Deploy Django and MySQL using docker compose Complete Course to Deploy Container for Django and MySQL with Docker Compose | DevOps | Docker Tamil Pre-Requisites to Deploy Container for Django and MySQL Install Docker Install Docker Compose Python 3.x or later To Install Docker in ubuntuhttps://docs.docker.com/engine/install/ubuntu/ 1. Update the apt package index and install packages to allow apt to use a repository over HTTPS: $ sudo apt-get update $ sudo apt-get install \ ca-certificates \ curl \ gnupg 2. Add Docker’s official GPG key: $ sudo install -m 0755 -d /etc/apt/keyrings $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg $ sudo chmod a+r /etc/apt/keyrings/docker.gpg 3. Use the following command to set up the repository: $ echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null Install Docker Engine Update the apt package index: sudo apt-get update Install Docker Engine, containerd, and Docker Compose. To install the latest version, run: $ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin Verify that the Docker Engine installation is successful by running the hello-world image: sudo docker run hello-world Setting the Project Folder Directory Create a project folder as "django-container-app" $ mkdir django-container-app Create a virtual env for django application in python $ python3 -m venv django_app Activate the virtual env for django application in Linux Ubuntu $ source /django-app/bin/activate Installing the django into the venv using pip or pip3 $ pip install django create a django project inside the venv $ django-admin startproject docker-app . Now, go to the docker-app/settings.py. Add the ip address to the ALLOW_HOSTS ALLOW_HOSTS = ["0.0.0.0",,] - to access outside of the vm, - to access inside the vm Now, create a requirements.txt file, to install necessary python package inside the container Django sqlparse psycopg2-binary pytz asgiref mysqlclient Now, create the Dockerfile to Deploy Python Django App # Use an official Python runtime as a parent image FROM python:3.9 ARG APP_PORT ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 # Set the working directory to /code WORKDIR /code COPY requirements.txt requirements.txt # Install any needed packages specified in requirements.txt RUN pip install --no-cache-dir --upgrade pip && \ pip install --no-cache-dir -r requirements.txt COPY . /code # Run migrations RUN python manage.py makemigrations && python manage.py migrate # Expose port 8000 for the Django app EXPOSE $APP_PORT CMD [ "python","manage.py","runserver","0.0.0.0:8000" ] Now, create a docker-compose.yam file, to deploy multiple micro services container like Django as django_app as a container name, MySQL as django_db as a container name version: '3' services: db: image: mysql:latest container_name: pure_db environment: DB_HOST: db MYSQL_DATABASE: sample_db MYSQL_USER: sample_user MYSQL_PASSWORD: sample_password MYSQL_ROOT_PASSWORD: sample123 restart: always ports: - 3306:3306 app: build: context: . dockerfile: Dockerfile container_name: pure_app environment: DB_HOST: db DB_NAME: sample_db DB_USER: sample_user DB_PASSWORD: sample_password ports: - 8001:8000 depends_on: - db links: - db Now, Deploy the Docker container using docker-compose commands $ docker-compose up Go to the browser, and type http://192.168.0.8:8001 Thus, Succesfully, Deployed the Django and MySQL container
