. (as in single dot symbol, followed by space) in shell is equivalent of
source command, so basically you are trying to execute every line in you python script as shell command, which is certainly not something you want to do.
The proper way to execute you script, assuming
chmod +x was set is
@reboot /home/ubuntu/config.py @reboot /home/ubuntu/start_elastic.py
However, for clarity i’d recommend explicitly declaring interpreter in cronjob, like this
@reboot /usr/bin/python3 /home/ubuntu/config.py @reboot /usr/bin/python3 /home/ubuntu/start_elastic.py
