Issue during Docker installation with "-v /opt/mqtt-bridge:/config"

[wonderwareguru]

I'm getting this response in the CL:
"docker: Error response from daemon: error while creating mount source path '/opt/mqtt-bridge': mkdir /opt/mqtt-bridge: read-only file system."

can anyone shed some light on how to resolve this?

Thanks

you can change directory path like

$ sudo docker run -d --name="mqtt-bridge" -v ~/config/mqtt-bridge:/config -p 8080:8080 smartthings-mqtt-bridge
