What are Microservices?
“In short, the microservice architectural style
is an approach to developing a single
application as a suite of small services,
each running in its own process and
communicating with lightweight mechanisms,
often an HTTP resource API.“
-James Lewis & Martin Fowler

config.vm.define "productservice" do |ms|
ms.vm.provider "docker" do |d|
d.build_dir = "./product-service/"
d.ports = ["9001:9001","7979:7979"]
d.link "eureka-master:eureka-master"
d.has_ssh = false
end
end
