Here’s an example of a repo with two signed tags:
$ docker trust view example/trust-demo
SIGNED TAG DIGEST SIGNERS
red 852cc04935f930a857b630edc4ed6131e91b22073bcc216698842e44f64d2943 alice
blue f1c38dbaeeb473c36716f6494d803fbfbe9d8a76916f7c0093f227821e378197 alice, bob
List of signers and their keys for example/trust-demo:
SIGNER KEYS
alice 05e87edcaecb
bob 5600f5ab76a2
Administrative keys for example/trust-demo:
Repository Key: ecc457614c9fc399da523a5f4e24fe306a0a6ee1cc79a10e4555b3c6ab02f71e
Root Key: 3cb2228f6561e58f46dbc4cda4fcaff9d5ef22e865a94636f82450d1d2234949
When alice, one of the signers, runs docker trust revoke:
$ docker trust revoke example/trust-demo:red
Enter passphrase for delegation key with ID 27d42a8:
Successfully deleted signature for example/trust-demo:red
After revocation, the tag is removed from the list of released tags:
$ docker trust view example/trust-demo
