The `--device-read-bps` flag limits the read rate from a device. For example,
this command creates a container and limits the read rate to `1mb` per second
from `/dev/sda`:
The `--device-read-bps` flag limits the read rate (bytes per second) from a device.
For example, this command creates a container and limits the read rate to `1mb`
per second from `/dev/sda`:
$ docker run -it --device-read-bps /dev/sda:1mb ubuntu
The `--device-write-bps` flag limits the write rate to a device. For example,
this command creates a container and limits the write rate to `1mb` per second
for `/dev/sda`:
The `--device-write-bps` flag limits the write rate (bytes per second)to a device.
