Usage: nomad deployment pause [options] <deployment id>

Pause is used to pause a deployment. Pausing a deployment will pause the

placement of new allocations as part of rolling deployment.
|
|
|
|
When ACLs are enabled, this command requires a token with the 'submit-job'
|
|
and 'read-job' capabilities for the deployment's namespace.

General Options:

Pause Options:
