This gist provides a way to automatically move an associated Elastic IP between nodes of a cluster in case of failover. This is because the standard VIP infrastructure provided by VRRP is not necessarily transparently compatible with Ravello's public IP/NAT routing, so the private VIP is not routable.
- As explained in Ravello's Blog, configure a couple of Highly Available Load Balancers using Keepalived (check this blog article if in doubt).
- Make sure to enable cloud-init on the VM and configure your VM to export the environment variables described below according to your setup.
