ARMv8架构下，docker模拟X86架构

一、docker获取arm架构centos镜像，构建镜像

执行docker pull centos:7.9.2009 --platform=arm64，获取arm64架构版本centos7.9镜像

##拉取arm64架构版本centos7.9镜像
orangepi@orangepi5:~$ docker pull centos:7.9.2009 --platform=x86
Error response from daemon: "x86": unknown operating system or architecture: invalid argument
orangepi@orangepi5:~$ docker pull centos:7.9.2009 --platform=x86-64
7.9.2009: Pulling from library/centos

Status: Downloaded newer image for centos:7.9.2009
docker.io/library/centos:7.9.2009

执行docker inspect centos:7.9.2009，查看镜像版本信息

orangepi@orangepi5:~$ docker inspect centos:7.9.2009
