In this tutorial, we'll show you how to obtain a file's complete path in Linux. ... Read More

Introduction When it comes to getting started, maintaining efficiency and velocity, or improving team performance, Version Control Systems (VCS) can be a fundamental component for DevOps teams. As well as supporting the mechanical actions required by DevOps – tracking changes, documenting changes, merging data, and more – an effective VCS must also support the needs of the developers – intuitive command syntax, visibility into changes, etc. - since it is constantly used by developers.  During the past decade, distributed VCS has gained widespread popularity, where copies of a single source of truth repository are shared - or cloned - out ...

Introduction The GitOps methodology organizes and maintains the infrastructure for a project. By pushing a change to source control, a git commit triggers an update to cloud infrastructure or applications. In GitOps, changes in Git trigger builds and deployments of infrastructure and applications, so Git is the only source of truth. It is common for companies to use GitOps in conjunction with Kubernetes as their container orchestration platform. In this article, we will explore Gitops in detail and why we need to use them What is GitOps GitOps is a subdiscipline of DevOps with similar aims, including speed and efficiency. ... Read More

Introduction Bare repositories are the same as default, but they cannot be committed to. Bare repositories do not have a working tree, so they cannot track changes made to projects. All project files/subdirectories are stored in a working tree. All project files are stored in a specific folder within the bare repository, which is basically a .git folder. In this article, we will explore more about bare repositories What is Git Repository A Git repository contains a collection of files and folders that track the history of your codebase's changes.

If we're going to use a NoSQL DB for our app, then we want something fast and easy to use. We learn that "NoSQL" doesn't necessarily imply "no maintenance". We think about using managed hosting services like MongoDB's Atlas or Amazon's DynamoDB, but we choose to host it ourselves, whether on our premises or in our own cloud instance. We evaluate several NoSQL options including Redis and Cassandra and pick MongoDB. We may be able to get it installed by installing it from our Linux distribution, using Mongo’s repositories, or using a snap. But if something goes wrong, we might ... Read More
