Perfect for staying on top of weather changes and preparing for unexpected conditions! 🚀 + +## Features + +- **Fetch Weather Data**: Retrieves up-to-date weather information for any city using the OpenWeatherMap API. +- **Custom Alerts**: Set your own temperature and wind speed thresholds. If the weather conditions exceed these, the script will alert you! +- **Hourly Updates**: The script automatically checks the weather every hour, so you’re always in the loop. +- **User Input for City**: Now includes a web form for users to input their desired city, making it easier to get real-time weather alerts for specific locations. +- **Dynamic Web Application**: The application runs on Flask, serving a simple web interface to display alerts. + +## Getting Started + +### Prerequisites + +- Python 3.x +- `requests`, `python-dotenv`, and `Flask` libraries + +Install the required libraries using: + +```bash +pip install requests python-dotenv Flask +``` + +## Setup + +- Clone or download this repository. +- Get an API key from OpenWeatherMap. (It’s free!) +- Create a `.env` file in the root directory and add your API key like shown in `.env.example` +- To run the web application, execute the following command: + +```bash +python main.py +``` + +- Access the application by navigating to `http://localhost:80` in your web browser. + +## Docker Setup + +To run the application using Docker: + +1. Ensure Docker is installed on your machine. +2. Build the Docker image: + +```bash +docker build -t weather-app . +``` + +3. Run the Docker container: + +```bash +docker run -it -p 80:80 -e OPEN_WEATHER_MAP_API_KEY=your_api_key -e CITY="Your City" -e TEMP_THRESHOLD=30 -e WIND_SPEED_THRESHOLD=10 weather-app +``` + +## Troubleshooting + +- **Missing API Key Error**: Double-check that your `.env` file contains the correct `OPEN_WEATHER_MAP_API_KEY`. Make sure there are no typos or extra spaces. +- **Error fetching data**: This could happen if the API key is incorrect or if the city name is misspelled. Verify both and try again. +- **Internal Server Error**: Ensure that the `index.html` file is present in the correct directory and that the Flask app is properly set up to render it. + +## Future Improvements + +- Consider deploying the application to a cloud platform for wider accessibility. +- Implement AJAX to allow for real-time updates without requiring a page refresh. +- Suggestion: Explore developing this application using Django for better structure and scalability. I would be happy to assist in making improvements in that framework. + diff --git a/Weather Alert/Amitabh-DevOps/Weather-Alert-Dockerfile-Web/main.py b/Weather Alert/Amitabh-DevOps/Weather-Alert-Dockerfile-Web/main.py new file mode 100644 index 0000000..976ce1f --- /dev/null +++ b/Weather Alert/Amitabh-DevOps/Weather-Alert-Dockerfile-Web/main.py @@ -0,0 +1,67 @@ +from flask import Flask, render_template, request +import requests +import os +import logging +from dotenv import load_dotenv + +app = Flask(__name__) + +# Load environment variables from .env file +load_dotenv() + +# Load API key from environment variable +API_KEY = os.getenv('OPEN_WEATHER_MAP_API_KEY') + +if not API_KEY: + raise ValueError("Missing environment variable 'OPEN_WEATHER_MAP_API_KEY'") + +UNIT = 'metric' +BASE_URL = 'https://api.openweathermap.org/data/2.5/find' + +# Set up basic logging +logging.basicConfig(level=logging.INFO) + +@app.route('/', methods=['GET', 'POST']) +def index(): + alerts = [] + if request.method == 'POST': + city = request.form.get('city', '').strip() + if city: + weather_data = fetch_weather(city) + alerts = check_alerts(weather_data) + return render_template('index.html', alerts=alerts) + +def fetch_weather(city): + """Fetches weather data for a given city.""" + url = f"{BASE_URL}?q={city}&appid={API_KEY}&units={UNIT}" + logging.info(f"Fetching weather for {city}: {url}") # Log the URL being called + response = requests.get(url) + if response.status_code == 200: + return response.json() + else: + logging.error(f"Error fetching data: {response.status_code}, {response.text}") # Log the error response + return None + +def check_alerts(data): + """Checks for temperature and wind speed alerts in weather data.""" + if not data or 'list' not in data or not data['list']: + return ["No data available to check alerts."] + + weather_info = data['list'][0] + temp = weather_info['main']['temp'] + wind_speed = weather_info['wind']['speed'] + + alerts = [] + temp_threshold = float(os.getenv('TEMP_THRESHOLD', 30.0)) # Default to 30°C + wind_speed_threshold = float(os.getenv('WIND_SPEED_THRESHOLD', 10.0)) # Default to 10 m/s + + if temp > temp_threshold: + alerts.append(f"Temperature alert!
