Cannot execute docker run command because I cannot specify where it must download and run containers

Good day,

I’m trying to install docker on a specific external disk because of space constraints. But no matter what I try it sill defaults to the wrong path, not the one explicitly specify:

OS :
Ubuntu 22.04.5 LTS
COMMAND:

The command (latest one with various flag I tried) :

docker run -v /media/root/STORAGE -it --rm --gpus all --shm-size=16GB -e NGC_API_KEY -v “$LOCAL_NIM_CACHE:/opt/nim/.cache” -p 8000:8000 nvcr.io/nim/qwen/qwen3-next-80b-a3b-thinking:latest

disks on the unit:
Filesystem Size Used Avail Use% Mounted on
/dev/mmcblk0p1 54G 32G 20G 63% / (****!! ` It keeps using this one ?? )**

tmpfs 15G 208K 15G 1% /dev/shm
tmpfs 6.0G 44M 6.0G 1% /run
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
/dev/mmcblk0p10 63M 118K 63M 1% /boot/efi
tmpfs 3.0G 120K 3.0G 1% /run/user/1000
tmpfs 3.0G 1.7M 3.0G 1% /run/user/0

/dev/nvme0n1 916G 48K 870G 1% /media/root/STORAGE (---->>>> this is the one I want to use <<<------`)

It will always use the data-root folder, which is by default /var/lib/docker, unless you configure it to use a different folder as data-root (see: https://docs.docker.com/engine/daemon/#daemon-data-directory). You can mount a different disk to the path /var/lib/docker and make it use a different disk.

Though, nothing in your docker run command is related to this. What you try to do is to mount a volume into a conatiner path. If you want to bind a host folder into a container folder, you will need to use -v <host path>:<container path> and not just -v <container path>.
