Examples

Inspect a secret by name or ID

You can inspect a secret, either by its name, or ID

For example, given the following secret:

$ docker secret ls

ID                          NAME                CREATED             UPDATED
eo7jnzguqgtpdah3cm5srfb97   my_secret           3 minutes ago       3 minutes ago
$ docker secret inspect secret.json

The output is in JSON format, for example:

[
  {
    "ID": "eo7jnzguqgtpdah3cm5srfb97",
    "Version": {
      "Index": 17
    },
    "CreatedAt": "2017-03-24T08:15:09.735271783Z",
    "UpdatedAt": "2017-03-24T08:15:09.735271783Z",
    "Spec": {
      "Name": "my_secret",
      "Labels": {
        "env": "dev",
        "rev": "20170324"
      }
    }
  }
]
