What's new with GitOps and OpenShift 1 Jonas Janz AppDev Solutions Architect https://github.com/pixeljonas 2 GitOps is when the infrastructure and/or application state is fully represented by 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 an environment “reapply the current state of the manifests” ● Experience is “pushes and pull-requests” GitOps Benefits 5 GitOps is for Everyone Developers Operations Kubernetes Cluster Node 1 Kubernetes (K8s) is

GITOPS EXPLAINED: CONCEPTS, BENEFITS & GETTING STARTED DevOps has changed the way we develop and manage applications, resulting in faster, more consistent, more collaborative development cycles. It has a new kind of Ops. GitOps is rapidly gaining popularity to extend the scope of DevOps further to include application infrastructure. In this article, we will have a look at GitOps and how to leverage leverage it for delivering cloud-native applications. What is GitOps? GitOps is a set of practices that are aimed at managing the underlying infrastructure of an application. It utilizes Git as the source code
