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。
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 u one name to refer to the same image built for multiple architectures.
To e help for a subcommand, u:
docker manifest CMD --help
For full details on using docker manifest lists, e the registry v2 specification.
EXPERIMENTAL:
docker manifest is an experimental feature.樱花的寓意
Experimental features provide early access to product functionality. The
features may change between releas without warning, or can be removed from a
future relea. Learn more about experimental features in our documentation:
/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:
--incure Allow communication with an incure registry
-v, --verbo Output additional info including layers and platform
manifest create 清单创建
$ docker manifest create --help
Usage: docker manifest create MANIFEST_LIST MANIFEST []
Create a local manifest list for annotating and pushing to a registry
Options:
-a, --amend Amend an existing manifest list
--incure Allow communication with an incure 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:
--incure Allow push to an incure 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--incure标志。对于查询注册表的每个事务，例如 create，--incure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，--incure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。
