[BUG] Plex compose install issue

[fanidev]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I have issue with plex installation using non-root account
As I found, there are two images for plex, each will set different Env parameters, one of them significantly less

for example, one will set HOME=/config and other to /root, no metter what I put in yml
If I manage to install somehow, playing with parameters, there are other problems with running.

Basically with the standard file and settings I get error

plex | libc++abi: terminating with uncaught exception of type std::runtime_error: Codecs: Initialize: 'boost::filesystem::status: Permission denied [system:13]: "/run/plex-temp"' plex | ****** PLEX MEDIA SERVER CRASHED, CRASH REPORT WRITTEN: /config/Library/Application Support/Plex Media Server/Crash Reports/1.42.1.10054-f333bdaa8/PLEX MEDIA SERVER/712e5549-c89e-4aef-611f6aae-a94af957.dmp

all permission are ok

Expected Behavior

No response

Steps To Reproduce

Before installing:
pwd /srv/dev-disk-by-uuid-08bbb3c0-2223-4d86-9281-1eec8ff330e7/appdata root@irfanas:/srv/dev-disk-by-uuid-08bbb3c0-2223-4d86-9281-1eec8ff330e7/appdata# ls -ld * -rw-rw-r-- 1 root users 1298 Aug 11 14:10 global.env root@irfanas:/srv/dev-disk-by-uuid-08bbb3c0-2223-4d86-9281-1eec8ff330e7/appdata#

Read the read-only page linked in the readme, it explicitly calls out at least one of the things you mention.

Read the read-only page linked in the readme, it explicitly calls out at least one of the things you mention.

I don't know which part you mean exactly?

I did it again:
docker rm plex
delete all files
create new yml, same as in readme
same error again
Its working with root user, but i donit want to use it

[fanidev]

Env from inspect:
"Env": [ "TZ=Europe/Sarajevo", "VERSION=docker", "PLEX_CLAIM=claim-XLB14LEZUQpxciuBHWXa", "PUID=1002", "PGID=100", "PATH=/lsiopy/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "HOME=/root", "LANGUAGE=en_US.UTF-8", "LANG=en_US.UTF-8", "TERM=xterm", "S6_CMD_WAIT_FOR_SERVICES_MAXTIME=0", "S6_VERBOSITY=1", "S6_STAGE2_HOOK=/docker-mods", "VIRTUAL_ENV=/lsiopy", "LSIO_FIRST_PARTY=true", "NVIDIA_DRIVER_CAPABILITIES=compute,video,utility,graphics", "DEBIAN_FRONTEND=noninteractive", "PLEX_DOWNLOAD=https://downloads.plex.tv/plex-media-server-new", "PLEX_ARCH=amd64", "PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/config/Library/Application Support", "PLEX_MEDIA_SERVER_HOME=/usr/lib/plexmediaserver", "PLEX_MEDIA_SERVER_MAX_PLUGIN_PROCS=6", "PLEX_MEDIA_SERVER_USER=abc", "PLEX_MEDIA_SERVER_INFO_VENDOR=Docker", "PLEX_MEDIA_SERVER_INFO_DEVICE=Docker Container (LinuxServer.io)", "TMPDIR=/run/plex-temp" ],

This Env "HOME=/root" , is it path from os root? Why is it set like that?

[fanidev]

As described in Running Containers As A Non-Root User
I added line
user: 1002:100
With that i have this error
mkdir: cannot create directory ‘/config/Library’: Permission denied
Its because the "config" dir is created as root owner, and I dont know why

-rw-rw-r-- 1 root users 180 Sep 10 13:59 compose.override.yml drwxr-xr-x 2 root root 4096 Sep 10 13:59 config -rw-rw-r-- 1 root users 201 Sep 10 13:59 plex.env -rw-rw-r-- 1 root users 1157 Sep 10 13:59 plex.yml

[Roxedus]

None of the non-root log lines are in your log. How exactly is this running? rootless daemon?

Docker is installed as openmediavault-cimpose plugin

[fanidev]

Without this line "user: 1002:100" directory is created and this is result
-rw-rw-r-- 1 root users 180 Aug 15 00:02 plex/compose.override.yml **drwxr-xr-x 3 appuser users 4096 Aug 15 00:04 plex/config** -rw-rw-r-- 1 root users 201 Aug 15 00:02 plex/plex.env -rw-rw-r-- 1 root users 1012 Aug 15 00:02 plex/plex.yml drwxr-xr-x 2 root root 4096 Aug 15 00:04 plex/transcode

But when I have yml with specified user via the --user parameter , config dir is created with root root privileges ???

[thespad]

As you will know from having read the documentation, if you run as a non-root user you are responsible for manging all file permissions as the container will not have the ability to set host permissions.
