Welcome to this blog!๐ป๐ The primary goal here isnโt to delve deeply into the code but to demonstrate how to efficiently use Docker Compose๐ณ to deploy a web application, including the deployment process, using Flask๐, MongoDB๐๏ธ, and Nginx๐.
Why use Docker Compose?๐ณ
Docker Compose is a game-changer for managing complex Docker applications with multiple containers๐ .๏ธ Instead of juggling multiple Docker commands, you can define and configure all your services in a single docker-compose.yml file๐. This makes it easy to create, start, stop, and scale your entire application with just one command๐ฅ.
Takeaways from this Blog๐
- Simplified management: Docker Compose makes it easy to manage multiple containers as a single unitโ๏ธ
- Consistent environments: Ensure your application runs consistently across different environments๐ฆ
- Efficient deployment: Deploy your full-stack application with a few simple commands๐
- Isolated components: Docker containers provide isolation, preventing conflicts between services๐
- Declarative configuration: Define your applicationโs desired state in a YAML file๐
- Scalability: Easily scale up or down individual services based on demand๐
Prerequisites๐ ๏ธ
Before you start, make sure you have Docker and Docker Compose installed on your system. These tools are essential for building and running the containers for your application.
Dive In!๐
The application is all set up and ready to go. Just clone the repository, build the Docker images, and start the containers. Youโre minutes away from getting everything up and running with Docker Compose!โ๏ธ๐ณ
Clone the repository to your machineโฌ๏ธ:
git clone https://github.com/niranyadav03/dockerized-python-application.git
Project Structure ๐:
Project structure should look like this:
dockerized-python-application/
โโโ app
โ โโโ app.py
โ โโโ Dockerfile
โ โโโ requirements.txt
โ โโโ templates
โ โโโ index.html
โโโ docker-compose.yml
โโโ nginx
โโโ default.conf
โโโ Dockerfile
Navigate to the Project Directory๐:
cd dockerized-python-application
Build and Run the Containers๐ข:
docker-compose up --build
Noteโ ๏ธ: Make sure to run the build commands from the dockerized-python-application directory๐. This is important because the Docker Compose file (docker-compose.yml) and other essential files are located there๐. Running the build from this directory ensures that Docker Compose can access everything it needs to set up the services properly๐ ๏ธ.
Access the Application๐:
Once the containers are up and running, you can access the application.
Web UI๐: Open http://localhost in your browser to view the To-Do List app.
After using the To-Do List application through the UI, make sure everything is working properly by checking the MongoDB database to confirm itโs storing your data correctly๐
Enjoy exploring your new setup with Docker Compose! ๐
Happy Deploying! ๐
