## What's new with GitOps and OpenShift Jonas Janz AppDev Solutions Architect https://github.com/pixeljonas ## What is GitOps? GitOps is when the infrastructure and/or application state is fully associated infrastructure and applications through automation. GitOps is a natural evolution of Agile and DevOps methodologies ## Why GitOps? It takes weeks (or months!) to provision an environment The version Production deployments have a very low success rate I can’t audit configuration changes ## GitOps Benefits • All changes are auditable - Standard roll-forward or backwards in the event of failure

## GitOps Continuous Delivery with Argo and Codefresh BRANDON PHILLIPS | CODEFRESH ## I nfo slide (not for presentation) Original Abstract: GitOps is the gold standard for managing and deploying Kubernetes of "GitOps" to take advantage of Kubernetes declarative infrastructure in order to deploy more often, and with more reliability. In this session, you'll learn the principles of GitOps and how the engineering process. New: GitOps Continuous Delivery with Argo and Codefresh Description: Never make a manual change again. In this talk we’ll show how to use GitOps to achieve reliable, and fast
