Just like Kubernetes, Argo is deploying and winning everywhere, in the datacenter, behind the firewall, and at the edge. In our experience, we’ve seen every kind of deployment imaginable (and some that would truly surprise you) and we’ll share patterns for success along with what we’re doing to keep Argo working securely in all these diverse use cases.

As organizations increasingly adopt GitOps and infrastructure-as-code, accurately visualizing manifest changes before they merge has become crucial. Mentally parsing Helm templates and Kustomize patches is too unreliable for catching configuration errors. Join us as we review the current landscape of tools and methods used for visualizing code changes in Argo CD, highlight their limitations, and introduce a new method that leverages ephemeral clusters and Argo CD to render accurate diffs of Helm Charts and Kustomize overlays directly on pull requests. The presentation showcases a tool illustrating this new approach and discusses its overall design. We will demonstrate how the approach can be seamlessly integrated into CI/CD pipelines to prevent deployment errors and streamline code reviews, all without access to live infrastructure. Finally, we’ll conclude with an honest assessment of the method’s capabilities and limitations and discuss potential areas for future development.

With the right setup, you can bootstrap everything using Argo CD and good GitOps practices. With that power comes the ability to delete everything at once too! In this talk we’ll do a deep dive into how app deletion works in Argo CD and real scenarios on how teams have accidentally deleted a lot more than they planned. In the worst cases, items permanently stuck in deletion can prevent recovery. We’ll set finalizers, change deletion propagation and break the application set controller to create cascading failures and, better yet, show you how to avoid accidents. Every admin and Argo CD user should attend this talk.

Are you tired of looking at metrics and logs after each deployment? Do you learn about failed deployments from unhappy customers? Did you always want to deploy on Friday afternoon and go straight to the pub? Many teams perform “blind” deployments without any real insight into what will be affected by the new application version. Consequently, they don’t have enough data to understand the blast radius of a release and whether to decide if it was successful or not. Even companies that have several metrics in place, don’t always use them in an automated manner. Wouldn’t it be great if you could see user behavior with new features in real time and identify performance bottlenecks before a full release? In this talk, we will focus on common scenarios regarding Argo Rollouts and observability metrics, we will explain: – Minimum requirements in terms of tools and metrics/traces/logs – Well-known observability use cases – Common automation pitfalls – RED/USE metrics tradeoffs
