Evolving the YAML Family (without Breaking the World) - Ingy döt Net, YAML LLC
Wednesday October 7, 2026 11:20 - 12:00 CEST
YAML turned 25 this year.
It is essential to Kubernetes, Docker, Ansible, CI pipelines, and config files for everything in between.
That ubiquity is both a gift and a curse: every change risks breaking something, somewhere, silently.
So how do you grow a data language that a billion files depend on without risk of catastrophe?

Ingy döt Net helped invent YAML and he now maintains the YAML Specification and The YAML Family (libyaml, go-yaml, PyYAML, YAMLStar, YAMLScript etc).
In this talk he'll show how he plans to grow YAML by extension: a plugin system that can deeply affect YAML behavior in completely configurable ways.
Plugin APIs include schema association, tab indent, standard functions, comment support include i18n.
This is being delivered first to go-yaml with the rest of the Family to follow.
The work and its real world feedback will guide future changes to the specification.

How Git Clone Took Down Our CI for 20 Days - Yathartha Goenka, Mercari, Inc.
Wednesday October 7, 2026 13:30 - 14:10 CEST
One morning, CI across ~1,800 repos ground to a near-total halt. HTTP 401 from github.com, everywhere. Deterministic, not flaky. Valid tokens, healthy rate limits. GitHub support said "anti-abuse." We said "which abuse?"

Twenty days and 17,863,537 log records later, we'd gone deeper into git's open source plumbing than we ever intended: how git negotiates HTTP auth, what it leaks in user-agents, which config knobs actually matter under load, and how its defaults — sensible on a laptop — behave pathologically behind Kubernetes NAT at 50,000 CI runs a day.

This talk is a forensic walkthrough of git's HTTP transport, told through an outage: the red herrings, the tcpdumps, the fixes that didn't work, the fix that did. You'll leave knowing what git clone really does when you're not looking — and how to configure it so it never makes you look guilty.

Bring popcorn.

Kata at Scale: The Hidden Cost of Running VMs Behind Every Container - Kavitha Daula & Ann Wallace, Edera
Wednesday October 7, 2026 14:25 - 15:05 CEST
There is a big difference between getting Kata Containers running in a proof of concept and operating a large multi-tenant Kata environment for years.

This talk is a practical, vendor-neutral look at what becomes hard after the demo works. Once every pod carries a lightweight VM lifecycle behind it, platform teams are no longer operating only Kubernetes. They are also operating guest kernels, guest images, VMMs, hypervisor behavior, virtio devices, runtime and agent version skew, and a second debugging surface under the container platform.

We will walk through production issues that show up at scale: guest kernel CVEs and regressions, host/guest kernel drift, CNI and tap-device networking, virtio-fs and storage durability semantics, fragmented observability, boot storms, vCPU oversubscription, memory accounting drift, NUMA behavior, GPU passthrough, VFIO/IOMMU lifecycle, upgrade matrices, and incident ownership.

This is not a criticism of Kata. Kata solves a real open source isolation problem. The goal is to help operators understand the operational work required to run VM-isolated containers safely and sustainably in production.

Embracing Service-Oriented Connectivity Across OpenStack and Kubernetes - Mitsuhiro Tanino & Rei Shimizu, LY Corporation
Wednesday October 7, 2026 15:35 - 16:15 CEST
Modern infrastructure platforms increasingly combine OpenStack VMs, Kubernetes Pods, managed platforms, and external services, yet connectivity models often remain fragmented across runtime boundaries and tied to infrastructure-specific constructs such as IP-based ACLs.

This session presents how LY Corporation introduced a service-oriented connectivity model across OpenStack and Kubernetes environments. Rather than extending Kubernetes-native service mesh concepts to VM workloads, we introduced a runtime-independent service abstraction where connectivity and policy are defined consistently across VMs, Pods, PaaS instances, and external resources.

Under this model, services become the primary unit for service discovery, authentication and authorization, ACL management, and traffic control, independent of the underlying runtime or network topology. A sidecar proxy enforces service-to-service policy consistently across both OpenStack-managed VMs and Kubernetes workloads.

We cover the architectural design, OpenStack and Kubernetes integration for service registration and identity propagation, and lessons from migrating production workloads at scale.

Life Finds a Way , Sandboxed Agents, Observable Verdicts - Henrik Rexed, Dynatrace
Wednesday October 7, 2026 16:30 - 17:10 CEST
"Life, uh, finds a way." So do AI agents. Give one a tool, and a prompt-injected README will teach it to spawn a shell. CVE-2025-59528 (CVSS 10.0) and Google's Antigravity sandbox escape proved the same thing twice in 2025: the agent didn't break the sandbox , either the sandbox was missing, or the electric fence was in the wrong place.
This talk is a tour of Jurassic Park, rebuilt on Kubernetes. The paddock walls are containers. The electric fence is kubernetes-sigs/agent-sandbox, swapping gVisor for Kata Containers under the same CRD. The control room is OpenTelemetry where invoke_agent, execute_tool, and tool.policy_check spans turn every isolation verdict into queryable telemetry.
We will deploy OpenClaw ,an open-source AI agent gateway inside a Sandbox resource on Cluster API, watch the agent attempt three different escapes, and ship policy decisions as first-class spans. Help shape OpenTelemetry semconv #3583 before the park opens.

