Introduction 08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned stored and versioned in Git, and by taking advantage of declarative configurations in Kubernetes. Cloud-Native DevOps So if GitOps isn’t anything new, why are we hearing so much about it now? Much like how technologies have changed the game for DevOps practi- tioners. The ways in which Kubernetes and cloud-native systems manage immutable instances (containers) have allowed DevOps practitioners to further

are property of their respective companies. Introduction GitOps has gained popularity in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code teams, and increases the reliability and reproducibility of deployments. GitOps is popular in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code enforces that desired state. GitOps takes DevOps practices and puts them into action for managing cloud-native workloads. The Philosophy of GitOps GitOps automates application code deployments and infrastructure

297 REFCARD | SEPTEMBER 2022 GitOps for Kubernetes Essentials to Applications Hosted in Cloud-Native Ecosystems NINAD DESAI STAFF ENGINEER, INFRACLOUD CONTENTS • About GitOps for Kubernetes dive into what GitOps means in the Kubernetes world, key principles, and the advantages for cloud-native ecosystems. ABOUT GITOPS FOR KUBERNETES Thanks to the DevOps movement, the focus on and responsibilities and tweaks would be taken care of by an automated mechanism. Since Kubernetes and many other cloud-native technologies are almost entirely declarative, infrastructure definitions can be kept alongside

with bureaucracy and legacy systems to one that is founded on open source software and modern cloud-native practices. Along the way, they have kept DevSecOps as their top priority. To make this transformation the ecosystem of available cloud-native open source projects in order to remain innovative and improve their time to market. However, they needed to implement cloud-native technologies within their highly Engineer, MMS Weave GitOps for internal platform building An internal platform is vital for modern cloud-native operations. The days of standing up infrastructure, and then maintaining it for years at a time

can find the operations side tricky when they’re trying to spin up infrastructure on modern, cloud-native technologies. They need a way to confidently and securely deploy changes to Kubernetes that doesn’t according to the four following principles: Kubernetes is just one example of many modern, cloud-native tools that are declarative and can be treated as code. The system’s entire infrastructure must

Performance: The Facts How GitOps Boosts Business Performance: The Facts 2 INTRODUCTION As cloud-native applications have become more prevalent, the concept of DevOps has changed the way software is native technologies that together make the promise of DevOps easier to realize. Created for a cloud-native world, GitOps makes developers more productive while improving application stability, security

infrastructure. In this article, we will have a look at GitOps and how to leverage it for delivering cloud-native applications. What is GitOps? GitOps is a set of practices that are aimed at managing the underlying
