You’ll need to double-check the tagging of your container.
You should be using either public or beta:
These two images do not have any Plex Media Server binary installed. Instead, when these containers are run, they will perform an update check and fetch the latest version, install it, and then continue execution. They also run the update check whenever the container is restarted. To update the version in the container, simply stop the container and start container again when you have a network connection. The startup script will automatically fetch the appropriate version and install it before starting the Plex Media Server.
Gotcha, so I did docker pull plexinc/pms-docker:beta , and it pulled the new image.
However, just doing standard docker start plex, it is not running anything updates. I assume I need to tell it to run the beta image? I must be missing something simple =(
