Hello. Is it possible to setup HA with 2 master nodes ?
I need to achieve a setup, that second node would work only as standby until first node for any reason goes down. These would be Raspberry PI machines and no other hardware should be needed, so solution should include both (master replication and load balancer). In other words, all deployed services should work at time on one node only, load balancer should route the traffic only to that node and when node is off or services are crashing on that node, everything should be spawned on second node and load balance should route traffic to second one. Is it possible ?
