```
# rm -rf /var/lib/kubelet/*
# docker run --rm -ti -v /var/lib/kubelet:/var/lib/kubelet fedora /bin/bash
bash-4.3# ls -l /var/lib/kubelet/
total 0
```
------
Outside of the container, on the host
```
# mkdir /var/lib/kubelet/subdir
# mount -t tmpfs /var/lib/kubelet/subdir/ /var/lib/kubelet/subdir/
# touch /var/lib/kubelet/subdir/inside_tmpfs

```
------
Now back inside the container
```
bash-4.3# ls -l /var/lib/kubelet/
total 0
drwxrwxrwt. 2 root root 60 Apr 20 15:16 subdir
bash-4.3# ls -l /var/lib/kubelet/subdir/
total 0
-rw-r--r--. 1 root root 0 Apr 20 15:16 inside_tmpfs

# touch /var/lib/kubelet/subdir/inside_tmpfs2
```
------
And back outside:
```
# ls -l /var/lib/kubelet/subdir/
total 0
-rw-r--r--. 1 root root 0 Apr 20 15:16 inside_tmpfs
-rw-r--r--. 1 root root 0 Apr 20 15:20 inside_tmpfs2
```

# And now if we mount inside the container
```
# docker run --rm -ti -v /var/lib/kubelet:/var/lib/kubelet --privileged fedora /bin/bash
bash-4.3# mkdir /var/lib/kubelet/subdir
bash-4.3# mount -t tmpfs /var/lib/kubelet/subdir /var/lib/kubelet/subdir
bash-4.3# touch /var/lib/kubelet/subdir/mount_from_inside_container
```
