我用下载的镜像创建的容器后发现如下问题:1.容器里看不到内核的版本.这是为什么,他不是基于内核版本吗?为什么容器里面看不到? 2.用下载的centos:6创建的容器里使用iptables -nL时报错: FATAL: Could not load /lib/modules/2.6.32-504.el6.x86_64/modules.dep: No such file or directory iptables v1.4.7: can't initialize iptables table `filter': Permission denied (you must be root) Perhaps iptables or your kernel needs to be upgraded.
