码头工人信任检查

描述

返回有关密钥和签名的低级信息

用法

$ docker trust inspect IMAGE[:TAG] [IMAGE[:TAG]...]

扩展说明

docker trust inspect提供有关签名存储库的低级JSON信息。这包括所有已签名的图像标签，签名者以及可以签名新标签的人。

有关此命令的示例用法，请参阅下面的示例部分。

选项

名称，简写 默认 描述
--pretty 以人类友好的格式打印信息

例子

获取有关单个图像标签签名的底层详细信息

使用docker trust inspect获取有关图像的信任信息。以下示例为alpine:latest图像打印信任信息：

$ docker trust inspect alpine:latest

输出为JSON格式，例如：

[
  {
    "Name": "alpine:latest",
    "SignedTags": [
      {
        "SignedTag": "latest",
        "Digest": "d6bfc3baf615dc9618209a8d607ba2a8103d9c8a405b3bd8741d88b4bef36478",
        "Signers": [
          "Repo Admin"
        ]
      }
    ],
    "Signers": [],
    "AdministrativeKeys": [
      {
        "Name": "Repository",
        "Keys": [
            {
                "ID": "5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd"
            }
        ]
      },
      {
        "Name": "Root",
        "Keys": [
            {
                "ID": "a2489bcac7a79aa67b19b96c4a3bf0c675ffdf00c6d2fabe1a5df1115e80adce"
            }
        ]
      }
    ]
  }
]

该SignedTags键将列出SignedTag名称，Digest以及Signers负责签名。

AdministrativeKeys将列出Repository和Root键。

如果通过其他docker trust 命令为存储库设置了签名者，请docker trust inspect包括一个Signers密钥：

$ docker trust inspect my-image:purple

输出为JSON格式，例如：

[
  {
    "Name": "my-image:purple",
    "SignedTags": [
      {
        "SignedTag": "purple",
        "Digest": "941d3dba358621ce3c41ef67b47cf80f701ff80cdf46b5cc86587eaebfe45557",
        "Signers": [
          "alice",
          "bob",
          "carol"
        ]
      }
    ],
    "Signers": [
      {
        "Name": "alice",
        "Keys": [
            {
                "ID": "04dd031411ed671ae1e12f47ddc8646d98f135090b01e54c3561e843084484a3"
            },
            {
                "ID": "6a11e4898a4014d400332ab0e096308c844584ff70943cdd1d6628d577f45fd8"
            }
        ]
      },
      {
        "Name": "bob",
        "Keys": [
            {
                "ID": "433e245c656ae9733cdcc504bfa560f90950104442c4528c9616daa45824ccba"
            }
        ]
      },
      {
        "Name": "carol",
        "Keys": [
            {
                "ID": "d32fa8b5ca08273a2880f455fcb318da3dc80aeae1a30610815140deef8f30d9"
            },
            {
                "ID": "9a8bbec6ba2af88a5fad6047d428d17e6d05dbdd03d15b4fc8a9a0e8049cd606"
            }
        ]
      }
    ],
    "AdministrativeKeys": [
      {
        "Name": "Repository",
        "Keys": [
            {
                "ID": "27df2c8187e7543345c2e0bf3a1262e0bc63a72754e9a7395eac3f747ec23a44"
            }
        ]
      },
      {
        "Name": "Root",
        "Keys": [
            {
                "ID": "40b66ccc8b176be8c7d365a17f3e046d1c3494e053dd57cfeacfe2e19c4f8e8f"
            }
        ]
      }
    ]
  }
]

如果图像标签未签名或不可用，docker trust inspect则不显示任何已签名标签。

$ docker trust inspect unsigned-img

No signatures or cannot access unsigned-img

但是，如果在同一图像存储库中签署了其他标签，则会 docker trust inspect报告相关的关键信息：

$ docker trust inspect alpine:unsigned

输出为JSON格式，例如：

[
  {
    "Name": "alpine:unsigned",
    "Signers": [],
    "AdministrativeKeys": [
      {
        "Name": "Repository",
        "Keys": [
          {
            "ID": "5a46c9aaa82ff150bb7305a2d17d0c521c2d784246807b2dc611f436a69041fd"
          }
        ]
      },
      {
        "Name": "Root",
        "Keys": [
          {
            "ID": "a2489bcac7a79aa67b19b96c4a3bf0c675ffdf00c6d2fabe1a5df1115e80adce"
          }
        ]
      }
    ]
  }
]

获取有关存储库中所有图像标签的签名的详细信息

如果未指定标签，docker trust inspect将报告存储库中所有已签名标签的详细信息：

$ docker trust inspect alpine

输出为JSON格式，例如：

[
  {
    "Name": "alpine",
    "SignedTags": [
      {
        "SignedTag": "3.5",
        "Digest": "b007a354427e1880de9cdba533e8e57382b7f2853a68a478a17d447b302c219c",
        "Signers": [

        ]
      }
    ],
    "Signers": [],

          }
        ]
      }
    ]
  }
]

获取有关多个图像签名的详细信息

docker trust inspect 可以将多个存储库和图像作为参数，并以有序列表的形式报告结果：

$ docker trust inspect alpine notary

输出为JSON格式，例如：

格式设定

您可以使用以下--pretty选项，以人类可读的格式而不是默认的JSON输出来打印检查输出：

获取有关单个图像标签的签名的详细信息

$ docker trust inspect --pretty alpine:latest

SIGNED TAG          DIGEST                                                             SIGNERS

该SIGNED TAG是一个独特的内容寻址签名的图像标签 DIGEST。SIGNERS列出所有已签名的实体。

列出的管理密钥指定了信任的根密钥以及管理存储库密钥。这些密钥负责修改签名者，并旋转已签名存储库的密钥。

如果通过其他docker trust命令 为存储库设置了签名者，则将docker trust inspect --pretty其适当地显示为aSIGNER 并指定其KEYS：

$ docker trust inspect --pretty my-image:purple

但是，如果其他标签在同一图像存储库中签名，则会 docker trust inspect报告相关的密钥信息。

$ docker trust inspect --pretty alpine:unsigned
