Chronos is a distributed, fault-tolerant job scheduler that runs on Apache Mesos as a replacement for cron. It supports ISO8601 repeating interval schedules, dependency-based job chains, Docker containers, and provides a web UI with job stats and history.

Use cases

  • schedule recurring jobs across a Mesos cluster instead of cron
  • run jobs with dependencies where a job triggers after its parents complete
  • schedule batch workloads like Hadoop or EMR jobs on Mesos
  • run scheduled jobs inside Docker containers
  • get fault-tolerant leader/follower scheduling with retries and job history

When to choose

  • you already run Apache Mesos or DC/OS and need cron-like scheduling
  • you need dependency chains between scheduled jobs
  • you need fault tolerance, retries, and job stats for scheduled workloads

When to avoid

  • you run Kubernetes instead of Mesos - use Kubernetes CronJobs or Argo Workflows
  • you need a simple single-host cron replacement
  • you need an actively developed scheduler - the project has seen little recent activity
