## Description
|
|
|
|
`docker trust signer remove` removes signers from signed repositories.
|
|
|
|
## Examples
|
|
|
|
### Remove a signer from a repo
|
|
|
|
To remove an existing signer, `alice`, from this repository:
|
|
|
|
```console
|
|
$ docker trust inspect --pretty example/trust-demo
|
|
|
|
No signatures for example/trust-demo
|
|
|
|
|
|
List of signers and their keys:
|
|
|
|
SIGNER KEYS
|
|
alice 05e87edcaecb
|
|
bob 5600f5ab76a2
|
|
|
|
Administrative keys for example/trust-demo:
|
|
Repository Key: ecc457614c9fc399da523a5f4e24fe306a0a6ee1cc79a10e4555b3c6ab02f71e
|
|
Root Key: 3cb2228f6561e58f46dbc4cda4fcaff9d5ef22e865a94636f82450d1d2234949
|
|
```
|
|
|
|
Remove `alice` with `docker trust signer remove`:
|
|
|
|
```console
|
|
$ docker trust signer remove alice example/trust-demo
|
|
|
|
Removing signer "alice" from image example/trust-demo...
|
|
Enter passphrase for repository key with ID 642692c:
|
|
Successfully removed alice from example/trust-demo
|
|
```
|
|
|
|
`docker trust inspect --pretty` now does not list `alice` as a valid signer:
|
|
|
|
```console
|
|
$ docker trust inspect --pretty example/trust-demo
|
|
|
|
No signatures for example/trust-demo
|
|

```
|
|
|
|
### Remove a signer from multiple repos

|
|
|
To remove an existing signer, `alice`, from multiple repositories:
|
|
|
|
```console
|
|
$ docker trust inspect --pretty example/trust-demo
|

```
|
|
|
|
Remove `alice` from both images with a single `docker trust signer remove` command:
|
|
|
|
```console
|
|
$ docker trust signer remove alice example/trust-demo example/trust-demo2
|
|
|
|
Removing signer "alice" from image example/trust-demo...
|
|
Enter passphrase for repository key with ID 95b9e55:
|
|
Successfully removed alice from example/trust-demo
|
|
|
|
Removing signer "alice" from image example/trust-demo2...
|
|
Enter passphrase for repository key with ID ece554f:
|
|
Successfully removed alice from example/trust-demo2
|
|
```
|
|
|
|
Run `docker trust inspect --pretty` to confirm that `alice` is no longer listed as a valid
|
|
signer of either `example/trust-demo` or `example/trust-demo2`:
|
|
|
|
```console
|
|
$ docker trust inspect --pretty example/trust-demo

|
|
|
|
`docker trust signer remove` removes signers to repositories on a best effort
|
|
basis, so it will continue to remove the signer from subsequent repositories if
|
|
one attempt fails:
|
|
|
|
```console
|
|
$ docker trust signer remove alice example/unauthorized example/authorized
|
|
|
|
Removing signer "alice" from image example/unauthorized...
|
|

|
|
|
|

|
|
Enter passphrase for repository key with ID c6772a0:
|
|
Successfully removed alice from example/authorized
|
|
|
|

|
|
```
