Create a new container using the image located at:

lscr.io/linuxserver/tvheadend:latest

Now add volumes for the Tvheadend config files, recordings, and time zone environment variables:

/tvheadend:/tvheadend:rw
/recordings:/recordings:rw
/etc/timezone:/etc/timezone:ro
/etc/localtime:/etc/localtime:ro

Last, you need to change the network to “Host” mode in order for the HDHomerun tuner(s) to work.
