## 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"
    }
  }
]
```

### Format the output (--format) {#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
