Usage: nomad deployment fail [options] <deployment id>
Fail is used to mark a deployment as failed. Failing a deployment will
stop the placement of new allocations as part of rolling deployment and
if the job is configured to auto revert, the job will attempt to roll back to a
stable version.
General Options:
` + generalOptionsUsage() + `
Fail Options:
-detach
Return immediately instead of entering monitor mode. After deployment
resume, the evaluation ID will be printed to the screen, which can be used
to examine the evaluation using the eval-status command.
-verbose
Display full information.
