There is no limit to the container's free, and I still see the memory size of the host, so I feel I need to increase the LXCFS to implement it

After running debug, this is still the case, there is no limit, see the container resource visibility is still the host

```
bash-5.0# free -m
total used free shared buff/cache available
Mem: 7820 4423 712 0 2685 3053
Swap: 0 0 0
bash-5.0# exit
exit
[root@master ~]# free -m
total used free shared buff/cache available
Mem: 7820 4012 1006 45 2802 3347
Swap: 0 0 0

```

Remember that there is a project called LXCFS that can achieve the visibility of resources, you can see the visibility of container resources, the author here can be optimized, I don't know if I am right, I hope to get correction

No source file, test, or entry point is identified in the report. Start by reviewing the referenced LXCFS resource-visibility approach alongside kubectl-debug's container behavior; done means the container reports its configured memory limit rather than the host's memory size.
