How to server Django media files on apache2 and docker

I'm Running a django app on apache2 using docker, everything works great but when i try to open an uploaded file ( media file) it says an URL not found error like : physical/path/to/file/filename.jpg doesnt exsits so it converts the url to a phyical path from inside the docntainer..

Here are my files:

DockerFile

ARG DEBIAN_FRONTEND=noninteractive
ENV TZ=Africa/Cairo

RUN apt-get install -y apt-utils vim curl apache2 apache2-utils
RUN apt-get -y install python3 libapache2-mod-wsgi-py3
RUN ln /usr/bin/python3 /usr/bin/python
RUN apt-get -y install python3-pip
#Add sf to avoid ln: failed to create hard link '/usr/bin/pip': File exists
RUN ln -sf /usr/bin/pip3 /usr/bin/pip
RUN pip install --upgrade pip
RUN pip install django ptvsd

RUN pip install -r requirements.txt
