+-   [Ofelia](https://github.com/mcuadros/ofelia/) - Ofelia is a modern and low footprint job scheduler for docker environments, built on Go. Ofelia aims to be a replacement for the old fashioned cron. Supports configuration from container labels and/or configuration files.
 -   [su-exec](https://github.com/ncopa/su-exec) - This is a simple tool that will simply execute a program with different privileges. The program will be executed directly and not run as a child, like su and sudo does, which avoids TTY and signal issues. Why reinvent gosu? This does more or less exactly the same thing as gosu but it is only 10kb instead of 1.8MB. By [ncopa](https://github.com/ncopa)
 -   [sue](https://github.com/theAkito/sue) - Executes a program as a user different from the user running sue. This is a maintainable alternative to ncopa/su-exec, which is the better tianon/gosu. This one is far better (higher performance, smaller size), than the original gosu, however it is far easier to maintain, than su-exec, which is written in plain C. Made by [Akito][akito]
