docker manifest 描述

管理 Docker 映像清单和清单列表

需要连接网络，从docker hub上拉取信息，关于manifest信息 打印出来。不连接网络会报错。

‎注意：此命令在 Docker 客户端上是实验性的。‎
‎它不应在生产环境中使用。‎

官方文档地址：https://docs.docker.com/engine/reference/commandline/manifest/

我的理解：

docker hub社区的镜像维护，让他人直观的了解你构建的镜像。

就是 docker image inspect <image ID> 查看镜像的信息，是否符合你的使用，里面的CPU架构版本，安装程序，依赖库，网络等信息。用来维护docker hub社区中的镜像信息，让别可以更加直观的了解内容。

使用

$ docker manifest COMMAND COMMAND

‎扩展描述‎

‎该命令本身不执行任何操作。为了对清单或清单列表进行操作，必须使用其中一个子命令。‎docker manifest

‎单个清单是有关图像的信息，例如图层、大小和摘要。docker 清单命令还为用户提供了其他信息，例如构建映像的 os 和体系结构。‎

‎清单列表是通过指定一个或多个（理想情况下是多个）图像名称创建的映像层的列表。然后，可以将其用作 与 中的映像名称 和 命令相同的方式。‎docker pull docker run

‎理想情况下，清单列表是从功能相同的图像创建的，用于不同的os/arch组合。因此，清单列表通常称为"多架构映像"。但是，用户可以创建一个指向两个映像的清单列表 - 一个用于 amd64 上的 Windows，另一个用于 amd64 上的 darwin。‎

$ docker manifest

Usage:  docker manifest COMMAND

The **docker manifest** command has subcommands for managing image manifests and
manifest lists. A manifest list allows you to use one name to refer to the same image
built for multiple architectures.

To see help for a subcommand, use:

    docker manifest CMD --help

For full details on using docker manifest lists, see the registry v2 specification.

EXPERIMENTAL:
  docker manifest is an experimental feature.
  Experimental features provide early access to product functionality. These
  features may change between releases without warning, or can be removed from a
  future release. Learn more about experimental features in our documentation:
  https://docs.docker.com/go/experimental/

Commands:
  annotate    Add additional information to a local image manifest
  create      Create a local manifest list for annotating and pushing to a registry
  inspect     Display an image manifest, or manifest list
  push        Push a manifest list to a repository
  rm          Delete one or more manifest lists from local storage

Run 'docker manifest COMMAND --help' for more information on a command.

manifest inspect 清单检查

$ docker manifest inspect --help

Usage:  docker manifest inspect [OPTIONS] [MANIFEST_LIST] MANIFEST

Display an image manifest, or manifest list

Options:
      --insecure   Allow communication with an insecure registry
  -v, --verbose    Output additional info including layers and platform

manifest create 清单创建

$ docker manifest create --help

Usage:  docker manifest create MANIFEST_LIST MANIFEST [MANIFEST...]

Create a local manifest list for annotating and pushing to a registry

Options:
  -a, --amend      Amend an existing manifest list
      --insecure   Allow communication with an insecure registry

manifest annotate 清单注释

$ docker manifest annotate --help

Usage:  docker manifest annotate [OPTIONS] MANIFEST_LIST MANIFEST

Add additional information to a local image manifest

Options:
      --arch string           Set architecture
      --os string             Set operating system
      --os-features strings   Set operating system feature
      --os-version string     Set operating system version
      --variant string        Set architecture variant

manifest push 清单推送

$ docker manifest push --help

Usage:  docker manifest push [OPTIONS] MANIFEST_LIST

Push a manifest list to a repository

Options:
      --insecure   Allow push to an insecure registry
  -p, --purge      Remove the local manifest list after push

使用不安全的注册表

manifest 命令仅与 Docker 注册表交互。因此，它无法向引擎查询允许的不安全注册表列表。为了允许 CLI 与不安全的注册表交互，一些docker manifest 命令有一个--insecure标志。对于查询注册表的每个事务，例如 create，--insecure必须指定标志。此标志告诉 CLI，此注册表调用可能会忽略丢失或自签名证书等安全问题。同样，在manifest push不安全的注册表上，--insecure必须指定标志。如果这不与不安全的注册表一起使用，则清单命令将无法找到满足默认要求的注册表。

示例

创建并推送清单列表

要创建清单列表，首先create通过指定要包含在清单列表中的组成图像在本地创建清单列表。请记住，这是推送到注册表的，因此如果您想推送到 docker 注册表以外的注册表，则需要使用注册表名称或 IP 和端口创建清单列表。这类似于标记图像并将其推送到外部注册表。

创建清单列表的本地副本后，您可以选择 annotate它。允许的注释是架构和操作系统（覆盖图像的当前值）、操作系统特性和架构变体。

最后，您需要将push您的清单列表添加到所需的注册表中。下面是对这三个命令的描述，以及将它们组合在一起的示例。

$ docker manifest create 45.55.81.106:5000/coolapp:v1 \
    45.55.81.106:5000/coolapp-ppc64le-linux:v1 \
    45.55.81.106:5000/coolapp-arm-linux:v1 \
    45.55.81.106:5000/coolapp-amd64-linux:v1 \
    45.55.81.106:5000/coolapp-amd64-windows:v1

Created manifest list 45.55. 81.106: 5000/ coolapp:v1

$ docker manifest annotate 45.55.81.106:5000/coolapp:v1 45.55.81.106:5000/coolapp-arm-linux --arch arm

$ docker manifest push 45.55.81.106:5000/coolapp:v1

检查清单

$ docker manifest inspect coolapp:v1
