Revoke signatures from a signed tag

Here’s an example of a repo with two signed tags:

$ docker trust inspect --pretty 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:

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 inspect --pretty example/trust-demo
SIGNED TAG          DIGEST                                                              SIGNERS

Revoke signatures on all tags in a repository

When no tag is specified, docker trust revokes all signatures that you have a signing key for.

$ docker trust inspect --pretty example/trust-demo
SIGNED TAG          DIGEST                                                              SIGNERS
red                 852cc04935f930a857b630edc4ed6131e91b22073bcc216698842e44f64d2943    alice

$ docker trust inspect --pretty example/trust-demo
