can be traced back to February 2001, when the Agile Manifesto [1.3] was published. In many ways, the Agile Manifesto is the grandfather of DevOps. Agile development practices were a big step toward improving application development process for the end user and for internal or external customers. However, while Agile focused on customer and developer experience, the process of delivering that software was still stuck DevOps So if GitOps isn’t anything new, why are we hearing so much about it now? Much like how the Agile Manifesto changed the game for developers and administrators, Kuber- netes and other container technologies

associated infrastructure and applications through automation. GitOps is a natural evolution of Agile and DevOps methodologies What is GitOps? 3 Why GitOps? It takes weeks (or months!) to provision multiple purposes, leaving the original YAML untouched and usable as is. ● Kustomize is a patching framework ● Enables environment specific changes to be introduced without duplicating yaml unnecessarily since 1.14 ● Validates yaml before deployment Kustomize vs Helm vs OpenShift Templates Patching framework Ability to apply yaml directly Some use-cases may work better with templates No support in OpenShift

components 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 platforms because it has a set of strong defaults for versioning using Git repositories. The GitOps framework can greatly simplify and speed up the process of building and maintaining internal platforms. It
