This documentation describes installing, configuring, and using the a9s Consul DNS for Pivotal Cloud Foundry (PCF) tile.
The a9s Consul DNS for PCF tile provides a highly available DNS service including a Consul cluster as well as additional Dnsmasq servers for service discovery and service failover procedures.
Consul is a highly available (HA) service discovery and configuration tool, which includes features such as failure detection, an HA key/value store, and an HA DNS service that you can control through a HTTP-based REST interface.
