Defining SLOs and SLIs for ArgoCD: A Metrics-Driven Approach To Observability - Eve Ben Ezra & Serhiy Martynenko, The New York Times

Tuesday April 1, 2025 10:40 - 11:05 BST

Level 1 | Hall Entrance S10 | Room A

ArgoCD offers an extensive set of metrics that provide invaluable insights into its health and performance. However, as of now, there are no standardized guidelines or recommendations for defining Service Level Objectives (SLOs) or Service Level Indicators (SLIs) for ArgoCD. SLOs serve as a critical foundation for ensuring the reliability and quality of ArgoCD services, guiding teams to proactively address issues before they impact users.

In this talk, we will:
- Explore the wealth of metrics provided by ArgoCD components (API server, application controller, repo server, and more).
What is an SLO / SLI
- Propose actionable SLOs and SLIs tailored to ArgoCD operations, such as deployment success rates, reconciliation time, and resource health checks.
- Demonstrate how these SLOs can help identify early signs of service degradation, enabling teams to maintain high service quality.

Tuesday April 1, 2025 12:55 - 13:20 BST

Level 1 | Hall Entrance S10 | Room A

Argo CD has unlocked a GitOps revolution for deploying and keeping our applications synced. The next big problem to be solved is how to manage promoting changes between environments. CI-driven updates, Image Updater, Progressive Sync, Kargo, Environment and Promotions, and Rendered Manifest Pattern all propose different ways to tackle the basic problem of how to get changes from one environment into another.

In this talk, we’ll review the current state of application promotion across environments and how the different approaches work with pitfalls and benefits. To keep it honest, DevOps grump and professional detractor Viktor Farcic will bring his honest take as we look at the seemingly endless nuances of environment promotion and change management.

One Engine To Rule Them All: Unifying Cloud Workloads With Argo Workflows - Sebastian Beyvers, Giessen University

Tuesday April 1, 2025 13:30 - 13:55 BST

Level 1 | Hall Entrance S10 | Room A

Public cloud providers attract organizations with a promise: every computing service you need, neatly packaged under one roof. Yet those seeking to break free from vendor lock-in and build a sovereign infrastructure face a different reality - navigating a maze of specialized tools: Airflow for data pipelines, SLURM for HPC, Spark for analytics, and a variety of solutions for serverless functions - all using a different interface. We're here to challenge this fragmentation. What if Argo Workflows could be your universal scheduling engine? Through practical examples, we'll demonstrate how the Argo ecosystem - with its container-native workflow engine and robust event system - can consolidate most, if not all, of your compute infrastructure. We'll share our journey of integrating and/or replacing most of our existing scheduling systems with Argo, revealing concrete patterns that preserve workload-specific requirements while drastically simplifying our architecture.

Set It To Auto: Using Argo CD Autopilot To Simplify Everything

Tuesday April 1, 2025 14:40 - 15:05 BST

Level 1 | Hall Entrance S10 | Room A

How do you bootstrap Argo CD? Is it Terraform? Kubectl apply? Or have you set it to auto with Autopilot? Installing Argo CD to play around is easy but setting it up for a scalable, well-organized, and well-managed software delivery experience requires know-how and a bit of elbow grease. In this session, we’ll show how Argo CD Autopilot works and can serve as the basis for your GitOps pattern. This has benefits like easy disaster recovery, better user experience, more predictability in organization and adoption, and an overall streamlined experience.

But Autopilot is just the beginning! It’s easy to customize (with or without a K) and set up to do much more than what you get out of the box. Don’t reinvent the wheel, it’s time to use autopilot.

