deployment/dockerfiles/py/Dockerfile

FROM python:3.7

ADD . .

RUN pip3 install --upgrade pip pbr && pip3 install --no-cache-dir --compile --editable .

This is the simple, but I don't know why it stuck somewhere when I try to build image.

$ docker build -f deployment/dockerfiles/py/Dockerfile .

Since default dir in the container is root: / I would recommend making the following changes to Dockerfile

FROM python:3.7

# then scope of work is just reduced to this directory
WORKDIR /mypackage

ADD . .
RUN pip3 install --upgrade pip pbr && pip3 install --no-cache-dir --compile --editable .
