What's the best way to run a python script daily?

Question

I have a python script that connects to Redshift, executes a series of SQL commands, and generates a new derived table.

But for the life of me, I can't figure out a way to have it automatically run every day.

I've tried AWS Data Pipeline but my shell script won't run the first copy statement. I can't get Lambda or Glue to work because my company's IAM policies are restrictive. Airflow seems like overkill to just run a single python script daily.

Any suggestions for services to look into?

Answer 1

Cron job?

00 12 * * * /home/scottie/bin/my_python_script.py

Run my_python_script.py at the top of the hour (0th minute), at noon, every day.

Answer 2

I use a scheduled task on Windows. Either enter it using the GUI or the at command .

Answer 3

If you are using AWS Glue or have some other reason to install a development endpoint, you can use Apache Zeppelin to run any code from any language (if you have the jar files) on a schedule based on a cron command. Here's the notebook I use to run Redshift nightly maintenance:

在ec2实例上使用cron作业或设置调度事件来调用你的aws python lambda函数http://docs.aws.amazon.com/lambda/latest/dg/with-scheduled-events.html
