Consul Service Discovery#

Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure. It’s often used as service discovery backend to register and locate the services composing your system. Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services can be registered as well.

This page explains how Stork can use Consul to handle the service discovery and service registration.
