Supercronic is a crontab-compatible job runner designed specifically for container environments. It preserves environment variables, logs to stdout/stderr, and handles SIGTERM/SIGINT gracefully so cron jobs behave correctly inside containers.

Use cases

• run cron jobs inside docker containers
• schedule periodic tasks in kubernetes pods
• replace system cron in a containerized app
• run scheduled background jobs with container environment variables
• gracefully shut down scheduled jobs on container stop
• log cron job output to container stdout

When to choose

• you need crontab-style scheduling in Docker or Kubernetes
• you want cron jobs to inherit container environment variables
• you need graceful shutdown of running jobs when the container stops
• you want job output logged to stdout/stderr for container log collection

When to avoid

• you need traditional multi-user system cron on a server
• you need distributed or persistent job scheduling across many nodes
• you need sub-second scheduling precision or complex workflow dependencies
