编译arm版docker(10代i74c4g编译1小时)

需要安装dockerbuildx

docker buildx create --use --name=mybuilder-cn --driver docker-container --driver-opt image=uhub.service.ucloud.cn/iatc/cn-buildkit:latest
docker buildx use mybuilder-cn
docker buildx build --platform linux/arm/v7 -t openresty-arm:latest . --load
docker buildx rm mybuilder-cn

在x86机器上运行armv7版

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker run -it --platform=linux/arm/v7 openresty-arm:latest

docker版的helloworld

docker exec -it openresty sh
cd /usr/local/openresty/nginx/conf
#编辑nginx.conf 将location/内容替换为location / {default_type text/plain;content_by_lua_block {ngx.say("Hello World")}}
#然后保存
#最后重载配置
/usr/local/openresty/nginx/sbin/nginx -s reload
