Usage: nomad deployment <subcommand> [options] [args]

  This command groups subcommands for interacting with deployments. Deployments
  are used to manage a transistion between two versions of a Nomad job. Users
  can inspect an ongoing deployment, promote canary allocations, force fail
  deployments, and more.

  Examine a deployments status:

      $ nomad deployment status <deployment-id>

  Promote the canaries to allow the remaining allocations to be updated in a
  rolling deployment fashion:

      $ nomad deployment promote <depoloyment-id>

  Mark a deployment as failed. This will stop new allocations from being placed
  and if the job's upgrade stanza specifies auto_revert, causes the job to
  revert back to the last stable version of the job:

      $ nomad deployment fail <depoloyment-id>

  Please see the individual subcommand help for detailed usage information.
