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

late starter. KubeSphere is designed to integrate open-source projects and components in the cloud-native ecosystem into a unified container platform product, ensuring consistent user experience in all Red Hat's commercial software solutions or large enterprises that have very high demands for cloud-native security. OpenShift Functional Architecture 1.3.3 Rancher 15 Rancher products are very lightweight Kubernetes and cloud-native ecological projects. Since its products bring a high learning curve, Rancher is suitable for Kubernetes cluster O&M personnel who have a basic understanding of cloud-native technology

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

second project to ever join CNCF and the de facto standard in cloud-native monitoring Kubelets, sidecars, microservices, ALL the cloud-native But it’s a monolithic application ...why? Richard Hartmann issues Some bugs and some human mistakes in the release process Always running latest is the cloud-native approach, but this is still not acceptable ..especially if every single version has its issues
