Command: deployment promote
The deployment promote command 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
job revert command.
Usage
The deployment promote command requires a single argument, a deployment ID or
prefix. When run without specifying any groups to promote, the promote command
promotes all task groups. The group flag can be specified multiple times to
select particular groups to promote.
When ACLs are enabled, this command requires a token with the submit-job
and read-job capabilities for the deployment's namespace.

-address=<addr>: The address of the Nomad server. Overrides theNOMAD_ADDRenvironment variable if set. Defaults tohttp://127.0.0.1:4646.-region=<region>: The region of the Nomad server to forward commands to. Overrides theNOMAD_REGIONenvironment variable if set. Defaults to the Agent's local region.-namespace=<namespace>: The target namespace for queries and actions bound to a namespace. Overrides theNOMAD_NAMESPACEenvironment variable if set. If set to'*', subcommands which support this functionality query all namespaces authorized to user. Defaults to the "default" namespace.-no-color: Disables colored command output. Alternatively,NOMAD_CLI_NO_COLORmay be set. This option takes precedence over-force-color.-force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively,NOMAD_CLI_FORCE_COLORmay be set. This option has no effect if-no-coloris also used.-ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides theNOMAD_CACERTenvironment variable if set.-ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both-ca-certand-ca-pathare specified,-ca-certis used.
