Windows平台打包
安装Docker Desktop docs.docker.com
docker build -f ./build/docker/Dockerfile --platform=linux/arm64,linux/amd64 -t csop:latest .
该命令将同时打出arm和amd镜像
Linux
参考：https://docs.docker.com/build/guide/multi-platform/
vim /etc/docker/daemon.json
添加以下内容
{
"experimental": true, //低版本docker时需要添加此行
"features": {
"containerd-snapshotters": true
}
}
重启docker服务
systemctl daemon-reload
systemctl restart docker.service
安装模拟器
apt-get install qemu qemu-user-static binfmt-support
老版本docker中，如果Dockerfile from的镜像已经在amd机器上存在，则不会去下载arm64镜像，打包出的镜像是amd64的。需要先下载对应平台的基础镜像，再使用docker build --platform=linux/arm64
Golang使用Docker打包多平台
查看docker buildx支持的多平台
docker buildx ls

拉取mipse64版本golang镜像(科学上网)
docker pull golang:1.23.0 --platform=linux/mips64le
支付loong64架构
创建一个新的 buildx 实例,并添加 loong64 架构支持:
docker buildx create --name gjing1st --platform linux/amd64,linux/arm64,linux/loong64,linux/mips64le
切换到刚刚创建的 buildx 实例:
docker buildx use gjing1st
验证 buildx 实例是否已经支持 loong64 架构:
docker buildx inspect --bootstrap
输出结果应该包含 linux/loong64 架构:

打包多平台
以下默认打包arm64
# syntax=docker/dockerfile:1
ARG PLATFORM=arm64
ARG ALPINE_VERSION=3.20
ARG GO_VERSION=1.23.0
# 多阶段构建
#构建一个 builder 镜像，目的是在其中编译出可执行文件mck
#构建时需要将此文件放到代码根目录下

RUN go build -ldflags="-s -w" -o statistic ./cmd/statistic/main.go
FROM gjing1st/alpine-${PLATFORM}:${ALPINE_VERSION}
##更新软件源
#RUN apk update --no-cache && apk add --no-cache tzdata
##设置本地时区，这样我们在日志里看到的是北京时间了
#ENV TZ Asia/Shanghai
WORKDIR /home
COPY --from=builder /build/src/statistic /home/statistic
CMD ["./statistic"]
EXPOSE 9681
# docker build --build-arg PLATFORM=arm64 -t statistic:v4.0.0 .
开始构建:
#打包arm
docker build --build-arg PLATFORM=arm64 --platform=linux/arm64 -t upserver:v4.0.0 .
# 打包amd
docker build --build-arg PLATFORM=amd64 --platform=linux/arm64 -t upserver:v4.0.0 .
# 打包mipse
docker build --build-arg PLATFORM=mipse64le --platform=linux/arm64 -t upserver:v4.0.0 .
注意本地需要有对应名称的不同架构的名称
