About Supercronic
Supercronic runs jobs from a standard crontab file, but it is designed for containers rather than full servers. Typical server cron implementations are a poor fit for containers, and Supercronic exists to fill that gap.
You can keep the familiar crontab syntax and run the jobs in a container image. The repository includes Prometheus metrics support and a process reaper. It suits developers and operators who need cron-style scheduling inside Docker or similar environments.
