How do I run a cronjob with a python virtual environment?

Question

Usually I SSH into my EC2 instance and run:

source MYVENV/bin/activate

How do I set my cronjob to activate the virtual environment? My Django sc

Answer 1

you can create a single wrapper bash script for executing your Django script. See the example below.

#!/bin/bash -l       // this should pick up your ~/.bash_profile environment variables

cd /path to project dir/   // set it up if your project is not in python path

source /Users/<user>/.virtualenvs/dslab/bin/activate // this activates your environment 

python /home/script.py   // run your script

Answer 2

you can just run the python interpretor from your environment directly eg

MYENV/bin/python script.py

to find out what is the directory to your environment python interpretor, change into the virtual env then run

which python

in your case, this should become

*/1 * * * * /home/ec2-user/MYVENV/python /home/script.py

Answer 3

create a shell script eg scripts.sh

#!/bin/bash
source /home/user/MYVENV/bin/activate
python /path/to/file/script.py

Then in cron put

*/1 * * * * bash /path/to/shell/script/scripts.sh

The script will load all your environment variables and execute from the python in your environment
