Execute Python Script via Crontab

Crontab Configuration

To execute a Python script using crontab, edit the crontab file using the command crontab -e. Append the following line to the end of the file:

*/10 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py

This line specifies that the script should be executed every 10 minutes. The crontab syntax is as follows:

• Minute (0-59)
• Hour (0-23)
• Day of Month (1-31)
• Month (1-12 or month name)
• Day of Week (0-6 or day name)

Script Considerations

The Python script provided in the question uses the pycurl library to interact with the OpenStack API. It monitors the status of existing servers and creates new servers if certain conditions are met.

File Editing

To configure the cronjob, you only need to edit the crontab file by running crontab -e. No additional file edits are necessary.
