applyOnlyAtCronInterval

By default, when you update an association, the system runs it immediately after it is updated and then according to the schedule you specified. Specify true for ApplyOnlyAtCronInterval if you want the association to run only according to the schedule you specified.

If you chose this option when you created an association and later you edit that association or you make changes to the Automation runbook or SSM document on which that association is based, State Manager applies the association at the next specified cron interval. For example, if you chose the Latest version of an SSM document when you created an association and you edit the association by choosing a different document version on the Documents page, State Manager applies the association at the next specified cron interval if you previously set ApplyOnlyAtCronInterval to true. If this option wasn't selected, State Manager immediately runs the association.

For more information, see Understanding when associations are applied to resources and About target updates with Automation runbooks in the Amazon Web Services Systems Manager User Guide.

This parameter isn't supported for rate expressions.

You can reset this parameter. To do so, specify the no-apply-only-at-cron-interval parameter when you update the association from the command line. This parameter forces the association to run immediately after updating it and according to the interval specified.
