Docker compose is a tool using which we can define and run multi-container applications<\/strong>. With docker-compose, we can define configurations using a single YAML file<\/strong> and manage multiple containers using a single command<\/strong>.<\/p>\n

In this blog, we will deploy a Django<\/a> application using docker-compose. In production, a Django application is built with the following components:<\/p>\n

    \n
  1. WSGI server – Gunicorn\u00a0<\/strong><\/li>\n
  2. Web Server – Nginx<\/strong><\/li>\n
  3. Database – PostgreSQL<\/strong><\/li>\n<\/ol>\n

    To package a Django application<\/a> with Docker, Gunicorn, Nginx, and PostgreSQL follow the below steps.<\/p>\n

    Step1: Create Dockerfile for the Django application<\/strong><\/p>\n

    In this blog the directory structure followed is as below.<\/p>\n

    \"\"<\/p>\n

    Go to the directory where Django code is present. Create a file with the name Dockerfile<\/strong> and paste the following code there.<\/p>\n

    FROM python:3.8-slim-buster\r\nENV PYTHONBUFFERED=1\r\nRUN pip install --upgrade pip\r\nWORKDIR \/app\r\nCOPY requirements.txt requirements.txt\r\nRUN pip install -r requirements.txt\r\nCOPY . .\r\nCMD [\"\/bin\/bash\", \"entrypoint.sh\"]\r\n<\/pre>\n
    Create a file entrypoint.sh <\/strong>and paste the following script there. Replace the WSGI module core.wsgi:application<\/strong> according to your application.<\/p>\n
    #!\/bin\/bash\r\n\r\npython manage.py makemigrations --no-input\r\npython manage.py migrate --no-input\r\npython3 manage.py collectstatic --no-input\r\n\r\ngunicorn core.wsgi:application --bind 0.0.0.0:8000\r\n<\/pre>\n
    Step2: Create Dockerfile for Nginx<\/h3>\n
    Go to nginx directory. Create a Dockerfile\u00a0<\/strong>and paste the following code there.<\/p>\n
    FROM nginx:1.19.0-alpine\r\n\r\nCOPY .\/default.conf \/etc\/nginx\/conf.d\/default.conf\r\n<\/pre>\n
    Now create a file default.conf<\/strong> and paste the following code there.<\/p>\n
    upstream django {\r\nserver django_app:8000;\r\n}\r\n\r\nserver {\r\n     listen 80;\r\n \r\n     location \/ {\r\n          proxy_pass http:\/\/django;\r\n          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\r\n          proxy_set_header Host $host;\r\n          proxy_redirect off;\r\n          }\r\n\r\n    location \/static\/ {\r\n        alias \/app\/staticfiles\/ ;\r\n         }\r\n}\r\n<\/pre>\n
    Step3: Create a docker-compose file<\/h3>\n
    Now create a docker-compose.yaml file and paste the following code there.<\/p>\n
    version: \"3.8\"\r\nservices:\r\n   django_app:\r\n     build: .\/djangoapp\r\n     volumes:\r\n       - staticfiles:\/app\/staticfiles\r\n     ports:\r\n       - 8000:8000\r\n     image: app:django\r\n     depends_on:\r\n      - pgdb\r\n     restart: \"on-failure\"\r\n\r\n   nginx:\r\n     build: .\/nginx\r\n     volumes:\r\n       - staticfiles:\/app\/staticfiles\r\n     ports:\r\n       - 80:80\r\n     image: nginx:django\r\n     depends_on:\r\n       - django_app\r\n     restart: \"on-failure\"\r\n\r\n   pgdb:\r\n     image: postgres:13\r\n     volumes:\r\n       - pg_data:\/var\/lib\/postgresql\/data\/\r\n     environment:\r\n       - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}\r\n       - POSTGRES_DB=${DB_NAME}\r\n       - POSTGRES_USER=${POSTGRES_USER}\r\n     restart: \"on-failure\"\r\n\r\nvolumes:\r\n   staticfiles:\r\n   pg_data:\r\n\r\n<\/pre>\n
    Next, create a .env file and add the Postgres environment variables to it.<\/p>\n
    POSTGRES_PASSWORD=postgres_pass\r\nDB_NAME=postgres_db\r\nPOSTGRES_USER=postgres_user\r\n<\/pre>\n
    Step4: Start the application<\/p>\n
    Use the following command to build the images and start the containers.<\/p>\n
    docker compose up --build\r\n<\/pre>\n
    \"docker<\/p>\n
    To run the containers in the background use -d<\/strong> flag.<\/p>\n
    docker compose up -d\r\n<\/pre>\n
    \"docker<\/p>\n
    Now you can access your application from the browser.<\/p>\n
