Introduction 08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned recorded a podcast [1] to talk about tools in the Kubernetes space. Specifically, continuous integration (CI) and continuous delivery (CD) tooling. My mindset at the time was, “We can do better.” We received 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 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 GitOps The 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 consistent end to end workflows across your entire organization. Not only are your continuous integration and continuous deployment pipelines all driven by pull request, but your operations tasks are

approach to software delivery. Here are some of the key reasons: Manage deployments from on-premise to cloud to edge Scale infrastructure to meet demands Enable built-in compliance Enforce zero-trust security great example of an organization that needs to support legacy applications and extend them with cloud capabilities and modern practices like GitOps. The platform approach at Deutsche Telekom enables repeatable and reusable. This trait is especially useful when an application needs to be scaled at cloud burst speed. Being in the retail space, MediaMarktSaturn has many days of unusually high traffic
