Dockerizing a simple Django app
Docker is a set of the platform as service products that use OS-level virtualization to deliver software in packages called containers(namespace). here, we are dockerizing a simple user login and sign up Django project. The project we are using too dockerized is Sign Up and log in
To download source code use
$ git clone https://github.com/itsvinayak/user_login_and_register.git
The next step is to add Docker to it. So, create an empty file named Dockerfile and put this code inside it
$ touch Dockerfile
now edit it.
FROM python:3.6 RUN apt-get update \ && apt-get install -y --no-install-recommends \ && rm -rf /var/lib/apt/lists/* WORKDIR /usr/src/app COPY requirements.txt ./ RUN pip install -r requirements.txt COPY . . EXPOSE 8000 CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
Now we need to build our Docker image and run it. This can be done by the following command :
to build image
$ sudo docker build -t image_name .
to see if image exit use and you can see all your images.
$ sudo docker images
to run docker application use
$ sudo docker run -p 8000:8000 image_name
