08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned very positive feedback and later became a recurring show. Eventually, this work led us to the Cloud Native Computing Foundation’s GitOps Working Group (and later the OpenGitOps project). By then, GitOps 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

is a way to do Continuous Delivery. More specifically, it is an operating model for building Cloud Native applications that unifies Deployment, Monitoring and Management. It works by using Git as a source entire system is described declaratively. Kubernetes is just one example of many modern cloud native tools that are “declarative” and that can be treated as code. Declarative means that configuration on any server or public cloud. Weaveworks also contributes to several open source projects, including Weave Scope, Weave Flux and eksctl. It was one of the first members of the Cloud Native Computing

Introduction GitOps has gained popularity in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code 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

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 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

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 developed positive effect is not limited to the performance of engineering teams. Technology, in particular cloud native technology like Kubernetes and its ecosystem of projects, is now a core competency for organizations practices and operating models for managing cloud native technologies that together make the promise of DevOps easier to realize. Created for a cloud-native world, GitOps makes developers more productive

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 development platform that spans environments with security guardrails and a common set of cloud- native patterns, like secrets management, in place that any development team can deploy to and from.
