Docker Cluster/Fail over Manager for unRaid

I want to build a set of unraid servers where my VM's and dockers have an HA host to fail back to. I need something to start and start VM's on Unraid2 if Unraid1 goes down. I also need it to keep Unraid1 from starting applications and VM's that are running on unraid2.

Currently I have a qnap box that I got from work that I am thinking about turning into my repo for shared storage for this purpose. It's not perfect and I might load Ubuntu over the top of it because the QNAP software is crap. It's a TS-932x with the Annapurna chip in it and 10Gbe out the back.

Is there a tool that already exists that can do what I want? I understand I'd need a 3rd server (UnraidCM) to act as HA Manager for this to function.

 

This could be a 3rd party tool, a first party app or part of the unraid OS.

Maybe this would be something to look into for a plugin or the next major release?

Some kind of clustering would be interesting although i would prefer a form of replication for disaster recovery.
if it was possible to replicate the apps/VM configuration and data linked to it (also binds for docker) it would be great.
If it would automatically turn on the apps/vm's on the slave node when the master is down it would be even better, this would decrease downtime and make the software a little more interesting for small businesses that need a form of disaster recovery for their services.

would love to see this as a feature

Ya I'm struggling with not wanting to run another type of VM host. I already have docker swarm cluster for fail-over and need a fail-over supported VM setup. Add this too the list as this is my number #1 as I already have two unraid servers

So you're running unraid docker containers as part of a swarm? Is there anything special I would need to do compared a normal swarm?
