5.8. 挂载容器文件系统

流程

1. 运行名为 mysyslog 的容器：

   # podman run -d --name=mysyslog registry.redhat.io/rhel8/rsyslog

2. 可选：列出所有容器：

   # podman ps -a
   CONTAINER ID  IMAGE                                    COMMAND          CREATED         STATUS                     PORTS   NAMES
   c56ef6a256f8  registry.redhat.io/rhel8/rsyslog:latest  /bin/rsyslog.sh  20 minutes ago  Up 20 minutes ago                  mysyslog

3. 挂载 mysyslog 容器：

   # podman mount mysyslog
   /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged

4. 使用 ls 命令显示挂载点的内容：

   # ls /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged
   bin  boot  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

5. 显示 OS 版本：

   # cat /var/lib/containers/storage/overlay/990b5c6ddcdeed4bde7b245885ce4544c553d108310e2b797d7be46750894719/merged/etc/os-release
