# `nomad node pool apply` command reference
|
|
|
|
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.
|
|
|
|
## General options
|
|
|
|
@include 'general_options_no_namespace.mdx'
|
|
|
|
## Apply options
|
|
|
|
- `-json`: Parse the input as a JSON node pool specification.
|
|
|
|
## Examples
|
|
|
|
Create a node pool from a file:
|
|
|
|
```hcl
|
|
# prod_pool.nomad.hcl
|
|
node_pool "prod" {
|
|
description = "Node pool for production workloads."
|
|
|
|
meta {
|
|
env = "prod"
|
|
}
|
|
|
|
# Available only in Nomad Enterprise.
|
|
scheduler_config {
|
|
scheduler_algorithm = "spread"
|
|
}
|
|
}
|
|
```
|
|
|
|
```shell-session
|
|
$ nomad node pool apply prod_pool.nomad.hcl
|
|
Successfully applied node pool "prod"!
|
|
```
|
|
|
|
Create a node pool from stdin:
|
|
|
|
```shell-session
|
|
$ cat prod_pool.nomad.hcl | nomad node pool apply -
|
|
Successfully applied node pool "prod"!
|
|
```
|
|
|
|
```shell-session
|
|
$ cat <<EOF | nomad node pool apply -
|
|
node_pool "dev" {
|
|
description = "Node pool for dev workloads."
|
|
}
|
|
EOF
|
|
Successfully applied node pool "dev"!
|
|
```
