This is an example of creating a micro function. A function is a one time executing service.

• main.go - is the main definition of the function
• proto - contains the protobuf definition of the API

Micro services need a discovery system so they can find each other. Micro uses consul by default but its easily swapped out with etcd, kubernetes, or various other systems. We'll run consul for convenience.

Install consul

brew install consul

Run Consul

consul agent -dev

go get github.com/micro/micro

micro run -r github.com/micro/examples/function

micro query go.micro.fnc.greeter Greeter.Hello '{"name": "john"}'
