Hi,

I am new to docker containers and getting an error while trying to build a docker image. Below is the docker file and requirement.txt for that:

Docker file:

FROM joyzoursky/python-chromedriver
WORKDIR /app
COPY . /app
RUN pip install --upgrade pip
RUN pip install virtualenv --upgrade
RUN pip install --trusted-host pypi.org -r requirements.txt
EXPOSE 80
ADD SeleniumTest.py /SeleniumTest.py

requirement.txt:

azure-storage-blob==1.4.0
selenium==3.141.0
bs4==0.0.1

Now the issue that I am facing is while trying to install azure-storage-blob package I am getting errors. But If I remove it from requirement.txt I am successfully able to build the docker image.
Below is the complete stack trace of the error which I am getting. Any ideas on why I am getting errors only when I try to install "azure-storage-blob" package?
