Yes ... but for me it didn't work from the GUI. so I did this command (via ssh) manually:
docker pull binhex/arch-rtorrentvpn:rtorrent-ps-1.1.r54.ga787dd9-1-30
This version works fine for me, didn't bother to try higher version.
PS .. sorry I reply so late ... didn't get any notification
What tag do I need to use for Synology (DS916+ with DSM 6.2.3-25426 Update 3) because it's not clear to me.
I got this message with the latests version: FATAL: kernel too old
