unclcd/cron repository overview

⁠Cron

Image based on python:3.7-slim for running periodic task with cron.

⁠Usage

1. Add a file called scheduler.crontab to image root

    FROM unclcd/cron:latest
    COPY scheduler.crontab /scheduler.crontab
   

   Copy

2. The file scheduler.crontab should contain a line for every task following crontab sintaxis. Also the file should contain a last line, and every command should be redirected to /proc/1/fd/1 2>/proc/1/fd/2 for its output to be redirected to container standard output. For instance:

    * * * * * your_command > /proc/1/fd/1 2>/proc/1/fd/2
    # This extra line makes it a valid cron
    
   

   Copy

3. Ensure your command and every dependency are available in the correct path.
