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 ``` ## Related commands * [config create](config_create.md) * [config ls](config_ls.md) * [config rm](config_rm.md)
