Usage: nomad job promote [options] <job id>
|
|
|
|
Promote is used to promote task groups in the most recent deployment for the
|
|
given job. Promotion should occur when the deployment has placed canaries for a
|
|
task group and those canaries have been deemed healthy. When a task group is
|
|
promoted, the rolling upgrade of the remaining allocations is unblocked. If the
|
|
canaries are found to be unhealthy, the deployment may either be failed using
|
|
the "nomad deployment fail" command, the job can be failed forward by submitting
|
|
a new version or failed backwards by reverting to an older version using the
|
|
"nomad job revert" command.
|
|
|
|
General Options:
|
|
|
|
` + generalOptionsUsage() + `
|
|
|
|
Promote Options:
|
|
|
|
-group
|
|
Group may be specified many times and is used to promote that particular
|
|
group. If no specific groups are specified, all groups are promoted.
|
|
|
|
-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.
