Airflow Verified Download File From Url Info

The most flexible way to download a file is by writing a custom Python function and executing it with the PythonOperator . This method uses the standard requests library to fetch the file and save it to a local directory.

from airflow.operators.bash import BashOperator download_bash = BashOperator( task_id='download_with_wget', bash_command='wget -O /tmp/downloaded_file.zip https://example.com' ) Use code with caution.

For simple downloads where you don't want to manage Python dependencies, you can use the BashOperator to run standard CLI tools like wget or curl . The most flexible way to download a file

import requests from airflow import DAG from airflow.operators.python import PythonOperator from datetime import datetime def download_file_func(url, save_path): response = requests.get(url) with open(save_path, 'wb') as f: f.write(response.content) print(f"File downloaded to {save_path}") with DAG('download_dag', start_date=datetime(2023, 1, 1), schedule_interval='@daily') as dag: download_task = PythonOperator( task_id='download_file', python_callable=download_file_func, op_kwargs={ 'url': 'https://example.com', 'save_path': '/tmp/data.csv' } ) Use code with caution. 2. Using the HttpToS3Operator (Direct to S3) Best Practices for File Downloads Operators — Airflow 3

: Streamlines the process by avoiding the local filesystem and using Airflow's built-in http_conn_id and s3_conn_id . 3. Using BashOperator with wget or curl

If your goal is to move a file directly from a URL to an Amazon S3 bucket, the HttpToS3Operator is the most efficient choice. It eliminates the need for manual file handling and integrates directly with Airflow connections.

To download a file from a URL using , you can use several methods depending on your target storage—whether it's the local filesystem, Amazon S3, or Google Cloud Storage (GCS). 1. Using the PythonOperator (Local Filesystem)
