Pushing Multi-Arch Images The Right Way

Taylor Silva - Maintainer of Concourse CI

I had a CI job that built a multi-arch image using BuildKit. When looking up the image on Docker Hub it wasn't being recognized as a multi-arch image. To resolve this issue I had to dig into how BuildKit exports OCI images and figure out how to update my CI tooling to push the images correctly.

This talk explores the OCI Image specification and looks at how other tools like ORAS push OCI images.

Event Processing at Scale with a Kubernetes-Native Platform

Keran Yang - Staff Software Engineer at Intuit

Event-driven applications are essential for building scalable, responsive systems that handle real-time data streams efficiently. At Intuit, these architectures empower teams to react instantly to critical business events—unlocking real-time insights and driving automation across services.

In this session, we’ll explore the power of event-driven architecture using Numaflow, an open-source, Kubernetes-native platform developed at Intuit. You’ll get hands-on experience building serverless event-driven applications using Numaflow in the programming language of your choice. We’ll cover its core features, including autoscaling, seamless integration with event streams like Apache Kafka, and more.

Sandboxing Pods with runc

Jamon Camisso - Engineering Manager at Chainguard

Ever wanted to run k3s inside K8s (safely and reliably)? What about systemd, or podman or Docker? In this session, we'll explore how alternative runc implementations can be used to provide more secure and more capable pods than the default.

Defining SLOs and SLIs for ArgoCD: A Metrics-Driven Approach to Observability

Serhiy Martynenko - Senior Software Engineer at The New York Times

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).

• 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.
