Specifically, continuous integration (CI) and continuous delivery (CD) tooling. My mindset at the time was, “We can do better.” We something you can buy off the shelf? Or is it just a fancy new term for DevOps [1.1], or continuous integration/continuous deployment (CI/CD) [1.2]? As a matter of fact, GitOps unifies a collection of different

The paradigm already existed in one form or another

by using Git as a source of truth for declarative infrastructure and applications. Automated CI/CD pipelines roll out changes to your infrastructure when commits are pushed and approved in Git. It also pieces together. Whatever you choose for your delivery pipeline, applying GitOps best practices with Git (or any version control) should be an integral component of your process. It will make building and of facts instead of by a set of instructions. With your application’s declarations versioned in Git, you have a single source of truth. Your apps can then be easily deployed and rolled back to and

infrastructure and/or application state is fully represented by the contents of a git repository. Any changes to the git repository are reflected in the corresponding state of the associated infrastructure minimizes or eliminates this need ● Declarations are yaml files which are easily stored and managed in git OpenShift GitOps Principles ● Separate application source code (Java/.Net/etc) from manifests (yaml) be applied with standard Openshift and k8s tooling Day 2 operations : All changes triggered from Git Tools of the Trade https://argoproj.github.io/argo-cd https://kustomize.io/ Argo CD Kustomize

• Configuration Management in Kubernetes • GitOps for Kubernetes Essentials • Conclusion Git is the most widely used version control system, with more than 80 percent of its market share in today’s software industry. GitOps is a methodology which revolves around procedure and practices with Git at the center. It provides a fast and secure method for developers to maintain and update complex infrastructure and application configuration changes revolve around Git, i.e., the version control ecosystem. The focus is entirely on keeping Git as a single source of truth for infrastructure and application

to streamline and automate the deployment and management of applications and infrastructure using Git as the single source of truth. It simplifies and standardizes the deployment and management of complex where managing infrastructure as code is crucial. Essential elements of GitOps include continuous integration / continuous delivery (CI/CD), choosing between pull- or push-based architecture, and observability In-Depth Introduction to GitOps? Learn the differences between GitOps and DevOps, and how to ensure Git is the single source of truth for your application in our free Understanding GitOps guide. DOWNLOAD

custom configuration on top of simple setup With requirements such as: ● Multicluster ● GitOps integration These are not just specific requirements. They help you understand Istio offerings more in ● All changes are driven by Git repo This demo uses Argo CD. Benefits are: ● Git repo becomes source of truth ● Clear change history ● Pull Request approval flow ● Non-Git based changes get reverted

building is Git. Git is widely used in software delivery, and its success is the reason why platforms like GitHub and GitLab are household names in every software delivery team today. Git has led to the GitOps - The way to build internal platforms GitOps views Git as the single source of truth. The entire system needs to be declared in Git and any changes are initiated using a simple pull request. GitOps allows you to create and manage your entire software stack through Git and treat your servers as your source code. Every change and configuration is done through a pull request and everyone
