config.yml file does not exist

[abzaatari]

Hi all,
I install mqtt bridge in raspberry pi 3A in docker container.
I execute this command:
To run it (using /opt/mqtt-bridge as your config directory and 8080 as the port):
$ docker run
-d
--name="mqtt-bridge"
-v /opt/mqtt-bridge:/config
-p 8080:8080
stjohnjohnson/smartthings-mqtt-bridge.
The smatthings mqtt bridge is installed but not running, and opt/mqtt-bridge directory is empty and no permission to create any file in it. I try to change the directory, the same still empty no permission.
Please any help to solve this issue!
Thanx.
