Steps:

1. Create a new container using the following command: docker run -d --name=plex --restart=unless-stopped -v /plex:/config -v /media:/media -p 1900:1900/udp -p 32469:32469 -p 3005:3005 -p 5353:5353/udp -p 8324:8324 -p 32410:32410/udp -p 32412:32412/udp -p 32413:32413/udp -p 32414:32414/udp -p 32400:32400 -e X_PLEX_TOKEN=<token> wernight/plex-media-server:autoupdate
