Usage: nomad deployment promote [options] <deployment id>
|
|
|
|
Promote is used to promote task groups in a deployment. 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:
|
|
|
|
-all
|
|
All promotes all task groups in the deployment.
|
|
|
|
-group
|
|
Group may be specified many times and is used to promote that particular
|
|
group.
|
|
|
|
-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.
