Cron

You can use a specific container to run your Cron jobs:

servers:
  cron:
    hosts:
      - 192.168.0.1
    cmd:
      bash -c "(env && cat config/crontab) | crontab - && cron -f"

This assumes that the Cron settings are stored in config/crontab. Cron does not automatically propagate environment variables, the example above copies them into the crontab.