Teaching BIND9 New Tricks: A Rust Operator for Declarative DNS on Kubernetes - Erick Bourgeois, RBC Capital Markets
Wednesday October 7, 2026 17:25 - 18:05 CEST
Authoritative DNS is one of the last holdouts against declarative, GitOps-style management. BIND9 still serves a huge share of the world's zone data, but it's driven imperatively: hand-edited zone files, rndc reload, and brittle automation glued on top. bindy is an open-source Kubernetes operator, written in Rust on kube-rs, that closes the gap. It models zones and records as custom resources and continuously reconciles a running BIND9 against them, leaving no orphaned zone file behind.
This talk walks through the architecture of bindy and its sibling projects, bindcar, a sidecar that exposes RNDC operations over a typed API, and hornet, a Rust zone-file parser, then digs into the operator-engineering lessons that transfer to anyone writing controllers in Rust. We'll cover splitting selection from synchronization to avoid reconcile loops, using the reflector and store, modeling ownership and status conditions, and where Rust and kube-rs paid off versus Go's controller-runtime.
Attendees leave with a concrete, reusable pattern for wrapping any stateful, non-cloud-native daemon in a declarative Kubernetes API, and three open-source projects they can adopt, fork, or contribute to.

From Fragile To Self-Healing: Operationalizing Etcd at Scale - Shreyas Rao & Ishan Tyagi, SAP Labs
Thursday October 8, 2026 10:50 - 11:30 CEST
Running etcd across thousands of production Kubernetes clusters reveals critical failures: data corruption, quorum loss, member failures, and storage bloat, all capable of disrupting clusters. Managing these manually is complex, error-prone, and difficult to scale.

In this talk, we will be sharing lessons from 8+ years of operating production-grade etcd at scale with close to zero manual intervention and how we built etcd-backup-restore to reliably automate tasks like scheduled backups, corruption detection, quorum loss recovery, member replacement, and scheduled defragmentation, with zero recorded data loss across thousands of clusters.

Used in production by SAP Gardener, Akamai Cloud, StackIT, and Scaleway, etcd-backup-restore is now a Linux Foundation project under Linux Foundation EU via the NeoNephos Foundation, with an active maintainer community. We'll show what it takes to run etcd reliably at scale, and make it truly self-healing.

Own Your Stack: Sovereign Kubernetes From Bare Metal To Fleet - Sunnatillo Samadov, Ericsson & Bharath Nallapeta, Mirantis Inc.
Thursday October 8, 2026 11:40 - 12:20 CEST
For a decade, the default answer to "where does Kubernetes run" was someone else's cloud. But lately, regulated organizations, telcos, banks, and the public sector are pulling sensitive workloads back onto hardware they own and operate — for cost, performance, sovereignty, and increasingly to run AI and GPU workloads they control. The hard part is doing that without giving up the automation the cloud offers.

This talk covers the open-source stack for running your own bare metal, with each layer explained by the people who work on it. At the bottom, Metal3 turns physical servers into declarative Kubernetes resources and manages their lifecycle through the Kubernetes API. At the top, k0rdent manages fleets of those clusters with templates, policy, and drift detection. In the middle sits Cluster API, the standard both layers build on.

We'll walk through the layers working as one — from a rack of bare metal to provisioned clusters to a managed fleet, on hardware we run ourselves. Attendees get a reference architecture, practical guardrails, and clear criteria for when this fits. We'll be honest about the trade-offs: slower provisioning and elasticity bounded by the servers you have.

Make YAML Dumb Again: The Config as Data Approach - Jaisheesh Venkat Goud, ABV-Indian Institute of Information Technology and Management Gwalior & Liam Fallon, Ericsson Software Technology
Thursday October 8, 2026 13:50 - 15:20 CEST
Building on my Google Summer of Code experience, this tutorial addresses one of the major challenges in open source software systems – at scale, file management results in overly complicated templates and bad composability. People put logic into YAML files resulting in non-debuggable pipelines while local modifications are wiped away by upstream updates.
This tutorial delves into the idea of Configuration as Data with the help of kpt tooling allowing for logic separation from configuration files. The idea is to keep YAML "dumb" and pure data, which makes it fully predictable and WYSIWYG.
You’ll get to use the example of the OpenTelemetry Demo - a complex e-commerce microservices application – by packing it in independent and dependent subpackages.
Using KRM functions and custom Starlark scripts you'll:
• switch from a shop selling astronomical equipment to a website offering flowers
• localize languages, currencies, taxes
• manage different deployments sizes (small/medium/large).
As the last point you will use three way merging to allow applying upstream package updates while keeping all local changes safe.

