Consul

This directory contains a docker-compose environment that demonstrates how to use the consul service discovery back-end with linkerd. It deploys the demonstration environment in a service-to-linker configuration

The following components make up the system:

• curl which acts as our client application
• linkerd for proxying requests to our service
• helloworld example service
• consul as our service discovery back-end
• consul-registrator to automatically registers services with consul
