Issues mounting with host dir

[zephiowl]

sudo docker run -v HDD/game-hosting/mc-xvr:/data --name xvrtest --net=host -d -it -e EULA=TRUE -e MEMORY=5G itzg/minecraft-server

docker: Error response from daemon: create HDD/game-hosting/mc-xvr: "HDD/game-hosting/mc-xvr" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.
See 'docker run --help'.

When using -v arguments with docker run, then the host directory has to be an absolute path. Docker compose files let you use relative paths, so I prefer using that to avoid the annoyance of -v
