# Docker -- docker manifest
使 Docker 宿 `Linux x86_64` 使 `Linux x86_64`
> WindowsmacOS 使 [binfmt_misc](https://docs.docker.com/docker-for-mac/multi-arch/) 提供了多种架构支持,在 Windows、macOS 系统上 (x86_64) 可以运行 arm 等其他架构的镜像。
`Linux x86_64` `username/test`
```docker
FROM alpine
CMD echo 1
```
Docker Hub `Linux arm64v8` 使
```bash
$ docker run -it --rm username/test
```
`Linux x86_64` `Linux arm64v8` `username/test` `username/arm64v8-test` 使
Docker
`Linux x86_64` `Linux arm64v8` `$ docker run golang:alpine go version`
`golang:alpine` [`manifest` ](https://docs.docker.com/registry/spec/manifest-v2-2/)。
Docker `manifest` Docker Docker `golang:alpine` `username/test`
使 `$ docker manifest inspect golang:alpine` `manifest`
> [](../install/experimental)
