I have pod deployed on a node with 600gb volume. I only want a pod to have 50gb root disk space.

So I have such config in deployment.yaml:

```auto
          limits:
            ephemeral-storage: "50G"

```

But when I entered the container, I found that all the disk space was allocated to the container

```bash
root@dbe9716daf8890-64fcccfc8-l4vph:/workspace# df -Th
Filesystem Type Size Used Avail Use% Mounted on

/dev/sda4 ext4 662G 484G 145G 77% /etc/hosts
shm tmpfs 64M 4.0K 64M 1% /dev/shm

tmpfs tmpfs 221G 0 221G 0% /proc/scsi
tmpfs tmpfs 221G 0 221G 0% /sys/firmware

```

I’m hoping to find a way to keep the space seen by the df command consistent with the limit value I set
