因为一直使用的时amd64的镜像包，最近部署的服务器上都是arm64的，需要重新Build镜像。打包时一直出现下面的问题：

docker buildx build --platform linux/arm64 -t xxxx:v2.0.0-arm64 --load .

原因
#

我是在Windows中安装了Docker Desktop。但是它默认会自带Buildx：

docker buildx ls
NAME/NODE           DRIVER/ENDPOINT     STATUS     BUILDKIT   PLATFORMS
default             docker
 \_ default          \_ default         running    v0.32.2    linux/amd64 (+3), linux/arm64, linux/arm (+2), linux/ppc64le, (2 more)
desktop-linux       docker
 \_ desktop-linux    \_ desktop-linux   running    v0.32.2    linux/amd64 (+3), linux/arm64, linux/arm (+2), linux/ppc64le, (2 more)

但是我又重新创建了一个名为rebuilder的Buildx

docker buildx create --name rebuilder --use

此时，打包就会报错。

然后我又想到使用本机代理

docker buildx rm rebuilder
docker buildx create --name rebuilder `
>   --driver docker-container `
>   --driver-opt network=host `
>   --use

依旧报错。 那就指定代理：使用了局域网IP，以及开启了局域网连接。

docker buildx create --name rebuilder `
>   --driver docker-container `
>   --driver-opt env.HTTP_PROXY=http://172.16.10.53:7897 `
>   --driver-opt env.HTTPS_PROXY=http://172.16.10.53:7897 `
>   --use

依旧报错。 暂时没空研究原因时为啥todo一下。

解决

docker buildx ls
NAME/NODE           DRIVER/ENDPOINT     STATUS    BUILDKIT   PLATFORMS
rebuilder*          docker-container
 \_ rebuilder0       \_ desktop-linux   running   v0.32.2    linux/amd64 (+3), linux/arm64, linux/arm (+2), linux/ppc64le, (3 more)
default             docker
 \_ default          \_ default         running   v0.32.2    linux/amd64 (+3), linux/arm64, linux/arm (+2), linux/ppc64le, (2 more)
desktop-linux       docker
 \_ desktop-linux    \_ desktop-linux   running   v0.32.2    linux/amd64 (+3), linux/arm64, linux/arm (+2), linux/ppc64le, (2 more)

看到了自带的desktop-linux，那就试试吧

docker buildx use desktop-linux

然后执行打包命令

docker buildx build --platform linux/arm64 -t xxx:v2.0.0-arm64 --load .

丝滑！！！但是Why?
