README

Babycron

Build Status

Run a single cron job in the foreground, sending output to stdout. Works well in Docker.

Usage

Pass two arguments: the cron schedule and a string of the task to run.

# Run a script every minute
babycron '*/1 * * * *' 'sh path/to/script.sh'

# Run a script on start, and then again every six hours
babycron --run-on-start '0 */6 * * *' 'sh path/to/script.sh'

# Gzip and backup a Redis DB every day at midnight
babycron '0 0 * * *' 'cat /data/dump.rdb | gzip | pipedream -b backups -p backup.rdb.gz'

Note that if you’re running a script you must include the interpreter in the second argument (i.e. sh or /bin/sh), regardless if you have a #! and executable permissions. Babycron will search your PATH, so things like bash or sh, without the full path to the interpreter, is usually fine.

In Docker:

ENTRYPOINT [ "babycron", "* * * * *", "sh path/to/script.sh" ]

Output and errors are sent to stdout, so they'll appear in your Docker logs.

brew tap meowgorithm && brew install babycron
