Unable to attach additional volume to my jenkins container

I have tried a lot of commands as shown in the tutorial but always getting this output:

docker run requires atleast 1 argument.
See docker run --help

Hello @1804524
I am not familiar with the PowerShell. Can you try to run in the CMD prompt?

I did in CMD, it says now
“Invalid reference format”

Please paste the command here.
