Plex Setup on TrueNAS

My TrueNAS Scale box is already built, online, and accessible on my network. The next step is getting Plex installed cleanly—and I would like to start there before we move on to Nextcloud or Tailscale.

Here’s what I need from you:
• Install Plex on TrueNAS Scale, preferably using whatever method you feel is most stable for long-term maintenance (official app catalog, TrueCharts, Docker, etc.).
• Configure it so that I can reach the server remotely with my existing Plex account. NAT rules or Tailscale can be part of the solution as long as remote streaming works reliably outside my LAN.
• Point Plex to the media datasets already created on the pool, set the correct permissions, and verify libraries scan without errors.
• Confirm hardware transcoding is enabled (the server has an Intel iGPU) and test a transcode to prove it works.

Acceptance criteria: I can log in to Plex from the internet, see my organized libraries, and successfully play a movie that transcodes on the fly without stuttering.

If everything checks out we can schedule follow-up work for Nextcloud and Tailscale, but for now let’s get Plex running perfectly.
