$ docker run --rm --privileged docker/binfmt:820fdd95a9972a5308930a2bdfb8573dd4447ad3

由于 Docker 默认的 `builder` 实例不支持同时指定多个 `--platform`，我们必须首先创建一个新的 `builder` 实例。
由于 Docker 默认的 `builder` 实例不支持同时指定多个 `--platform`，我们必须首先创建一个新的 `builder` 实例。同时由于国内拉取镜像较缓慢，我们可以使用配置了 [镜像加速地址](https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md) 的 [`dockerpracticesig/buildkit:master`](https://github.com/docker-practice/buildx) 镜像替换官方镜像。
```bash
$ docker buildx create --name mybuilder --driver docker-container
# 适用于国内环境
$ docker buildx create --use --name=mybuilder-cn --driver docker-container --driver-opt image=dockerpracticesig/buildkit:master
# $ docker buildx create --name mybuilder --driver docker-container
$ docker buildx use mybuilder
```
