During this presentation we are going to explore the GitOps concept and apply it with a tool called ArgoCD (https://github.com/argoproj/argo-cd). We will try to discover how this GitOps concept was born, what made it possible in the Kubernetes world and why it has become so popular. ArgoCD is a well known tool in the GitOps world, it is a CNCF project and it was featured on the Trial quadrant in the Thoughtworks Radar last year (https://www.thoughtworks.com/radar/platforms/argo-cd). We will demo some of its main features that make it so powerful and easy to adopt. At Mambu we are using it since 2018 and we have been in production with it for more than 2 years.
