Jellyfin Docker Swarm stack that allows for fault tollerant rffmpeg.

  NOTE: This isn't fully functioning at this time - Do not use

Host System Assumptions:

• Intel QSV CPU
• Debian or Ubuntu
• Intel specific setup is followed including fixing all limitations of various kernels

  https://jellyfin.org/docs/general/administration/hardware-acceleration/intel#linux-setups
  

• Low Power Mode is setup

  https://jellyfin.org/docs/general/administration/hardware-acceleration/intel#lp-mode-hardware-support
  

• OpenCL is installed

  intel-opencl-icd
  

• NFS/NFSD is installed

  sudo apt install nfs-common
  sudo apt install nfs-server
  sudo sh -c "echo 'nfsd' >> /etc/modules"
  sudo sh -c "echo 'nfs' >> /etc/modules"
  sudo modprobe nfsd nfs
  

• Apparmor is removed

  sudo systemctl stop apparmor.service
  sudo systemctl disable apparmor.service
  sudo apt purge apparmor
  

• Directory /transcodes exists with group ownership to users

  mkdir /transcodes
  chgrp users /transcodes  
  

• SSD with enough space to handle transcodes
• Docker swarm is already setup and running
• Nodes are running a local container that allows for device mapping within swarm

  Original:
  docker run -i --restart always -d --name device-manager --privileged --cgroupns=host --pid=host --userns=host -v /sys:/host/sys -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/allfro/allfro/device-mapping-manager:latest
  
  Note: the below includes a fix that will map devices for containers already running.
  docker run -i --restart always -d --name device-manager --privileged --cgroupns=host --pid=host --userns=host -v /sys:/host/sys -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/gitdeath/device-mapping-manager:master
  

• Nodes within the swarm that meet all assumptions have a label 'transcode' with a value of '1'
