You can tune performance settings, configure security restrictions, customize the UI, and much more. The configuration options are exposed via many different interfaces such as ConfigMaps, CLI flags, and environment variables. It's often difficult to discover settings, understand the available options, and determine the defaults. This fractured configuration landscape also makes Argo CD difficult to maintain. It's difficult to understand which settings should be exposed where, how to document them, how they affect multi-tenancy, etc. Improving Argo CD's configuration experience is a huge challenge. But with careful planning, we can do it! Argo CD lead maintainer Michael Crenshaw will walk the audience through a proposal to allow configuring Argo CD via a new Custom Resource Definition. He'll walk through the various requirements: backwards compatibility, per-component configuration, migration path, etc.; and he'll describe the design decisions that come from each requirement. The audience will learn a lot about how Argo CD works and will get a glimpse into a bright future where configuring Argo is fun and easy! ### 14:15–14:40 · Introducing OCI Webhook Support in Argo CD: From Polling to Real-Time - Room: 3F l 313+314 - Speakers: Nitish Kumar, Surabhi Mishra - Track: Breakout Sessions - Labels: Any, Progressive Delivery - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1187445 As GitOps evolves, more teams are adopting OCI-based artifacts for Helm charts and Kubernetes manifests instead of traditional Git repositories. While Argo CD added support for OCI sources, one major gap remained: event-driven updates. Unlike Git repositories, OCI registries historically lacked first-class webhook integration, forcing teams to rely on polling or manual refreshes. For organizations using GHCR and DockerHub, this meant slower feedback loops and reduced automation in production environments. Argo CD is adding webhook support for OCI-compliant registries. In this session, we'll present the design and implementation of webhook support, including GHCR and upcoming Docker Hub integration. we'll also demonstrate how to configure registry webhooks, connect them to Argo CD, and trigger real-time reconciliation securely. By the end of this talk, you’ll understand not just how OCI webhooks work internally, but how to configure them correctly in production and what pitfalls to avoid. ### 14:50–14:55 · Sponsored Keynote | Octopus Deploy: CI/CD is now AI/CD - Room: 3F l 313+314 - Speakers: Mike Nguyen - Track: Keynote Sessions - Labels: Any - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1228365 AI has made developing and building new code easier—but has made deploying it safely and at scale harder. So, while producing new code in dev has increased exponentially, deploying it to production has not kept pace. And getting to production is the most important part. Enter CD PolicyOps. Learn how policy-driven CD gets you to production by understanding when simple tests will work and when manual approvals are needed—which services can tolerate short failures while others must never experience failure. See how AI, Argo CD, and GitOps, are the foundation of CD PolicyOps that gets you to production safely and at scale. ### 14:55–15:15 · Coffee Break - Room: 3F l 311+312 - Track: Breaks - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1228360 ### 15:15–15:40 · Argo CD Maintainer's Panel - Room: 3F l 313+314 - Speakers: Dan Garfield, Christian Hernandez, Nitish Kumar, Joanna Wyganowska - Track: Breakout Sessions - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1296597 ### 15:45–16:10 · When GitOps Becomes the Bottleneck: Scaling Argo CD for High-Churn Platforms - Room: 3F l 313+314 - Speakers: Sandeep Kanabar, Vanshika Jain - Track: Breakout Sessions - Labels: Any, Scalability - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1205876 GitOps is a force multiplier for stable delivery - until it becomes the bottleneck. On high-churn platforms - preview environments, tenant sandboxes, bursty onboarding, and session-scoped namespaces - a naive pattern of one Argo CD Application per short-lived unit can overload Git, back up reconciliation, and strain the Kubernetes API while teams wait for "Synced" to mean ready. This session shows where that breaking point appears and how to scale Argo CD without abandoning declarative operations. We trace the evolution from a per-environment model that collapsed under churn to a hybrid design where durable desired state stays in Git under Argo CD control, while high-frequency changes are batched, pooled, and driven through controlled automation. Attendees will learn practical patterns for structuring ApplicationSets and tenancy, reducing Git write pressure, and tuning reconciliation for bursty change, as well as trade-offs between pooling and isolation, and guidance on when to shard or split control planes. We’ll also show how event-driven scaling and service mesh fit around Argo to improve responsiveness and isolation. ### 16:15–16:25 · Lightning Talk: Migrating 1,300 Jenkins Jobs to Argo Workflows: Lessons from a Large-Scale Migration - Room: 3F l 313+314 - Speakers: Kenichi Takano - Track: Lightning Talks - Labels: Beginner, Software Delivery - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1206046 - Slides: https://sessionize.com/download/koxlac~RWBETUcCcJNphxEijQScKW.pdf~migrating-1300-jenkins-jobs-to-argo-workflows.pdf At StudySapuri (Recruit Co., Ltd.), our SRE team migrated 1,306 Jenkins jobs to Argo Workflows. Jenkins served us well, but we faced growing operational challenges: difficulty debugging failures across Jenkins and Kubernetes, painful upgrade processes, lack of audit trails, and no code-managed job definitions. In this lightning talk, I will share how we prepared for and executed this large-scale migration. We started with a Proof of Concept with one team, then developed a migration script that converts Jenkins job XML configurations into Argo Workflows manifests. We also established default Workflow settings including Datadog metrics reporting, log archiving to S3, and Slack notifications, which reduced the learning curve for adopters. After going to production, we encountered several issues: CronWorkflow history causing OOM in argo-server, pod deleted errors from Karpenter reclaiming nodes before Argo Workflows could read Pod exit status, and transient OCI runtime create failed errors. I will explain how we resolved each of these, including contributing a fix upstream to the Argo Workflows project. ### 16:30–16:40 · Lightning Talk: 10 Ways to Get Involved in Argo Project - Room: 3F l 313+314 - Speakers: Joanna Wyganowska - Track: Lightning Talks - Labels: Any, Progressive Delivery - Link: https://events.linuxfoundation.org/kubecon-cloudnativecon-japan/co-located-events/argocon/?id=1205895 - Slides: https://sessionize.com/download/ijhatmez~QKCVFNraxCeT9tsJ5EJJZr.pdf~2026-argocon-japan-10-ways-to-get-involved-in-the-argo-project-by-joanna-wyganowska.pdf Getting involved in Open Source Software (OSS) projects involves more than just coding. During this session, you will hear 10 ways you can get involved in Argo Project. From updating documentation and submitting feedback to evangelizing the project within your organization – everyone should be able to find a way to add value to Argo community.
