/tmp not writable

[tscholak]

For some reason, /tmp stopped being writable within the plex container. Since this is where plex stores transcodes, videos couldn't be played. As a workaround, I made /tmp into a volume, i.e. I ran

docker run -d --net="host" --privileged="false" --name="plex" -v /path/to/plex/config:/config -v /path/to/video/files:/data -v /path/to/temporary/directory:/tmp needo/plex

Maybe I should mention that I'm running docker on Fedora 21 in SELinux mode enforcing. I also had to remove the link to /etc/localtime. Otherwise, docker-run would fail with System error: Relabeling content in /usr is not allowed.
