Welcome to our 40th meetup, now online, about DevOps values, practices, and culture.

Kubernetes Stairway To Production is a new series dedicated to the knowledge, practices, and techniques build around the Kubernetes platform. We will provide more information about this series in the near future.

Meanwhile, the first topic that we will approach is GitOps.

GitOps is a paradigm or a set of practices that empowers developers to perform tasks that typically (only) fall under the purview of operations. It’s a way to do Kubernetes cluster management and application delivery by using Git as a single source of truth for declarative infrastructure and applications.

Being Git at the center of delivery pipelines, engineers use familiar tools to make pull requests to accelerate and simplify both application deployments and operations tasks to Kubernetes.

GitOps software agents (e.g. ArgoCD and FluxCD) can alert on any divergence between Git with what's running in a cluster, and if there's a difference, Kubernetes reconcilers automatically update or rollback the cluster depending on the case.

In this talk, our invited speakers Remi and Ricardo, will highlight the main principles of GitOps and include demos of ArgoCD and FluxCD on how to configure and use it to accelerate and simplify application deployments.
