Resource Quota Specification

Resource Quotas enable you to limit resource consumption across teams or projects to reduce waste and align budgets.

You can manage quotas using the Nomad CLI via the quota subcommands, or with Nomad's Quota HTTP API directly.

You may also follow a Quotas tutorial for more example usage.

Example quota specification

The CLI command nomad quota init generates an example spec.hcl file.

name        = "default-quota"description = "Limit the shared default namespace" # Create a limit for the global region. Additional limits may# be specified in-order to limit other regions.limit {  region = "global"  region_limit {    cores      = 0    cpu        = 2500    memory     = 1000    memory_max = 1000    device "nvidia/gpu/1080ti" {      count = 1    }  }  variables_limit = 1000}

Quota specification parameters

• name (string) - The name of the Quota. Nomad uses name to connect the quota a Namespace.
• description (string: <optional>) - A human-readable description.
• limit (QuotaLimit) - The resource limit in a Nomad region.

limit parameters

• region (string) - The Nomad region that the limit applies to.
• region_limit (RegionLimit) - Resources to limit.
• variables_limit (int: 0) - Maximum total size of all Nomad variables in MiB. The default 0 means unlimited, and -1 means variables are fully disabled.

region_limit parameters

Region limits define the limits on cumulative task resources blocks for allocations in the namespace and region the quota is applied to.

• cores (int: <optional>) - The limit on total number of CPU cores from all resources.cores in the namespace. The CPU concepts documentation has more details on CPU resources.
• cpu (int: <optional>) - The limit on total amount of CPU from all resources.cpu in the namespace.
• memory (int: <optional>) - The limit on total mount of memory in MB from all resources.memory in the namespace.
• memory_max (int: <optional>) - The limit on total mount of hard memory limits in MB from all resources.memory_max in the namespace.
• device (Device: nil)

device parameters

The device label specifies which device(s) the quota applies to, equivalent to the device block in a job specification.

• count (int) - How many of this device may be used.
