هل يمكنني تشغيل مهمة cron كمستخدم Postgres؟

الدعم تثبيت

لديّ عدد من الاستعلامات التي تحتاج إلى تشغيل كل ليلة. ظننت أنني أستطيع القيام بالتالي:

cd /var/discourse
./launcher enter app
su postgres
crontab -e
... أضف مهامّي واحفظ ...

لكنني حصلت على خطأ:

postgres@EN-Discourse-Forums-app:~$ crontab -e
crontab: installing new crontab
crontab: crontabs/postgres: rename: Operation not permitted
crontab: edits left in /tmp/crontab.7kGYwA/crontab

هل هذا ممكن؟

The more “Discourse-way” of doing that would be creating a plugin with the queries as scheduled jobs.

Check this example:

Inside the execute block you can do anything, like this job who runs SQL:

Potentially, yes, but this doesn’t let others who may need to change the behavior of these queries and our servers use something they understand. It is very common to use CRON to run queries.

Did you read How to add a job to cron/anacron when creating Docker container ?
