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

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

It enhances server and cloud computing features, and incorporates key technologies including cloud-native CPU scheduling algorithms for hybrid service deployments and KubeOS for containers.

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.

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

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
