With the growing maturity of the Kubernetes Gateway API and the Argo Rollouts plugin for Gateway API, it's now easier than ever to integrate Argo Rollouts with any traffic provider that implements the Gateway API. This allows you to automate progressive delivery decisions based on custom HTTP metrics. While most traffic providers focus on north-south traffic, some now offer seamless support for both north-south and east-west traffic patterns.

In this demo-driven session, we’ll explore how to use Argo Rollouts and the Kubernetes Gateway API to control traffic for both north-south and east-west directions without requiring application restarts. By leveraging Istio Ambient Mesh and HTTP metrics, we’ll dynamically monitor application health to drive progressive delivery decisions.

One of the most exciting recent enhancements to Argo CD is native OCI (Open Container Initiative) integration support. No longer are you limited to Git or Helm as a storage backend, but Argo CD now natively integrates with a piece of infrastructure you already have available: an OCI registry. And the best part: all of your existing Argo CD content can be reused in a brand new way!

Join members of the Argo CD community that brought native OCI integration to life in this panel session as they share everything that you need to know to effectively take advantage of this new capability.

In particular, they will discuss:

* The development process and community collaboration involved
* The technical details associated with native OCI integration in Argo CD
* The business value and how it unlocks the benefits of Argo CD like never before
* Common methods for managing OCI content including integration into existing workflows
* Examples that you can use to get started in your own environment

Argo Rollouts is a Kubernetes controller for Progressive Delivery deployments. In the most basic scenario, Argo Rollouts supports advanced Kubernetes deployments such as blue/green and canaries. While this is great, the main selling point of a Kubernetes cluster is the autoscaling facilities it offers. Can you use canary deployments while still taking advantage of Horizontal (and Vertical) autoscalers?

The answer is yes! In this talk, we will see how you can combine these two worlds - progressive delivery and autoscaling - and explain how to perform advanced deployments even in the presence of autoscalers.

If you’re running a multicluster environment—and really, who isn’t?—you can face challenges scaling deployments across your fleet no matter how big. Agent-based solutions can often be the best option to solve this.

The Argo CD Agent is a lightweight solution that helps Argo CD deployments scale more easily. The agent is quite notable in that it doesn’t require a permanent network connection and is lightweight and extensible allowing workload clusters to stay autonomous. In this session we will take a technical deep dive into the agent architecture.

We will demonstrate how to deploy the agent using the implementation of the Sig-Multicluster specification found in the Open Cluster Manager (OCM-io) project. Using OCM-io’s Add-on framework and the Argo CD Agent you’ll see how these two community tools and open standards help you with managing your GitOps at scale more reliably.

If you are starting out on your Argo Workflows journey, you’ll soon find yourself surrounded by the word ‘template’. Templates are a fundamental cornerstone of an Argo Workflow and allow you to define the work to be performed.

In this talk, we'll explore the versatile world of Argo Workflow template types. We'll break down the different types, demystifying their use cases and best practices. While container templates are widely used and referenced in the documentation, we'll delve into the lesser-known but equally powerful template types such as the http template, container sets and resource templates.

Along the way, we’ll also tackle common misconceptions - including the surprising difference between a workflowTemplate and a Workflow Template.

Whether you’re a seasoned professional or new to the world of Argo Workflows, expect to leave with a deeper understanding of Workflow Templates - ready to apply their versatility and power to solve complex workflow challenges.

You probably have more than one cluster and there is a decent chance you are using Argo CD. Additionally, it is quite likely that you have a few other variations of Kubernetes cluster lists. We posit that writing glue code to stitch together these clusters lists is not an awesome use of your time. Thankfully the good folks in SIG-Multicluster built this super cool api for cluster lists, cluster profile/cluster inventory! We are going to show you how to use said fancy new list with Argo CD along with other multi-cluster tools across Kubernetes clusters hosted by different providers. There will be demos. Possibly Mustaches. And a decent amount of awful puns. So come on down to bear witness to some sweet multi-cluster abstractions that will surely get your heart rate up.

As companies expand their usage of Argo CD and its powerful UI, robust security in multi-tenant environments becomes critical. Thus, misconfiguring Argo CD can lead to significant security vulnerabilities.

This session will provide a technical deep dive into securing Argo CD installations for multi-tenant environments. We’ll examine the building blocks for establishing effective security controls—like Application Projects, security policies, and user roles—and highlight best practices for defining access controls using Argo CD’s RBAC policies, and restricting deployments to specific clusters and namespaces and structuring Application Projects.

Through real-world examples, Argo CD admins will learn to configure their installations securely, manage permissions, and tailor the environment to meet organizational needs without compromising usability or productivity. The talk will also provide practical strategies to avoid common pitfalls in permission management.

Time series data is exploding across industries - from IoT sensors and financial markets to application monitoring and user behavior analytics. As organizations grapple with processing these massive datasets, many overlook a powerful solution hiding in plain sight: Argo Workflows. This talk demonstrates how Argo Workflows transforms time series analysis from a resource-intensive challenge into a streamlined, scalable process in Kubernetes environments.

We'll dive deep into real-world architectures that leverage Argo Workflows' DAG-based execution model for efficient time series processing. You'll learn practical patterns for data partitioning, parallel processing, and resource optimization that we've battle-tested with petabyte-scale datasets. Through live demos and code examples, we'll explore how to build resilient pipelines that can handle everything from real-time sensor data to historical trend analysis.

Workflow specs can be pretty complicated, involving references to many different templates and WorkflowTemplates with nested container or script definitions. Outside of using argo lint, how do you make sure your complicated Workflow definition is valid and legit? The community has raised similar questions/concerns in Issue #13503.

In this talk, we'd like to share how we utilize Kubernetes' Validating Webhooks and Argo Workflow's validating function to address this concern to make sure every Argo Workflow resource submitted into our system not only uses valid specifications, but also references valid templates with the correct parameters.

As WebAssembly (WASM) and serverless technologies like SpinKube gain traction, they introduce new paradigms for lightweight, fast, and secure application deployments. However, the unique characteristics of SpinKube/WASM applications—such as custom resource definitions (CRDs) and unconventional health signals—pose challenges for Continuous Delivery.

In this talk, we’ll explore how to leverage ArgoCD to seamlessly deliver SpinKube-based WASM applications. We will demonstrate how ArgoCD’s built-in and custom health checks can monitor resource health, ensure smooth deployments, and surface critical insights for SpinKube workloads. Key takeaways include:

- How to integrate SpinKube/WASM applications with ArgoCD for Continuous Delivery.
- Practical examples of creating custom health checks for CRDs or non-standard resource types

Join us to discover how combining SpinKube and ArgoCD simplifies and scales Continuous Delivery for next-generation serverless applications.

We’ve learned to think of environment promotion in terms of deployment pipelines. But in the age of Kubernetes and everything-declarative, we need to abandon the imperative pipeline mode of thinking. According to the Kubernetes model, environment state should be declared, and an operator ought to drive towards that state. To achieve this, we need GitOps Promoter and its CommitStatus API.

GitOps Promoter is a new environment promotion tool that adheres strictly to GitOps principles. Promotions are handled through automated PRs, and promotion gates are implemented as commit statuses. This talk will demonstrate how to use the GitOps Promoter’s CommitStatus API to gate promotions on Argo CD application health. We’ll show how the only prerequisite to enabling a fully declarative GitOps promotion experience is “having an opinion about a commit.”
