Usage: nomad job eval [options] <job_id>
|
|
|
|
Force an evaluation of the provided job ID. Forcing an evaluation will trigger the scheduler
|
|
to re-evaluate the job. The force flags allow operators to force the scheduler to create
|
|
new allocations under certain scenarios.

General Options:

Eval Options:
|
|
|
|
-force-reschedule
|
|
Force reschedule failed allocations even if they are not currently
|
|
eligible for rescheduling.
|
|
|
|
-detach
|
|
Return immediately instead of entering monitor mode. The ID
|
|
of the evaluation created will be printed to the screen, which can be
|
|
used to examine the evaluation using the eval-status command.
|

|
|
-verbose

Display full information.
