1、docker trust sign 简介

docker trust sign 命令用于对 Docker 镜像进行签名的命令。它使用已配置的密钥对镜像进行签名，以验证镜像的完整性和来源可信性。

Docker trust sign为标签添加签名，以创建签名仓库。

参考文档：https://docs.docker.com/engine/reference/commandline/trust_sign/

2、docker trust sign 语法

docker trust sign IMAGE:TAG

3、docker trust revoke 命令

1）作为仓库管理员签署一个标签

给定一个镜像:

docker trust inspect --pretty example/trust-demo

SIGNED TAG          DIGEST                                                             SIGNERS

Administrative keys for example/trust-demo:
Repository Key: 36d4c3601102fa7c5712a343c03b94469e5835fb27c191b529c06fd19c14a942

使用 docker trust sign 对一个新的标签进行签署:

docker trust sign example/trust-demo:v2
