## Description
|
|
|
|
Returns information about a node. By default, this command renders all results
|
|
in a JSON array. You can specify an alternate format to execute a
|
|
given template for each result. Go's
|
|
[text/template](https://pkg.go.dev/text/template) package describes all the
|
|
details of the format.
|
|
|
|
> **Note**
|
|
>
|
|
> This is a cluster management command, and must be executed on a swarm
|
|
> manager node. To learn about managers and workers, refer to the
|
|
> [Swarm mode section](https://docs.docker.com/engine/swarm/) in the
|
|
> documentation.
