Run once for all libraries?

[markfaine]

The docker instructions seem to show that I need to run it once per library, is this correct or am I missing something, is there a way to run it once but for all libraries? If not, could there be?

Thanks, just getting started looking at it but it looks really nice.

The folder structure is given by your plex configuration. That means when you run plex in a docker container and passthrough a media folder such as /source/media on the root machine to /media in the plex container, plex will index it's library relative to /media, not /source/media. When the metadata script runs the export process, it fetches the library paths relative to the plex container (/media). That means if your libraries are all in this parent /media folder, the script can export metadata for multiple libraries.

However, the exporter is not capable of dealing with multiple passed through locations of the root machine.

Thanks, I kind of eventually figured it out. I'm not running plex in docker but I was hoping to run the metadata exporter in docker just for simplicity, fewer things to install, etc. I intend to run it with the 'once' option with cron outside of the container on the host. I have several libraries. They are all relative to /volume1, for example /volume1/movies /volume1/television, etc. So I tried,
docker run --rm -e ... -v /volume1:/media plex-media-exporter once and I had some success after I included -e NODE_TLS_REJECT_UNAUTHORIZED=0 , however I eventually got stuck again with a different error:

/usr/src/app/index.js:9
const plexRootFolder = process.env.PLEX_ROOT_FOLDER.replace(/\/$/, ''); // remove trailing slash
                                                    ^

The error message looks like you haven't defined the PLEX_ROOT_FOLDER env variable or passed somthing that's not a string. Try setting it like this:

docker run \
-e PLEX_ADDRESS='...' \
-e X_PLEX_TOKEN='...' \
-e PLEX_ROOT_FOLDER='/volume1' \
-e FILE_ENDING_PATTERN='...' \
-v /volume1:/volume1 \
once

Most likely, it also works with /media when you've set the right env vars. However, maybe there are other issues with nodejs and it's dependencies - I haven't run the exporter since years^^

Jumping in on this issue as I think it may be somewhat related. I am running this on a Windows machine without Docker involved. My media is split across two physical drives, both with a X:/Media root path. It was very unclear what I needed to pass for the environment variable.

I eventually tried to pass an empty string ("") for the environment variable, and that seems to have made it happy. Not the most intuitive but it got me by.

I also replaced all of the directory writeFile calls with path.join() and the file structure. Not sure if it was placebo, but it does seem to have helped. I may make a PR with the simple change depending on how well I can get this to work for me.
