An ideal way of installing dependencies while building a container Using a Dockerfile. Store dependencies in a file, copy it and then RUN install on that from within the related Dockerfile.

Dockerfile

FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN mkdir /config
ADD /requirements.txt /config/
RUN pip install -r config/requirements.txt;
RUN mkdir /src;
# Create Log Directories
RUN mkdir /logs;
RUN mkdir /logs/rest_api;
# Create Log File Placeholders: dev and prod.
RUN touch /logs/rest_api/dev;
RUN touch /logs/rest_api/prod;
WORKDIR /src
