Unable to set the permission right on config directory

Server Version#: plexinc/pms-docker:latest

I am unable to get things started properly with plex.

After running the docker, here are the logs I see.

[santosh@SRCS docker_mounts]$ docker logs plex

I started the contained with a macvlan driver like so:

docker run -d --name plex --net=srv_net --ip=172.16.11.6 --dns=172.16.11.10 -e TZ=“America/Los_Angeles” -e PLEX_CLAIM=“claim-XXXX” -e ADVERTISE_IP=“http://ple:32400/” -h Media -v /srv/docker_mounts/plex:/config:rw -v /media/transcode:/transcode:rw -v /media/data:/data:ro plexinc/pms-docker

permisson on /srv/docker_mounts/plex:

drwxr-xr-x. 2 santosh docker 4096 Aug 26 20:40 plex
santosh@SRCS docker_mounts]$ id whoami

uid=1000(santosh) gid=100(users) groups=100(users),1000(docker)

The uid and gid inside and outside the container matches.

Ive tried numerous iterations and even reinstalled image etc… wtih no luck. Would appreciate any help!!

You don’t mention what OS is running on the host so I will guess Ubuntu or derivative. Under Ubuntu the /media folder has special permissions that protect files on a per user basis. Config and transcode need RWX not just RW. Unless you are actually trying to connect to a specific Vlan, I would just use the HOST network option at first to minimize setup problems.

sansadk · August 27, 2019, 4:00pm

Hi Thanks for responding. The host is running fedora 25. This specific configuration worked well for me in the past. In fact I can ping this container with no issues. I had a power reset and when the server came back up I ran into a crash. In attempt to fix that, I ended up blowing away all the files in config directory, removed the container and created a new one. Have been having this problem ever since. I dont think rwx is an issue because once Im in the container, I cant even ls the config directory. What can explain that?

I can try running as host first and see if that works. Anything else I could try? Can I get more information generated in the logs?

pl_5309 · August 27, 2019, 4:18pm

In your run file do you have?

PLEX_UID=1000 \
PLEX_GID=100 \

And was your user added to the docker group?

sansadk · August 27, 2019, 6:13pm

Yes. My user “santosh” belongs to docker group. I didnt use PLEX_UID and PLEX_GID since the directory outside the container belongs to UID=1000 and GID=1000 and within the container plex user seems to have the same UID and GID. You think that might be the issue? Why 100? Ill try that out today.

Setting GID to 100 doesnt seem right based on above. So I even tried 1000, that had the same result. So back to square 1

Found the problem. This is a selinux issue which was preventing access to the directory. Whats the cleanest way to avoid this. I temporarily disabled selinux to get past this.

sansadk · August 28, 2019, 6:26am

Is using the Z option the best thing here?

Thanks!
