Cron job definition

hi I am trying to define a custom cron job. Can you help me with the correct syntax. Tried a few things but this is the idea:

    - foo
  - cron
  - * * * * *

a few thoughts:

  1. cron jobs are defined in the user interface (settings screen) or using the command line tools. They are not defined in the yaml, although you can limit which pipelines or pipeline steps are executed by named cron jobs. For more information please see
  2. the trigger section would specify the name of the existing cron jobs, not the cron expression syntax
  3. the cron expression syntax must include seconds (6 space-separated fields) as shown in the documentation
