What I'm trying to do is to run flask command in crontab on Azure App Service with linux App Service Plan.
So far I have my startup.sh to setup cron but the command does not execute, nothing in the logs.
# startup.sh
#!/bin/sh
apt-get update -qq
apt-get install gcc -yqq
apt-get install g++ -yqq
source antenv/bin/activate
pip install -r requirements.txt
apt-get install cron -yqq
service cron start
(crontab -l 2>/dev/null; echo "*/5 * * * * /home/site/wwwroot/antenv/bin/python -m flask db update_migrations")|crontab
gunicorn --bind=0.0.0.0 --workers=4 startup:app
When I was trying to execute the command via SSH I had to install requirements and then, the command itself was working
> /home/site/wwwroot/antenv/bin/python -m flask db update_migrations
but in the crontab it does not want to.
How to debug it, where to find the problem.
Thank you for your help!
