使用github action 配合 docker buildx 编译 arm64 docker-compose

说明

git 上搜索了很多 docker-compose 的 arm64 的编译基本都是使用 qemu-user-static 之类的设置下后编译的,也看到过用特权容器启动 qemu-user-static 或者 binfmt 之类的,但是我自己机器上试了无效,貌似是因为我操作系统是低版本内核的 centos ,github 上搜了下,其他很多人的编译感觉太啰嗦了。就在 action 上整了下,测试是可用的,而且非常简单。

docker-practice/actions-setup-docker@master 将会在在 action 的 runner 里安装 docker,创建 buildx 和 运行 docker run --rm --privileged ghcr.io/dpsigs/tonistiigi-binfmt:latest --install all

编译过程看 compose 仓库的 makefile,是运行的 https://github.com/docker/compose/blob/master/script/build/linux 这个脚本。所以克隆 compose 仓库后进目录里,然后 checkout 指定 tag。官方的编译过程都是在 docker build 产生的容器里去编译的。最后有个 build –output就是直接把文件给整出来。我这里是用的 buildx 去替代 build 编译。理论上也可以编译其他架构的,我仓库已经自动化处理这个过程了。 https://github.com/zhangguanzhang/docker-compose-aarch64/releases。