KubePACS: From Systems Research To Open Source Spot Instance Provisioning on Kubernetes - Kyungyong Lee, Hanyang University
Thursday October 8, 2026 15:50 - 16:30 CEST
Spot instances reduce cloud bills by up to 90%, but choosing which to use is a multi-dimensional puzzle where price, performance, interruption risk, and instance heterogeneity all interact. Kubernetes provisioners like Karpenter optimize a narrow slice of this problem, tightly coupled to a single cloud vendor, AWS.

KubePACS is an open source project that separates the decision from the execution. A vendor-neutral optimizer computes the best mix of instance types for a workload's cost-performance-availability profile, then translates that into native configuration for the user's provisioner

The talk goes deep into the system: the ILP-based selector for cost-performance-availability trade-offs, the GSS-driven optimizer that tunes them automatically, multi-node spot placement awareness for robust capacity across cloud providers, and clean integration with upstream Karpenter.

Attendees see measured gains over baseline configurations and take away an architecture pattern for performance-aware spot instance provisioning. We close with our intent to grow KubePACS as an open source community effort and welcome contributors to shape what comes next.

Stateless by Design: Lessons From Building Infrastructure-as-Code Without Local State - Prashansa Kulshrestha, Kong Inc
Thursday October 8, 2026 16:40 - 17:20 CEST
Most IaC tools, Terraform chief among them, keep a local copy of state to plan changes, detect drift, and resolve references. That state file is also a known source of pain: it can go stale, get corrupted, and become a coordination bottleneck.

What happens when an IaC system deliberately keeps no local state? Instead of a stored snapshot, every operation reconciles desired configuration against live state at apply time. That single choice shapes everything else, and not all of it is smooth sailing.

Drawing on her experience building widely adopted open-source declarative CLIs, Prashansa unpacks the lessons she learned. The talk covers the tradeoffs statelessness forces: full-state sync versus additive configuration and when each fits, resolving references without a stored dependency graph, schema-aware diffing, and transparent reconciliation so users see what a tool does. It also covers production challenges: compatibility across platform versions, evolving schemas, and keeping behaviour predictable as systems grow.
Attendees will leave understanding why most IaC tools rely on state, what gets simpler and harder without it, and how to weigh these tradeoffs in their own systems.

Lightning Talk: Declarative Systems Still Have Hidden State - Kim Schaefer, Game Plan Tech
Friday October 9, 2026 11:05 - 11:15 CEST
Declarative infrastructure promises reproducibility: desired state is defined, controllers reconcile drift, and redeployments should behave predictably.

Except they often don’t.

This talk explores the hidden operational state declarative systems quietly depend on: webhook certificates cached in cluster resources, infrastructure dependencies that survive deletion, controller ordering assumptions, persistent node state, and lifecycle coupling reconciliation engines cannot see.

These problems become especially visible when infrastructure spans multiple systems or workloads take minutes rather than seconds to initialize.

Using real operational examples from Kubernetes and GitOps environments, this lightning talk examines why “delete and redeploy” frequently fails to produce clean state and why many reliability problems are actually hidden state-management problems.

The core lesson: declarative systems still depend on operational history, even when the infrastructure appears fully declarative.

Lightning Talk: One Line of YAML Leaks Your Secrets: The Pwn-Request Pattern - Arpit Jain, Self Employed
Friday October 9, 2026 11:15 - 11:25 CEST
A pull_request_target trigger plus ref: ${{ github.event.pull_request.head.sha }} in a checkout step. That combination lets any external contributor run arbitrary code with your repository's secrets and write token. This is the "pwn request" pattern, and it's in production workflows across some of the most popular open-source projects on GitHub.

I'll use a real finding (a CRITICAL-severity pwn request I discovered and privately disclosed in an Apache project) to explain how the attack works: what pull_request_target does differently from pull_request, why adding permissions: read-all doesn't protect you, and why the attacker needs nothing beyond opening a pull request.

Then I'll show the three mitigations that work: splitting into unprivileged build and privileged post-processing steps, using persist-credentials: false, and gating on the head repo matching the base.

Lightning Talk: Beyond Immutable Machines: Introducing Cluster API In-Place Updates - Lennart Jern, Ericsson Software Technology
Friday October 9, 2026 11:25 - 11:35 CEST
Cluster API (CAPI) is by now a relatively mature project with many adopters using it in production already for years. Despite this, or perhaps rather thanks to it, CAPI keeps evolving, growing and adding new features. In this session, I'll present one of the most recent features: in-place updates.

