Migrating Emby from Diskstation package to Docker Container

gotchas.md

• Tranmission OpenVPN has a funny setup - requires a TUN.sh to be setup to enable the VPN tunnel
• If ports become unmappable in the silly Docker UI on Synology, refer to this note about /user/local/etc/services.d files - https://forum.synology.com/enu/viewtopic.php?t=86531#p326803

update.md

• Getting Sonarr running - https://www.naschenweng.info/2016/11/04/synology-docker-sonarr/
• Getting Radarr running - https://drfrankenstein.co.uk/2017/03/28/setting-up-radarr-in-docker-on-a-synology-nas/

There are some docs in Emby about a couple of approaches at https://github.com/MediaBrowser/Wiki/wiki/Backup

However, you can also do things the hard way! (Some info at https://emby.media/community/index.php?/topic/60079-relocate-media-library-metadata/)

• Update the optional path in Emby itself from \\serverfoo\path\to\files to \\serverbar\path\to\files to make sure native paths still work in Emby

Use a tool like SQLite Web container at https://hub.docker.com/r/coleifer/sqlite-web/ to mount library.db and run a query like

UPDATE "TypedBaseItems" 
SET Path = replace(Path, '/var/packages/EmbyServer/target/var', '/config') 
WHERE Path is not null 
  AND PATH LIKE '%/var/packages/EmbyServer/target/var/%'

Launching Transmisssion

• Requires a TUN script to be setup (and run as a task every 5 minutes)

#!/bin/sh

# Create the necessary file structure for /dev/net/tun
if ( [ ! -c /dev/net/tun ] ); then
  if ( [ ! -d /dev/net ] ); then
    mkdir -m 755 /dev/net
  fi
  mknod /dev/net/tun c 10 200
  chmod 0755 /dev/net/tun
fi

# Load the tun module if not already loaded
if ( !(lsmod | grep -q "^tun\s") ); then
  insmod /lib/modules/tun.ko
fi

• Requires the root@Molokai:/volume1/docker/transmissiondata# ./docker-run.sh command to be run that consists of:

#!/bin/sh

docker run \
  --cap-add=NET_ADMIN \
  --device=/dev/net/tun \
  -d \
  -v /volume1/docker/transmissiondata/resolv.conf:/etc/resolv.conf \
  -v /volume1/docker/transmissiondata/AirVPN_America_UDP-443.ovpn:/etc/openvpn/custom/default.ovpn \
  -v /volume1/Media/Downloads/Transmission:/volume1/Media/Downloads/Transmission \
  --env-file /volume1/docker/transmissiondata/DockerEnv \
  -p 8888:8888 \
  -p 9091:9091 \
  --sysctl net.ipv6.conf.all.disable_ipv6=0 \
  --name "transmission-openvpn-syno" \
  haugene/transmission-openvpn:latest

Keep in mind there is a DockerEnv file at /volume1/docker/transmissiondata/DockerEnv based on https://github.com/haugene/docker-transmission-openvpn/blob/master/DockerEnv

• create all relevant users (old packages use these scripts -> https://github.com/SynoCommunity/spksrc/blob/51979b1296561d40127db313873bfaf46bec200d/mk/spksrc.service.installer)
