Nomad
Command: deployment unblock
The deployment unblock command is used to manually mark a blocked
multiregion deployment as successful. A blocked deployment is a multiregion
deployment within a region that has completed within a region but is waiting
on the other federated regions. The deployment unblock command can be used
in cases where a failed peer region is unable to communicate its failed
deployment status to other regions to force a deployment to complete.
Usage
nomad deployment unblock [options] <deployment id>
The deployment unblock command requires a single argument, a deployment ID or
prefix.
When ACLs are enabled, this command requires a token with the submit-job
and read-job capabilities for the deployment's namespace.
