serverUuid should follow immediately after the equal sign

[aristosv]

I used this command to install plex inside a docker container running on Debian 9.3

docker create --name=plex -h PlexMediaServer --net=host -e VERSION=latest -e PUID=1001 -e PGID=1001 -e TZ=Asia/Nicosia -v /mnt/containers/plex/config:/config -v /mnt/containers/plex/tvshows:/tvshows -v /mnt/containers/plex/movies:/movies -v /mnt/containers/plex/transcode:/transcode linuxserver/plex

This is the log output https://pastebin.com/seraVtDG

Basically there's an error saying

Error in command line:the argument for option '--serverUuid' should follow immediately after the equal sign

That's usually a harmless message in the log, happens until you login and register your server with your account. Your server may be crashing for a different reason. Check the plex media server log in the config folder.

But the web interface http://192.168.1.41:34200/web is not avaialble

This is the log file. There's a message "The database is locked". But which database?

Plex database. Search on plex forums. It's a common issue. Whenever something else accesses the plex database (an app like plexemail or the user via sqlite client) plex database gets locked or corrupted. You should be able to restore from a backup.

If this is a brand new install, then maybe you have your config folder on a network share? That can also cause issues with sqlite databases. Local folder is recommended

[aristosv]

You're right, the config folder is on a network share. I wanted to use plex in docker because I like the idea of separating the app from its configuration. But if I can't have the configuration on a network share, away from the server running docker, I don't see the point in using plex in a container.

[mauvehed]

I just ran into this same problem. Plex in Docker with /config volume being mounted from a network share (CIFS). Are we saying this is an unsupported method of deployment?

[aptalca]

Correct. Sqlite does not like being on a network share.

You can maybe try things like putting the config folder on a network share but then symlinking the database folder back to a local location. I don't know, maybe that will work.

Why do you guys need to put the config folder on a network share?

I do run plex server in a container and it keeps my linux host clean: no service, no files in /etc, /usr, /var, etc... no service on the linux host, everything is in docker, easy to get rid of and restart on a clean slate, especially when the config is in a mounted directory.
