# Command: node pool apply
|
|
|
|
|
|
|
|
The `node pool apply` command is used to create or update a node pool.
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
```plaintext
|
|
|
|
nomad node pool apply [options] <input>
|
|
|
|
```
|
|
|
|
|
|
|
|
Apply is used to create or update a node pool. The specification file is read
|
|
|
|
from stdin by specifying `-`, otherwise a path to the file is expected.
|
|
|
|
|
|
|
|
If ACLs are enabled, this command requires a token with the `write` capability

|
|
|
in a `node_pool` policy that matches the node pool being targeted. In federated
|
|
|
|
clusters, the node pool will be created in the authoritative region and will be
|
|
|
|
replicated to all federated regions.

|
|
|
|
|
|

$ cat <<EOF | nomad node pool apply -
|
|
|
|

|
|
|
description = "Node pool for dev workloads."
