# trust sign
```markdown
Usage: docker trust sign [OPTIONS] IMAGE:TAG
Sign an image

```
## Description
`docker trust sign` adds signatures to tags to create signed repositories.
## Examples
### Sign a tag as a repo admin
Given an image:
```console
$ docker trust inspect --pretty example/trust-demo
SIGNED TAG DIGEST SIGNERS
v1 c24134c079c35e698060beabe110bb83ab285d0d978de7d92fed2c8c83570a41 (Repo Admin)
Administrative keys for example/trust-demo:
Repository Key: 36d4c3601102fa7c5712a343c03b94469e5835fb27c191b529c06fd19c14a942

```
Sign a new tag with `docker trust sign`:
```console
$ docker trust sign example/trust-demo:v2
Signing and pushing trust metadata for example/trust-demo:v2
The push refers to a repository [docker.io/example/trust-demo]

Signing and pushing trust metadata
Enter passphrase for repository key with ID 36d4c36:

```
Use `docker trust inspect --pretty` to list the new signature:
```console
$ docker trust inspect --pretty example/trust-demo

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

## Initialize a new repo and sign a tag
When signing an image on a repo for the first time, `docker trust sign` sets up new keys before signing the image.
```console
$ docker trust inspect --pretty example/trust-demo
No signatures or cannot access example/trust-demo
```
```console
$ docker trust sign example/trust-demo:v1
Signing and pushing trust metadata for example/trust-demo:v1
Enter passphrase for root key with ID 36cac18:
Enter passphrase for new repository key with ID 731396b:
Repeat passphrase for new repository key with ID 731396b:
Enter passphrase for new alice key with ID 6d52b29:
Repeat passphrase for new alice key with ID 6d52b29:
Created signer: alice
