In our exciting journey of containerization and orchestration, we embarked on a mission to deploy a Flask website using Docker Compose. Our goal was to achieve high availability, efficient resource utilization, and seamless traffic distribution. Here’s how we did it:
- Our Flask-based website was the heart of our application. It provided dynamic content and handled user requests.
- We encapsulated our Flask application within three Docker containers. Each container represented an instance of our website.
- These containers were isolated, portable, and easy to manage. Docker allowed us to package our application along with its dependencies, ensuring consistency across different environments.
- This powerful tool allowed us to define our multi-container application in a single docker-compose.yml file.
- We specified our Flask service, and networking details.
- With a simple docker-compose up, our entire stack came to life.
- To distribute incoming traffic across our three Flask servers, we introduced Nginx as our load balancer.
- Nginx acted as the gateway, receiving requests from clients and forwarding them to the available Flask containers.
- Load balancing ensured that no single server was overwhelmed, improving performance and fault tolerance.
