Usage: nomad job dispatch [options] <constructor> [input source]
|
|
|
|
Dispatch creates an instance of a constructor job. A data payload to the
|
|
dispatched instance can be provided via stdin by using "-" or by specifiying a
|
|
path to a file. Metadata can be supplied by using the meta flag one or more
|
|
times.
|
|
|
|
Upon successfully creation, the dispatched job ID will be printed and the
|
|
triggered evaluation will be monitored. This can be disabled by supplying the
|
|
detach flag.
|
|
|
|
General Options:
|
|
|
|
` + generalOptionsUsage() + `
|
|
|
|
Dispatch Options:
|
|
|
|
-detach
|
|
Return immediately instead of entering monitor mode. After job dispatch,
|
|
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.
