(You can use either a `.yml` or `.yaml` extension for this file.) + +1. Create an empty project directory. + + You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image. + +2. Create a new file called `Dockerfile` in your project directory. + + The Dockerfile defines an application's image content via one or more build + commands that configure that image. Once built, you can run the image in a + container. For more information on `Dockerfile`, see the [Docker user guide](https://docs.docker.com/get-started/) + and the [Dockerfile reference](https://docs.docker.com/engine/reference/builder/). + +3. Add the following content to the `Dockerfile`. + + ```dockerfile + # syntax=docker/dockerfile:1 + FROM python:3 + ENV PYTHONDONTWRITEBYTECODE=1 + ENV PYTHONUNBUFFERED=1 + WORKDIR /code + COPY requirements.txt /code/ + RUN pip install -r requirements.txt + COPY . /code/ + ``` + + This `Dockerfile` starts with a [Python 3 parent image](https://hub.docker.com/r/library/python/tags/3/). + The parent image is modified by adding a new `code` directory. The parent image is further modified + by installing the Python requirements defined in the `requirements.txt` file. + +4. Save and close the `Dockerfile`. + +5. Create a `requirements.txt` in your project directory. + + This file is used by the `RUN pip install -r requirements.txt` command in your `Dockerfile`. + +6. Add the required software in the file. + + ```python + Django>=3.0,<4.0 + psycopg2>=2.8 + ``` + +7. Save and close the `requirements.txt` file. + +8. Create a file called `docker-compose.yml` in your project directory. + + The `docker-compose.yml` file describes the services that make your app. In + this example those services are a web server and database. The compose file + also describes which Docker images these services use, how they link + together, any volumes they might need to be mounted inside the containers. + Finally, the `docker-compose.yml` file describes which ports these services + expose. See the [`docker-compose.yml` reference](https://docs.docker.com/compose/compose-file/) for more + information on how this file works. + +9. Add the following configuration to the file. + + ```yaml + services: + db: + image: postgres + volumes: + - ./data/db:/var/lib/postgresql/data + environment: + - POSTGRES_DB=postgres + - POSTGRES_USER=postgres + - POSTGRES_PASSWORD=postgres + web: + build: . + command: python manage.py runserver 0.0.0.0:8000 + volumes: + - .:/code + ports: + - "8000:8000" + environment: + - POSTGRES_NAME=postgres + - POSTGRES_USER=postgres + - POSTGRES_PASSWORD=postgres + depends_on: + - db + ``` + + This file defines two services: The `db` service and the `web` service. + + > Note: + > + > This uses the build in development server to run your application + > on port 8000.

Save and close the `docker-compose.yml` file. + +## Create a Django project + +In this step, you create a Django starter project by building the image from the build context defined in the previous procedure. + +1. Change to the root of your project directory. + +2. Create the Django project by running the [docker compose run](https://docs.docker.com/engine/reference/commandline/compose_run/) + command as follows. + + ```console + sudo docker compose run web django-admin startproject composeexample . + ``` + + This instructs Compose to run `django-admin startproject composeexample` + in a container, using the `web` service's image and configuration. Because + the `web` image doesn't exist yet, Compose builds it from the current + directory, as specified by the `build: .` line in `docker-compose.yml`. + + Once the `web` service image is built, Compose runs it and executes the + `django-admin startproject` command in the container. This command + instructs Django to create a set of files and directories representing a + Django project. + +3. After the `docker compose` command completes, list the contents of your project. + + ```console + $ ls -l + + drwxr-xr-x 2 root root composeexample + drwxr-xr-x 3 root root data + -rw-rw-r-- 1 user user docker-compose.yml + -rw-rw-r-- 1 user user Dockerfile + -rwxr-xr-x 1 root root manage.py + -rw-rw-r-- 1 user user requirements.txt + ``` + + If you are running Docker on Linux, the files `django-admin` created are + owned by root.
