### 如何使用docker desktop 下载x86、amd64、arm64 镜像？ ###

*  环境
 *  修改配置
 *  重启docker后下载镜像
 *  验证镜像架构

# 环境 #

![在这里插入图片描述][watermark_type_ZHJvaWRzYW5zZmFsbGJhY2s_shadow_50_text_Q1NETiBAW3NoZW5ob25nbGVpXQ_size_19_color_FFFFFF_t_70_g_se_x_16_pic_center]

# 修改配置 #

[官网地址，开启 Docker CLI 的实验特性][Docker CLI]  
docker desktop 的Preferences=>>Docker Engine  
experimental 的值设置成 true，意思是：开启manifest实验特性

      "experimental": true
    }

# 重启docker后下载镜像 #
