ldap_sync_users as cronjob

Hi,

I’m currently trying to make the ./manage.py ldap_sync_users a cronjob within a docker container so the application im builing gets synced every x hours.

My problem however is that the command wont execute through the cronjob, also I’m well aware this might not be the proper place to ask since the issue lies most likely within cron but I don’t know where else to ask.

If I run any other ./manage.py command like migrate or whatsoever it gives me output and tries to actually do stuff however on ldap_sync_users nothing is happening.

If I run the command by hand within the container everything works like a charm so the problem is within cron I guess.

Anyone have experience with this?

Regards,

I finally made some progress. there was error output, it was just not being redirected right. &>> doesn’t work within crontab, maybe because its sh instead of bash?

by correctly redirecting output with 1> /var/log/cron.log 2> /var/log/cron.err I finally got the error message LDAPOperationsErrorResult now its just a matter of supplying cron with the correct ENV vars.

thanks for the help guys! this issue can be closed 😃

Huh. I’m afraid that I have absolutely no idea why ldap_sync_users might behave differently in cron vs run manually.

If you get to the bottom of this, please let us know what the problem/solution was!

(It’s a good point about getting a “real” scheduler in early rather than later. I guess it’s just cost/benefit based on easy setup with cron, vs time to port over to something else if requirements outgrow cron. The tradeoff point will depend heavily on the sort of project you’re writing regularly. My projects exist in a space where celery is either far too much, or far too little!)

my crontab file looks as following:

• • • • • root python /opt/application/manage.py ldap_sync_users &>> /var/log/cron.log
• • • • • root python /opt/application/manage.py migrate >> /var/log/cron.log

if i add these lines, the ./manage.py migrate executes successfully however the ./manage.py ldap_sync_users does nothing at all. no error messages just nothing, not even a stacktrace or something

i have verified that cron adds and executes the cronjobs from the crontab successfully its just the struggle with ldap_sync_users

thanks again for the quick reply to both of you
