Docker installation Linux

[Morrisman68]

Hello,

I'm trying to install 2.2 via docker on Ubuntu 26., but get an error message from:

docker create -v host-content-dir:/Music:ro --network host --name container-name minimserver:2.2

when I replaced /Music:ro with my own folder name - /mnt/blake_road/sounds and also
a container-name of my own choosing - in this case, minimserver.

The error produced is:

unknown shorthand flag: 'v' in -v

Usage: docker service create [OPTIONS] IMAGE [COMMAND] [ARG...]

Any ideas or updates, please?

Many thanks,

Ben
