问题解决了。

我还在https://app.element.io/#/room/#podman:fedoraproject.org的播客室里发布了这个问题。

我建议使用podman重置(命令跟踪在下面)，然后它对storage.conf的抱怨，我删除了该文件，并做了重新设置。那它起作用了。

我仍然想知道storage.conf内部是什么导致了这个问题，但在调查之前我删除了它。最后，它起了作用，我能够继续。希望能帮上忙。

注意:将删除的storage.conf文件和podman重置后，我也尝试使用docker来检查docker是否对storage.conf文件有任何依赖，但是没有，对接构建也成功执行(下面的命令跟踪)

root@cks-master:~# podman system reset -f
A storage.conf file exists at /etc/containers/storage.conf
You should remove this file if you did not modified the configuration.

root@cks-master:~# rm /etc/containers/storage.conf

root@cks-master:~# podman system reset -f

root@cks-master:~# podman build -t simple -f /vagrant/files/ch5Dockerfile .
