docker buildx 没有其他平台怎么办？

我的平台是 x86，我想要构建多平台镜像，但是 docker buildx ls 但是没有 arm 和 mips 等等其他平台

╰─➤  docker buildx ls                                                                                                                                                                                                                                                                      1 ↵

怎么办？怎么让 arm 这些东西都出现？

我参考了：构建多架构镜像的最佳实践

然后在命令行输入 docker run --privileged --rm tonistiigi/binfmt --install all

─➤   docker run --privileged --rm tonistiigi/binfmt --install all
