 ======Docker Deluge Image / Service======
 I want a torrent service that uses a VPN and is set-up to block non VPN WAN (internet) access.  On my virtual machine implementation of this I used the following 3 packages: deluge (deluged with deluge-web), openvpn and nftables.  I have used both iptables and nftables and find nftables is definitely more elegant to use.  As far as I can tell there is not a Docker image that will meet my needs.

 I have been successfully been running this in a container on my home server since early 2023.  This replaced the a similar setup that have I been operating since about 2017 on a virtual machine using Linux KVM/Libvirt/QEMU.
-=====s6 supervision rc system=====
-I decided to build this container image based upon Alpine Linux using the [[https://www.skarnet.org/software/s6/index.html|S6]] init system. The Skarnet.org is the S6 authors web site and main repository.
-S6 [[http://www.skarnet.org/software/s6/servicedir.html|Service directories]]
-++++Basic S6 commands:|
-  *''s6-svstat /run/service/servicename'' or ''s6-svstat /run/s6-rc/servicedirs/deluged'' - check a daemon status, longrun only!
-  *''s6-rc -u change servicename'' - enable and start a daemon (up)
-  *''s6-rc -d change servicename'' - disable and stop a daemon (down)
-  *''s6-rc-db list all|services|oneshots|longruns|bundles'' - lists the nominated services in the active s6-rc-db
-  *''s6-rc-db type servicename'' - Prints the type of servicename: oneshot, longrun or bundle
-  *''s6-rc-db dependencies servicename'' - lists the dependencies in the servicename directory, i.e. in servicesname/dependencies.d
-  *''s6-rc-db dependencies servicename'' - lists all the dependencies of servicename
-  *''s6-rc-db -d|-u timeout servicename'' - lists the timeout, -d for timeout down and -u for timeout up
-BTW dont spell dependencies as dependencies and wonder why things don't work, lol the English language sucks.
