DevOps with examples

by seomago Update: 29/5/2021

About the project

These is a list of self-study examples for my personal Devops roadmap learning path. DevOps is changing the way of developing web applications. We will be building several web applications using different technologies. We will be using debian distribution linux machines.

Getting started

We will use a Ghost blogging web application as an example but all the concepts are aplicable to any web application.

Simply clone the repository on a testing / dev / debian/ubuntu machine and follow the commands/ instructions. You will learn a lot with all these examples.
