Context Cron job wasn’t running. Couldn’t tell why. I had done the following in the crontab:
Still did not work.
I then found out that I could enable logging for cron by:
[whatever cmd] >> /home/dhruv/projects/prod/cron.log 2>&1
File Descriptor 1 = stdout File Descriptor 2 = stderr
Basically, stdout is being now being redirected to the log file. And the `2>&1’ is redirecting stderr to stdout (which is the log file)
Using this, I found out that my
chromedriver wasn’t on the PATH!
cron has a limited set of environmental variables. You can check by adding a cronjob like so:
* * * * * env > /tmp/env.output
Now you can check which environment variables are set. In my case, only
/bin were set.
chromedriver binary was in
Two ways I could solve this - 1) add
chromedriver to cron’s PATH or 2) change cron’s path to include
I chose to go with 2). This can be done by setting the PATH variable at the top of the crontab:
I just set it to whatever my bash PATH was.
