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.
|
|
|
|
When ACLs are enabled, this command requires a token with the 'submit-job'
|
|
and 'read-job' capabilities for the deployment's namespace.
|
|
|
|
General Options:
|
|
|
|
` + generalOptionsUsage(usageOptsDefault) + `
|
|
|
|
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.
