How can I mount a second disk to a Docker container?

Question

I have a Docker container on Ubuntu. This container uses a PCIe drive and I want to add a SATA drive. Neither drive should share data with other containers.

How can I do this?

From the command docker run? Or through the Dockerfile?

Here's the lsblk on the server:

# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0 744.7G  0 disk
|-sda1        8:1    0   243M  0 part /boot
|-sda2        8:2    0     1K  0 part
|-sda5        8:5    0   976M  0 part
`-sda6        8:6    0 743.5G  0 part /
nvme0n1     259:0    0 349.3G  0 disk
`-nvme0n1p1 259:2    0 349.3G  0 part /media/pcie-disk

Here's the lsblk on the Docker container:

# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0 744.7G  0 disk
|-sda1        8:1    0   243M  0 part
|-sda2        8:2    0     1K  0 part
|-sda5        8:5    0   976M  0 part
`-sda6        8:6    0 743.5G  0 part
nvme0n1     259:0    0 349.3G  0 disk
`-nvme0n1p1 259:2    0 349.3G  0 part /etc/hosts

How are you using the PCIe drive in the container? A [bind mount](https://docs.docker.com/storage/bind-mounts/)? — Matt, Mar 23 '18 at 02:48

Mount the disk to your host at any endpoint, then mount the endpoint to the Docker container as one of its volumes.

this does not a work. A volume is exposed as a mountpoint, not as a disk in /dev – Friendly Genius Mar 29 '18 at 00:26
