You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip install face_recognition' returned a non-zero code: 1

My docker file:

FROM ubuntu:16.04

# Update

# Install app dependencies
RUN apt-get update && apt-get install -y \
    python-pip
RUN pip install face_recognition

# Bundle app source
COPY . /usr/src/app
CMD ["python", "face.py"]

You need additional things installed to compile dlib.

Instead of starting from scratch, you can just use the sample Dockerfile I provided with the code: https://github.com/ageitgey/face_recognition/blob/master/Dockerfile
