# Multistage Dockerfile Example for Flask Application
This repository demonstrates the use of a multistage Dockerfile to build and package a Flask backend application. Multistage builds are used to optimize the final Docker image size and improve security.

## Introduction
Modern application deployments often involve containerizing both the backend and frontend components. This project focuses on using a multistage Dockerfile to efficiently build a Flask backend application, creating a lightweight and secure Docker image.
## Prerequisites
- Docker: You need to have Docker installed on your machine. Visit [Docker's official website](https://www.docker.com/get-started) to download and install Docker.
## Getting Started
1. Clone this repository:
```sh
git clone https://github.com/your-username/multistage-flask-app.git
cd multistage-flask-app
```
2. Build the Docker image:
```sh
docker build -t my-flask-app .
```
## Usage
1. Run the Docker container:
```sh
docker run -p 5000:5000 my-flask-app
```
2. Access the Flask application in your web browser at `http://localhost:5000`.
## Dockerfile Explanation
The multistage Dockerfile consists of two build stages, each optimized for a specific purpose.
### Stage 1: Build the Flask Application
- Use a Python base image to build the Flask backend.
- Copy the backend source code and install dependencies.
- Build the Flask application.
### Stage 2: Final Image
- Use a minimal Python base image for the final image.
- Copy the built backend from Stage 1.
- Expose the necessary port and start the Flask application.
