记录下amd64平台下，Docker 构建多环境平台报错后的解决方法。
我自己的电脑系统是X86_64(amd64)平台，想构建多环境平台的镜像，并推送镜像到Harbar，在执行命令
docker buildx build --platform linux/amd64,linux/arm64 -f ./Dockerfile -t "harbor.xxxx.net/ailp/ee/frontend/app:v3.0.3.9" .
时报错如下：
=> ERROR [internal] booting buildkit 15.3s
=> => pulling image moby/buildkit:buildx-stable-1 15.3s
------
> [internal] booting buildkit:
------
WARNING: No output specified with docker-container driver. Build result will only remain in the build cache. To push result image into registry use --push or to load image into docker use --load
ERROR: failed to build: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
报错上说有两个问题：
- 网络连接问题，意思就是镜像源需要配置国内镜像加速器
- 构建命令中没有指定输出方式，意思就是需要在命令行后增加–push
针对报错问题进行解决：
步骤一：打开Docker Desktop小鲸鱼图标应用，在设置中找到Docker Engine中配置镜像源，然后重启Docker Desktop应用，点击左下角，切换状态，点击Restart，重新启动服务。注意一定要重新启动配置的镜像源才会生效
"registry-mirrors": [
"https://docker.m.daocloud.io/",
"https://huecker.io/",
"https://dockerhub.timeweb.cloud",
"https://noohub.ru/",
"https://dockerproxy.com",
"https://docker.mirrors.ustc.edu.cn",
"https://docker.nju.edu.cn",
"https://xx4bwyg2.mirror.aliyuncs.com",
"http://f1361db2.m.daocloud.io",
"https://registry.docker-cn.com",
"http://hub-mirror.c.163.com",
"https://docker.mirrors.ustc.edu.cn"
]
想要验证镜像源是否配置成功，可打开终端，输入命令 docker info ，如果Registry Mirrors下能输出刚配置的镜像源，则镜像源配置成功
docker info
正常输出如下：

步骤二：在构建命令后增加–push，指定输出方式
docker buildx build --platform linux/amd64,linux/arm64 -f ./Dockerfile -t "harbor.xxxx.net/ailp/ee/frontend/app:v3.0.3.9" --push .
正确输出如下，则构建成功
