Only trigger on cron

[Seb Boving]

I have some jobs I only want to trigger via cron.  In a Github project, I can't seem to disable the triggers via commits (unless I disable the branch in which case cron's also don't run) in the job configuration.

Another way that could perhaps work is if the trigger type would be exposed within the pipeline steps (i.e through env vars).

Is there some way of doing this I am missing?  Should I use a different job type for this (while still having the convenience of having a Jenkinsfile in Github) and if so which?

thanks,
