Morning everyone, I'm looking for emergency shutdown advice - we've an APC UPS that I can configure to shutdown servers and start them in an emergency, we've about 40 mins power coverage for our cluster - 3 node rancher management cluster managing a 5 node harvester setup and the clusters deployed on it. My question is - is this something we simply have to install on each host manually, or is there a "Rancher" way to hook up the UPS? Basically - when the power just goes we've seen drive fails and data corruption, even if we add a generator to the building we need to deal with the edge case of power not being available - hence a controlled shutdown may be needed so looking at how best to achieve this. Any advice greatly appreciated!
