3. Implementation

Role of Docker in My Project

Create Dockerfile
This is the Dockerfile used in the project:

FROM python:3.10-slim
WORKDIR /app
COPY requirements.txt /app/requirements.txt
RUN pip install -r requirements.txt
COPY . /app
ENTRYPOINT ["python"]
CMD ["app.py"]

Build Docker Image
Use the following command to build the Docker image for the app:
```
docker build -t team2-app .
```

Run Docker Container
To run the container:
```
docker run -d -p 5000:5000 team2-app
```
This exposes the app on port 5000.

Container is running in the docker app

Application is running on http://localhost:5002/team2/
