Cronbox

This is a simple image to run a cron scheduler as a docker image.

Structure

<root>
    /bin                    # /bin is added to the $PATH during build
       <your_node_scripts>  # your scripts goes here
    cronbox_schedule        # crontab file used inside the image
    .env                    # environment variables used in scripts with `dotenv`

Usage

Add new scripts

Add scripts inside bin folder. The script should be self-executable. Remove any extension and add a shebang header with executable path (ex: #!/usr/bin/env node for node scripts).

Remember to change exec permission with chmod +x bin/my_awesome_script.

Schedule your script in crontab

Reference your script inside cronbox_schedule file with crontab format.

Example:

0 0/2 * * *  my_awesome_script   # run my_awesome_script every 2 hours
