This is a simple Flask application that provides an API endpoint to fetch the temperature of a city from OpenWeatherMap. The application can be Dockerized for easy deployment.

• Python (>= 3.8)
• Docker

git clone https://github.com/yourusername/weather-api.git

1. Visit OpenWeatherMap and sign up for an account.
2. Obtain your API key from the dashboard.

docker build -t weather-api .
docker run -p 5000:5000 -e OPENWEATHER_API_KEY=<your_openweather_api_key> weather-api

Replace <your_openweather_api_key> with your actual OpenWeatherMap API key.

Access the API endpoint at http://localhost:5000/temperature.

• Endpoint: /temperature
• Method: GET
• Parameters:
  • city (required): Name of the city.
  • units (optional): Temperature units (imperial or metric). Defaults to metric.

curl http://localhost:5000/temperature?city=London&units=metric

{
  "city": "London",
  "temperature": 20.5,
  "units": "metric"
}

To test your Weather API endpoint with the provided script, use the following command:

python test_script.py --endpoint http://your-api-endpoint/temperature # This will default to localhost if you don't specify, so only add if necessary