In-place updates marks an important change to a fundamental assumption in CAPI. Traditionally, the Machines were considered mostly immutable. Any change required a replacement where new Machines were created and old Machines deleted. This method of operation has served CAPI well, and continues to do so, but it is not without pain points. With in-place updates, it is now finally possible to avoid replacement. This opens the door for unique use-cases and solutions, such as Talos, where each node's lifecycle can be managed through a built-in controller in the node itself.

Come learn about this new feature in CAPI, and how to make use of it!

Your Agent Did What? Forensic Observability for Systems That Don’t Leave Obvious Footprints - Adriana Villela, Dynatrace & Kasper Borg Nissen, Dash0
Friday October 9, 2026 11:55 - 12:35 CEST
The GenAI observability space is fragmented right now. OpenInference, OpenLLMetry, framework-specific conventions are all solving the same problems with incompatible attribute names. That made sense when OTel’s GenAI support was thin. It makes less sense today.

OTel is where this converges. Getting there from where most teams actually are isn’t obvious. Kasper and Adriana cover the current landscape, how the genainormalizer processor bridges the gap at the collector layer, and what a realistic path to OTel-native GenAI observability looks like.

Then the harder question: your agent just deleted a database. What does your telemetry actually tell you? Non-deterministic systems don’t leave obvious footprints, and most teams discover that at the worst possible time.

Container Metrics on Diverse Hardware: Driving Observability, Efficiency, and Real-Time Autoscaling - Sambhav Jain & Digvijay Singh Shekhawat, Uber
Friday October 9, 2026 14:00 - 14:40 CEST
Uber runs about 4 million containers on over 150,000 hosts. Our fleet includes a mix of cgroupv1 and v2 hosts, multiple cloud providers, and multiple Linux kernel versions. Tracking container performance at this massive scale is a difficult engineering challenge, including the cost of storing them. We currently process 60 million data points every second to keep everything running smoothly.

We run Cadvisor and open-source Nvidia and AMD GPU metrics exporters to reliably and affordably collect and store these metrics. This infrastructure is vital for our real-time autoscaling, which ensures our services stay online. We also use these metrics to track memory usage and keep costs low for our AI workloads. Despite maintaining all the critical use cases, we have saved around $ 4 million compared to last year by changing how we collect and store data.

We will share how we use these metrics to detect and prevent system failures before they affect users. Attendees will learn practical patterns for operating container metrics at scale. We will also discuss the hard lessons we learned while building a reliable metrics system for a complex global fleet.

Friday October 9, 2026 15:40 - 16:20 CEST
The telco industry has been on a cloudification journey for over a decade. In the context of Radio Access Networks (RAN), this deep transformation is primarily driven by Open RAN initiatives. This talk illustrates how RAN is gradually embrassing cloud native benefits. Key synergies between Sylva and Duranta open-source projects are driving this transformation:
- Sylva provides a telco-grade cloud stack, enabling scalable and reliable cloud infrastructure.
- The Duranta project focuses on developing RAN network functions using cloud-native design patterns to promote innovation and interoperability.

A live demo will highlight the role of Open RAN interfaces in Duranta. It will showcase a FluxCD-based GitOps deployment of Duranta’s Open RAN Distributed Unit (O-DU), Centralized Unit Control Plane (O-CU-CP), and Centralized Unit User Plane (O-CU-UP) network functions on a Telco Cloud. The deployment will follow the Sylva GitOps approach. Sylva will orchestrate multiple Telco Clouds to showcase central, regional, and far-edge deployment scenarios across two labs located approximately 1,000 km apart.

Scatter-Gather in Sharded Worlds: Implementing Resilient Cluster Scans Without Starving Shards - Sakshi Nasha, Cohesity & Primanshu Choudhary, GetYourGuide
Friday October 9, 2026 16:30 - 17:10 CEST
Have you ever run a global pattern search or database scan across a large cluster, only to watch your application latency skyrocket and healthy nodes suddenly drop offline?

When applications outgrow a single instance, global data scanning becomes a major distributed systems bottleneck. High-level frameworks try to mask this complexity with simple abstractions, forcing the client driver to execute a "scatter-gather" pattern: fanning out parallel cursor queries to thousands of logical shards and merging the reactive results on the fly. If designed naively, a single slow shard or an unindexed query can exhaust the client's connection pool, leak memory, and starve production read/write traffic.

In this practical, code-focused session, we will open up the engine hood of high-performance drivers using live examples from the Valkey-Glide ecosystem. We will show you how to safely bridge high-level data abstractions down to sharded sockets without risking cascading timeouts.
Come Join us, to build Resilient Cluster Scans Without Starving Shards!