Scaling Argo CD: From Symptoms To Solution - Alexandre Gaudreault, Intuit

Tuesday April 1, 2025 15:20 - 15:45 BST

Level 1 | Hall Entrance S10 | Room A

Have you ever found yourself increasing the Argo CD controller CPU? Give it more memory? The answer is most likely yes, multiple times! But there comes a time when enough is enough. In this talk, we will go over as many scalability symptoms as possible, understand why they happen and how to mitigate them. You will learn that most of the time, increasing the resources is only a temporary fix. Our goal will be to dive deeper into each problem to find the underlying root cause, and apply a solution that addresses the problem at its source to have a lasting fix.
CPU consumption, reconciliation cycles, operation queues, cluster watches, monorepos and much more are on the agenda.

⚡ Lightning Talk: Extending Argo CD CLI Functionality With Plugin Support: Build Your Custom Plugins Now! - Nitish Kumar, Akuity

Tuesday April 1, 2025 15:50 - 16:00 BST

Level 1 | Hall Entrance S10 | Room A

The Argo CD CLI has been a cornerstone for managing GitOps workflows, but until now, it lacked support for extending its capabilities through plugins. This talk introduces plugin support to the ArgoCD CLI, enabling users to create custom plugins and use them as subcommands, extending the ArgoCD CLI functionality like kubectl.

In this talk, we’ll demonstrate the new plugin system’s real-world application by showcasing a plugin we developed: mta (Migrate to Argo CD). This plugin bridges the gap between Flux and Argo CD by exporting Flux components into Argo CD-compatible Custom Resources (CRs), simplifying migrations from Flux to Argo CD.

⚡ Lightning Talk: Mitigating Privilege Escalation in Multi-Tenant Argo CD - Anand Francis Joseph, Red Hat

Tuesday April 1, 2025 16:05 - 16:15 BST

Level 1 | Hall Entrance S10 | Room A

Argo CD supports a multi-tenant operation model. Cluster scoped Argo CD instance is the widely used approach wherein it uses a single service account to manage resources across multiple tenant namespaces and this brings in the security challenge of privilege escalation. When a cluster scoped Argo CD instance is used to manage resources across multiple tenant namespaces, it violates the principle of "least privilege" providing escalated privileges to all the tenants.

In this talk we will be looking at some of the best practices for handling privilege escalation in multi-tenant scenarios and how the recent feature of decoupling application syncs using a service account per tenant can be a real game changer in improving the security posture of Argo CD for mult-tenant scenarios.

Tuesday April 1, 2025 16:20 - 16:45 BST

Level 1 | Hall Entrance S10 | Room A

In order to manage a Kubernetes fleet of more than 400 clusters across 7 different types of cloud providers in over 22 regions, Adobe’s Kubernetes team has embraced GitOps at a massive scale. Leveraging Cluster API (CAPI), Amazon Controllers for Kubernetes (ACK), Argo CD, Argo Workflows, Prometheus and other Kubernetes controllers, fleet management was changed from a heavy burden to a tactical advantage. This talk covers what are top learnings of using GitOps in a way that is able to be used in production across a large organization, integrating CNCF projects have helped them scale the operations with a relatively small staff of engineers. You’ll see how through an exclusively open source toolchain Adobe was able to deploy thousands of changes a month, safely, securely, and with confidence.

Redefining the Multi-Cluster Story of Argo CD - Jann Fischer, Red Hat

Tuesday April 1, 2025 16:50 - 17:15 BST

Level 1 | Hall Entrance S10 | Room A

As we deploy, operate and manage an ever growing amount of clusters, and extend our cloud native applications to (far) edge locations, across regions, data centers, and environments, the current multi-cluster architecture of Argo CD is hitting its limits. To face this challenge we need to be ambitious: let’s revolutionize the multi-cluster story of Argo CD and enable it to scale out to the edge, all while keeping a central control plane.

In this talk, we will discover the new community-driven Argoproj-Labs project argocd-agent, that inverts the paradigm of the current Argo CD multi-cluster architecture; instead of having Argo CD connect to the clusters it manages, it lets those clusters connect to Argo CD through an agent.

Looking at some of the challenges and caveats that you face with the current multi-cluster architecture in Argo CD, we’ll explore how the agent model can improve scalability, reliability and security for large-scale Argo CD multi-cluster setups.
