[!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 in the documentation.
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" } } } ]
You can use the --format
option to obtain specific information about a secret. The following example command outputs the creation time of the secret.
$ docker secret inspect --format='{{.CreatedAt}}' eo7jnzguqgtpdah3cm5srfb97 2017-03-24 08:15:09.735271783 +0000 UTC
