This includes all image tags that are signed, who signed them, and who can sign new tags. By default, `docker trust view` renders results in a table. `docker trust view` is currently experimental. ## Examples ### Get details about signatures for a single image tag ```bash $ docker trust view alpine:latest SIGNED TAG DIGEST SIGNERS latest 1072e499f3f655a032e88542330cf75b02e7bdf673278f701d7ba61629ee3ebe (Repo Admin) Administrative keys for alpine:latest: Repository Key: 5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd Root Key: a2489bcac7a79aa67b19b96c4a3bf0c675ffdf00c6d2fabe1a5df1115e80adce ``` The `SIGNED TAG` is the signed image tag with a unique content-addressable `DIGEST`. `SIGNERS` lists all entities who have signed. The administrative keys listed specify the root key of trust, as well as the administrative repository key. These keys are responsible for modifying signers, and rotating keys for the signed repository. If signers are set up for the repository via other `docker trust` commands, `docker trust view` displays them appropriately as a `SIGNER` and specify their `KEYS`: ```bash $ docker trust view my-image:purple SIGNED TAG DIGEST SIGNERS purple 941d3dba358621ce3c41ef67b47cf80f701ff80cdf46b5cc86587eaebfe45557 alice, bob, carol List of signers and their keys: SIGNER KEYS alice 47caae5b3e61, a85aab9d20a4 bob 034370bcbd77, 82a66673242c carol b6f9f8e1aab0 Administrative keys for my-image: Repository Key: 27df2c8187e7543345c2e0bf3a1262e0bc63a72754e9a7395eac3f747ec23a44 Root Key: 40b66ccc8b176be8c7d365a17f3e046d1c3494e053dd57cfeacfe2e19c4f8e8f ``` If the image tag is unsigned or unavailable, `docker trust view` does not display any signed tags. ```bash $ docker trust view unsigned-img No signatures or cannot access unsigned-img ``` However, if other tags are signed in the same image repository, `docker trust view` reports relevant key information. ```bash $ docker trust view alpine:unsigned No signatures for alpine:unsigned Administrative keys for alpine:unsigned: Repository Key: 5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd Root Key: a2489bcac7a79aa67b19b96c4a3bf0c675ffdf00c6d2fabe1a5df1115e80adce ``` ### Get details about signatures for all image tags in a repository ```bash $ docker trust view alpine SIGNED TAG DIGEST SIGNERS 2.6 9ace551613070689a12857d62c30ef0daa9a376107ec0fff0e34786cedb3399b (Repo Admin) 2.7 9f08005dff552038f0ad2f46b8e65ff3d25641747d3912e3ea8da6785046561a (Repo Admin) 3.1 d9477888b78e8c6392e0be8b2e73f8c67e2894ff9d4b8e467d1488fcceec21c8 (Repo Admin) 3.2 19826d59171c2eb7e90ce52bfd822993bef6a6fe3ae6bb4a49f8c1d0a01e99c7 (Repo Admin) 3.3 8fd4b76819e1e5baac82bd0a3d03abfe3906e034cc5ee32100d12aaaf3956dc7 (Repo Admin) 3.4 833ad81ace8277324f3ca8c91c02bdcf1d13988d8ecf8a3f97ecdd69d0390ce9 (Repo Admin) 3.5 af2a5bd2f8de8fc1ecabf1c76611cdc6a5f1ada1a2bdd7d3816e121b70300308 (Repo Admin) 3.6 1072e499f3f655a032e88542330cf75b02e7bdf673278f701d7ba61629ee3ebe (Repo Admin) edge 79d50d15bd7ea48ea00cf3dd343b0e740c1afaa8e899bee475236ef338e1b53b (Repo Admin) latest 1072e499f3f655a032e88542330cf75b02e7bdf673278f701d7ba61629ee3ebe (Repo Admin) Administrative keys for alpine: Repository Key: 5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd Root Key: a2489bcac7a79aa67b19b96c4a3bf0c675ffdf00c6d2fabe1a5df1115e80adce ``` Here's an example with signers that are set up by `docker trust` commands: ```bash $ docker trust view my-image SIGNED TAG DIGEST SIGNERS red 852cc04935f930a857b630edc4ed6131e91b22073bcc216698842e44f64d2943 alice blue f1c38dbaeeb473c36716f6494d803fbfbe9d8a76916f7c0093f227821e378197 alice, bob green cae8fedc840f90c8057e1c24637d11865743ab1e61a972c1c9da06ec2de9a139 alice, bob yellow 9cc65fc3126790e683d1b92f307a71f48f75fa7dd47a7b03145a123eaf0b45ba carol purple 941d3dba358621ce3c41ef67b47cf80f701ff80cdf46b5cc86587eaebfe45557 alice, bob, carol orange d6c271baa6d271bcc24ef1cbd65abf39123c17d2e83455bdab545a1a9093fc1c alice List of signers and their keys for my-image: SIGNER KEYS alice 47caae5b3e61, a85aab9d20a4 bob 034370bcbd77, 82a66673242c carol b6f9f8e1aab0 Administrative keys for my-image: Repository Key: 27df2c8187e7543345c2e0bf3a1262e0bc63a72754e9a7395eac3f747ec23a44 Root Key: 40b66ccc8b176be8c7d365a17f3e046d1c3494e053dd57cfeacfe2e19c4f8e8f ```
