Usage: nomad deployment unblock [options] <deployment id>
Unblock is used to unblock a multiregion deployment that's waiting for
peer region deployments to complete.
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) + `
Unblock Options:
-detach
Return immediately instead of entering monitor mode. After deployment
unblock, 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.
