Syntaxnet spec file and Docker?

[Jedi Knight]

I'm trying to learn Synatxnet. I have it running through Docker. But I really dont know much about either program Synatxnet or Docker. On 

the Github Sytaxnet page it says 

> The SyntaxNet models are configured via a combination of run-time

> flags (which are easy to change) and a text format TaskSpec protocol

> buffer. The spec file used in the demo is in

> syntaxnet/models/parsey_mcparseface/context.pbtxt.

How exactly do I find the spec file to edit it?

I compiled SyntaxNet in a Docker container using this Dockerfile

   

 FROM java:8
   
    ENV SYNTAXNETDIR=/opt/tensorflow PATH=$PATH:/root/bin
   
    RUN mkdir -p $SYNTAXNETDIR \
        && cd $SYNTAXNETDIR \
        && apt-get update \
        && apt-get install git zlib1g-dev file swig python2.7 python-dev python-pip -y \
        && pip install --upgrade pip \
        && pip install -U protobuf==3.0.0b2 \
        && pip install asciitree \
        && pip install numpy \
        && wget https://github.com/bazelbuild/bazel/releases/download/0.2.2b/bazel-0.2.2b-installer-linux-x86_64.sh \
        && chmod +x bazel-0.2.2b-installer-linux-x86_64.sh \
        && ./bazel-0.2.2b-installer-linux-x86_64.sh --user \
        && git clone --recursive https://github.com/tensorflow/models.git \
        && cd $SYNTAXNETDIR/models/syntaxnet/tensorflow \
        && echo "\n\n\n" | ./configure \
        && apt-get autoremove -y \
        && apt-get clean
   
    RUN cd $SYNTAXNETDIR/models/syntaxnet \
        && bazel test --genrule_strategy=standalone syntaxnet/... util/utf8/...
   
    WORKDIR $SYNTAXNETDIR/models/syntaxnet
   
    CMD [ "sh", "-c", "echo 'Bob brought the pizza to Alice.' | syntaxnet/demo.sh" ]
