# nomad node meta reference
|
|
|
|
The `meta` command is used to read and update node metadata. This metadata is
|
|
available for [interpolation using the `${meta.<key>}` syntax in jobs][interp].
|
|
|
|
## Usage
|
|
|
|
```plaintext
|
|
nomad node meta <subcommand> [options]
|
|
```
|
|
|
|
The `apply` subcommand allows for dynamically updating node metadata. The
|
|
`read` subcommand allows reading all of the metadata set on the client. All
|
|
commands interact directly with a client and allow setting a custom target with
|
|
the `-node-id` option.
|
|
|
|
Please see the individual subcommand help for detailed usage information:
|
|
|
|
- [`apply`][apply] - Modify node metadata
|
|
- [`read`][read] - Read node metadata
