LMS in Docker on RPi

Looking at running LMS in Docker on an existing RPi that already has Libreelec installed.

I've got Docker installed and successfully runs Hello World.

Looking for the 'best' LMS RPi container. Which one is most widely used?

Then looking for some step-by-step guides for configuring the RPi and the Docker start commands for the LMS container to mount my music which will be shared via NFS off a NAS.

Any good guides out there? (I found lots for setting up Docker, but none on the LMS containers)

Thanks.
