Attached and Detached Job Instances

By default, each job instance is attached to the parent job template. When attached to the parent job template, the following statements are true:

Edits to the parent job template are applied to attached job instances

When you edit the parent job template, Control Hub applies the same updates to all attached job instances. If any attached job instances are currently running, then Control Hub restarts those instances to apply the updates to them.

For details about how Control Hub handles edits to parameter values in the job template, see Updating Job Template Parameters.

Attached job instances display in the parent job template's run history

When you view the details of the parent job template, Control Hub displays all currently running attached job instances in the Running Job Instances section and displays the run history of all attached job instances in the Run History section.

Attached job instances cannot be edited

You cannot directly edit attached job instances.

When you create a job instance, you can optionally detach the job instance from the parent job template. Detached job instances are not updated when the parent job template is edited, do not display in the parent job template details, and can be directly edited. Create a detached job instance when you want to use the job details and default parameter values defined in the job template, but don't want subsequent changes to the job template to be applied to the job instance. Instead, you want to be able to directly edit the detached job instance.

To detach a job instance, clear the Attach Instance to Template advanced option when you create the job instance.
