Standardizing CI/CD Observability With OpenTelemetry: Insights From the CI/CD Observability SIG - Dotan Horovits, OpenObservability Talks & Adriel Perkins, Liatrio

Wednesday April 2, 2025 12:00 - 12:30 BST

Level 3 | ICC Capital Suite 10-12

We all know that observability is a must-have for operating systems in production. But we often neglect our own backyard - our software release process. As a result, we also lack standardization, and each CI/CD tool invent its own way of reporting about pipeline runs, which causes fragmentation, lock-in and difficulty to leverage existing observability tools.

We've been talking about the need for a common "language" for reporting and observing CI/CD pipelines for years, and finally, we see the first "words" of this language entering the "dictionary" of observability - the OpenTelemetry open specification and semantic conventions. On this talk the OTel CI/CD SIG leads will share the need, and the work of the SIG.

Join us to learn about this new SIG, its role, the milestones achieved and roadmap ahead. The talk will also discuss the alignment with adjacent open source communities such as the CDF's Jenkins and CDEvents and the Eiffel community.

Simplifying Apache Kafka on Kubernetes With Strimzi - Lukáš Král & Gantigmaa Selenge, Red Hat

Wednesday April 2, 2025 15:15 - 15:45 BST

Level 3 | ICC Capital Suite 10-12

When it comes to data streaming platforms for modern event driven architectures, Apache Kafka has become the most popular choice. However managing Kafka clusters on Kubernetes brings its own set of challenges such as upgrades, topics management and scaling. This is where Strimzi shines, it’s a CNCF incubating project that makes running Kafka on Kubernetes seamless.

In this talk, we will briefly introduce Strimzi and its key features, exploring how it simplifies not just Day 1 but also Day 2 operations in a Kubernetes native way. We will then deep dive into Strimzi’s recent enhancements such as KRaft migration, auto rebalancing, and tiered storage.

From the Observability TAG: Designing a Common Query Language for Observability Data - Alolita Sharma, Apple & Pereira Braga, Google

Thursday April 3, 2025 11:00 - 11:30 BST

Level 3 | ICC Capital Suite 10-12

Unifying query languages is key in reducing toil for app developers and end users to query and analyze observability data. A common query language that can leverage all observability data such as metrics, traces, profiles, events, logs to facilitate correlation, support trend analytics and provide end-to-end observability for AI applications. The Observability TAG QLS workgroup published a common query language spec in 2024. The workgroup recommended a SQL-like language. This talk will explore the design principles and challenges of creating a generic query language. It will delve into the core concepts, syntax, and semantics of such a language, drawing inspiration from SQL while addressing the unique requirements of observability data. It will also explore the trade-offs between simplicity, expressiveness, and performance. This query language convergence for end-to-end analytics could enhance reliability and operational efficiency for SREs and your app developers. A win-win for all.

The Key To Security: Externalized Service Account Key Management - Mo Khan & Rita Zhang & Stanislav Láznička & Anish Ramasekar, Microsoft

Thursday April 3, 2025 11:45 - 12:15 BST

Level 3 | ICC Capital Suite 10-12

Service account signing keys are critical for JWT signing and authentication in Kubernetes, yet the current model - loading keys from disk during kube-apiserver startup - introduces challenges in key rotation and security. Restarting kube-apiserver for key rotation disrupts operations, while storing signing keys on disk exposes sensitive materials to potential exfiltration. This talk explores KEP 740 which is an enhancement to Kubernetes’ service account key management, enabling seamless integration with HSMs and cloud KMSes. By offloading signing to external systems, we eliminate the need for restarts during key rotations and significantly enhance security by removing signing materials from the filesystem. Join us to learn how these updates can strengthen security and auditability, and provide Kubernetes distributions with the flexibility to choose key management solutions that meet their needs.

Securing the Gateway: A Deep Dive Into Envoy Gateway's Advanced Security Policy - Huabing (Robin) Zhao, Tetrate

Thursday April 3, 2025 14:15 - 14:45 BST

Level 3 | ICC Capital Suite 10-12

Envoy Gateway, a growing project within the Envoy ecosystem, has steadily gained traction since its release, with v1.3 now available and adoption expanding across various production environments. It efficiently manages Envoy-based application gateways, fully complying with the Kubernetes Gateway API while extending its capabilities through custom resource definitions (CRDs) to address areas beyond the Gateway API's current scope. Envoy Gateway's Security Policy simplifies access to Envoy's robust security features, eliminating the need for users to navigate complex Envoy configurations. These features include CORS, JWT authentication, Basic Auth, OpenID Connect (OIDC), External Authentication (Ext Auth), and more. This session includes a demo showcasing OIDC authentication and authorization based on JWT claims, offering practical insights for enhancing application security—whether you're an experienced Envoy user or new to open source.
