I added a prelimnary WIP verion of the docker-containers on github: [https://github.com/kopfpilot/docker-plex-prt](https://github.com/kopfpilot/docker-plex-prt) though, slaves don’t register at the master yet. For time beeing plex 0.9.96.6 is preinstalled and pinned to the version unsing the ENV VERSION, which can be overridden by adding -e VERSION= to your create or run cmd or the docker-compose.yml. I still try to access ssh without the unknown host notification. Once this is solved, i will make the client self adding itself to the master. See the Dockerfiles/ docker-compose.yml for needed volumes mapping and ports to expose. Slaves will reuse the volumes from the master-container, if you use “volumes-from”. Otherweise you have to take care of the volumes mapping yourself. The Image is not uploded to dockerhub yet - which i plan to do, once i am ready. Means you have build it yourself. build docker images: docker-compose build run containers: docker-compose up -d That’s what i could come up with the few hours i had the last past days. Mounting the shares is ment to happen on the docker host level. ---

Yes I will soon. Another question here. My Plex Database is growing none stop since I upgraded PMS to version 1 évent is thumbnail option is set to off. Have you seen the samethingg on your installation. ? **EDIT: Okay nstead of using ubuntu 14.04 I tried with a ubuntu server 16.04 and the PRT SESSION option is working fine. psutil version is different on that ubuntu version python -c “import psutil; print psutil.version\_info” (3, 4, 2)** ---

If you look at your system messages by using dmesg do you have a few lines like this **plex\_transcoder[82410]: segfault at 0 ip 00000000005f8108 sp** I’m not experiencing any issue but I’m just curious.
