Dockerized Microservices
3 likes•1,652 views
The document discusses the concept of microservices, which involve developing applications as a suite of small, independent services that communicate via lightweight mechanisms. It also explores the advantages of microservices such as scalability and fault tolerance, while clarifying that they come with runtime overhead. Furthermore, it details how to dockerize these microservices utilizing examples and orchestration tools like Vagrant.
![Vagrant
Vagrant.configure(“2”) do |config|
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
