go-cron - A user-land cron alternative for use in Docker containers

This app reads a crontab file and makes runs it just like crond would. The reason this app was created is specifically geared towards the use in a Docker container:

• go-cron can run as non-root (crond wants to create a PID file and can only run as root)
• go-cron can run with per second accuracy if the crontab has 6 time fragments
• go-cron is not strict about the ownership and permissions of the crontab files.

Building

1. Build a binary using go build
2. Now you have go-cron as an executable binary

Usage

./go-cron -file crontab.txt

Consider using dumb-init to prevent zombie processes. I'm not sure if it is needed, as my understanding of the init system is limited, but using dumb-init does not hurt either.

/usr/bin/dumb-init -- ./go-cron -file crontab.txt
