How to create a simple "http file not found" failover between two droplets in the same data center using floating IPs?
Trying to create fail-over between two droplets in the same data center using floating IP. The droplets are running NGINX with a module that's constantly generating a new status.html file. If there is a problem, status.html will no longer be produced and is automatically cleared. All that's needed for the the failover test, is if http://PrimaryDroplet/status.html is not found, then floating IP should route to http://BackupDroplet/status.html.
I am looking for the simplest way of implementing such a failover. I have already read the Floating IPs tutorial that references Corosync and Pacemaker, Keepalived and Heartbeat. Is there a SIMPLER way of implementing this scheme? Thanks.
