docker buildx 只能联网使用

Question

背景：
在x86平台构建arm镜像，
CentOS Linux release 7.8.2003 (Core)
Docker version 20.10.22, build 3a2c30b
.
.
过程：
设置属性，重启："experimental": true,

docker buildx install
docker buildx create --platform=linux/arm64 --name arm64-hn
docker buildx use arm64-hn

cat Dockerfile
FROM nginx:stable-perl
LABEL maintainer=".cn"
RUN mkdir -p /opt/test
RUN nginx -v

docker buildx build --platform=linux/arm64 -t  test  .  --load

成功，镜像传到arm，可用！

问题：
1、只能联网使用，搜索了一遍，说是要获取manifest。
2、docker build -t test . --load X86的构建不能用了！命令执行后，会像断网时的 buildx
两情况报错基本相同，如下：

折腾了几天，搜索几圈也没见相关内容。
求各位指点一下问题解决方向。万分感谢！

以下回复参考：皆我百晓生、券券喵儿等免费微信小程序作答:

问题1：只能联网使用，搜索了一遍，说是要获取manifest。

解决方案：确保你的Docker守护进程可以访问互联网，以便它可以下载所需的镜像和manifest。如果你的网络环境有限制，可以尝试配置代理或者使用私有镜像仓库。

问题2：docker build -t test . --load X86的构建不能用了！命令执行后，会像断网时的 buildx

解决方案：这个问题可能是由于Docker版本不兼容导致的。你可以尝试升级Docker到最新版本，然后再次尝试构建镜像。如果问题仍然存在，可以考虑在Docker官方论坛或GitHub仓库提交一个issue，寻求官方支持。
