Creating a Dockerfile for a Django project

A Dockerfile is a text document that has all the instructions needed to create a Docker image. We can consider a Dockerfile as a recipe that we can follow to cook any item.

# Pull the official base image
FROM python:3.11
# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
# Install different Linux packages.
RUN apt-get update \
&& apt-get install gcc postgresql postgresql-contrib libpq-dev python3-dev netcat-traditional -y \
&& apt-get clean
# set working directory and install packages using pip.
WORKDIR /app
COPY ./requirements ./requirements
RUN pip install -r requirements/requirements-local.txt
# Copy the Application code
COPY . /app/
COPY ./entrypoint.sh /app/entrypoint.sh
# Give permission to entrypoint.sh file as executable.
RUN chmod...
