rocky linux 8.10 下的 podman 配置镜像加速

通过毫秒镜像提供的镜像加速，见https://mdoc.cc/mliev/1ms/v1.0.0/18，如下：

[root@localhost ~]# cd /etc/containers/
certs.d/           oci/               registries.conf.d/ registries.d/      systemd/           
[root@localhost ~]# cd /etc/containers/registries.conf.d
[root@localhost registries.conf.d]# ll
