A microservices example: writing a simple to-do application

Microservices are becoming a new trend, thanks to the modularity and granularity they provide on top of advantages like releasing applications in a continuous manner. There are various platforms and projects that are rising which aims to make writing and managing microservices easy.

Keeping that in mind, I thought, why not make a demo application that can give an example of how microservices are built and how they interact. In this article, I will be building a small application using the Microservice Architecture (MSA).

The application will be a super simple To-Do management list. So, let’s have take a look at what we are going to build and how we are going to build.

Editor’s note: This article references Fedora, which is the upstream project for Red Hat Enterprise Linux (RHEL) — now free for developers. This tutorial should also work on RHEL, just replace ‘dnf’ with ‘yum’ wherever appropriate.

Provisioning Vagrant boxes using Ansible

Ansible serves as a great tool for those system administrators who are trying to automate the task of system administration. From automating the task of configuration management to provisioning and managing containers for application deployments, Ansible makes it easy. In this article, we will see how we can use Ansible to provision Vagrant boxes.

So, what exactly is a Vagrant box? In simple terms, we can think of a vagrant box as a virtual machine prepackaged with the development tools we require to run our development environment. We can use these boxes to distribute the development environment which the other team members can use to work on the projects. Using Ansible, we can automate the task of provisioning the Vagrant boxes with our development packages. So, let’s see how we can do this.

For this tutorial, I am using Fedora 24 as my host system and Ubuntu 14.04 (Trusty) as my Vagrant box.

Editor’s note: If you want to run get started with Vagrant to provision or build containers using Red Hat Enterprise Linux with just a few clicks, check out the Red Hat Container Development Kit.
