNVM. This pull request will make the nightly image to adapt to these changes.

Currently the k and kpm command are still usable, but this shouldn't affect the nightly image in the future.

Example Dockerfile

FROM aspnet:nightly

COPY . /app
WORKDIR /app
RUN kpm restore
ENV DNX_TRACE 1
ENTRYPOINT sleep 10000 | k kestrel

Looks good to me, have you tried manually running any applications on this image? We took it out of CI therefore we have no way to know if it's working or not. Thanks @vlesierse

[vlesierse]

Yeah, I have run my own project and the HelloWeb sample from the Home repository successfully using these changes.

[ahmetb]

thanks @vlesierse. For some reason master is broken after merge... Although that probably has nothing to do with nightly.

[vlesierse]

Interesting since it is the beta 1 image. I notice that the kpm restore command resolves NuGet packages with the version beta 3.

😕 what to do now?

[vlesierse]

Working on a fix. I'm planning to checkout the according tag in the repo like the nightly image did before.
