Usage: nomad job allocs [options] <job>
|
|
|
|
Display allocations for a particular job.
|
|
|
|
When ACLs are enabled, this command requires a token with the 'read-job'
|
|
capability for the job's namespace. The 'list-jobs' capability is required to
|
|
run the command with a job prefix instead of the exact job ID.

General Options:

|
|
|
` + generalOptionsUsage(usageOptsDefault) + `
|
|
|
|
Allocs Options:
|
|
|
|
-all
|
|
Display all allocations matching the job ID, even those from an older
|
|
instance of the job.
|
|
|
|
-json
|
|
Output the allocations in a JSON format.
|
|
|
|
-t
|
|
Format and display allocations using a Go template.

-verbose
|
|
Display full information.
