使用 SLES15 和 *Suse Container 时在 Docker Container 中没有访问权限

Question

我在 SLES15 (GNU/Linux 4.12.14) 上运行 Docker 18.09.6。启动任何 suse 容器跳跃/风滚草或 sle15 时，我没有适当的访问权限来查看 ls -l。其他容器镜像如 Alpine 和 Ubuntu 可以正常工作。 在这两种情况下，我都是id -u = 0，根据whoami 是root。

示例：

275b1cf2bd20:/ # ls -l
ls: cannot access 'sbin': Operation not permitted
ls: cannot access 'sys': Operation not permitted
ls: cannot access 'usr': Operation not permitted
ls: cannot access 'proc': Operation not permitted
ls: cannot access 'bin': Operation not permitted
ls: cannot access 'tmp': Operation not permitted
ls: cannot access 'selinux': Operation not permitted
ls: cannot access 'boot': Operation not permitted
ls: cannot access 'home': Operation not permitted
ls: cannot access 'root': Operation not permitted
ls: cannot access 'dev': Operation not permitted
ls: cannot access 'var': Operation not permitted
ls: cannot access 'run': Operation not permitted
ls: cannot access 'lib64': Operation not permitted
ls: cannot access 'opt': Operation not permitted
ls: cannot access 'srv': Operation not permitted
ls: cannot access 'mnt': Operation not permitted
ls: cannot access 'lib': Operation not permitted
ls: cannot access 'etc': Operation not permitted

这里发生了什么？

当我尝试在不同的主机上运行基于 SLES 的容器时遇到了类似的问题（即主机的操作系统与 SLES 不同）

如果 docker 镜像和主机基于相同的操作系统，那么ls -l 或ls -n 应该没有权限问题
