# config inspect
```Markdown
Usage: docker config inspect [OPTIONS] CONFIG [CONFIG...]
Display detailed information on one or more configs
Options:
-f, --format string Format the output using the given Go template
--help Print usage
```
## Description
Inspects the specified config.
By default, this renders all results in a JSON array. If a format is specified,
the given template will be executed for each result.
Go's [text/template](https://golang.org/pkg/text/template/) package
describes all the details of the format.
For detailed information about using configs, refer to [store configuration data using Docker Configs](https://docs.docker.com/engine/swarm/configs/).
> **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.
## Examples
### Inspect a config by name or ID
You can inspect a config, either by its *name*, or *ID*
For example, given the following config:
```console
$ docker config ls
ID NAME CREATED UPDATED
eo7jnzguqgtpdah3cm5srfb97 my_config 3 minutes ago 3 minutes ago
```
```console
$ docker config inspect config.json
```
The output is in JSON format, for example:
```json
[
{
"ID": "eo7jnzguqgtpdah3cm5srfb97",
"Version": {
"Index": 17
},
"CreatedAt": "2017-03-24T08:15:09.735271783Z",
"UpdatedAt": "2017-03-24T08:15:09.735271783Z",
"Spec": {
"Name": "my_config",
"Labels": {
"env": "dev",
"rev": "20170324"
},
"Data": "aGVsbG8K"
}
}
]
```
### <a name="format"></a> Format the output (--format)
You can use the --format option to obtain specific information about a
config. The following example command outputs the creation time of the
config.
```console
$ docker config inspect --format='{{.CreatedAt}}' eo7jnzguqgtpdah3cm5srfb97
2017-03-24 08:15:09.735271783 +0000 UTC
```
