Oh no, another weekend production upgrade coming up?
In the world of platform engineering, we often come across “weekend upgrade” scenarios. Such upgrades usually involve the presence of various team members during off-business hours for testing pre and post upgrades. It often requires downtime in business-critical applications. In this talk, the speakers will go through the traditional sidecar-based service mesh upgrade experience and the challenges associated with it. Then compare the same with the sidecar-less Ambient mesh upgrade experience. Discuss the best practices, and share guidance on how to set up a near-zero downtime upgrade process.
From Pods to Entities: Reimagining Kubernetes for a World of Intelligent Entites
This presentation explores a paradigm shift in Kubernetes' role, moving beyond container orchestration to the management of intelligent entities. As robots evolve into sophisticated, AI-driven collaborators, traditional management approaches falter. This talk introduces a novel framework that reimagines Kubernetes pods as persistent agents representing individual robotic entities.
The session delves into the technical details of this approach: utilizing Custom Resource Definitions (CRDs) to model entity types, manage individual entities, and control their interactions within groups. It highlights the use of standardized endpoints for interoperability, ensuring seamless communication between diverse robotic platforms. The solution's emphasis on decentralization, security, and stateful management through Kubernetes' core strengths is underscored.
Getting Started with K8sGPT: Making Kubernetes Troubleshooting Easier for SRE Teams
Want to master Kubernetes troubleshooting? In this hands-on session, learn how to harness K8sGPT's AI capabilities to solve real Kubernetes problems. SRE teams spend 25-30% of their time debugging – discover how K8sGPT can dramatically reduce this while making you a more efficient operator.
Step by step, we'll walk through setting up K8sGPT, understanding its core features, and applying it to common scenarios. You'll learn practical troubleshooting patterns, from basic pod failures to complex networking issues. See how K8sGPT interprets problems and provides actionable solutions in plain language.

Beyond Security: Leveraging OPA for FinOps in Kubernetes
The Open Policy Agent (OPA) is widely known for enforcing security policies, but its capabilities extend far beyond compliance. This session explores how OPA can be harnessed for FinOps practices in Kubernetes. Learn how to create policies to enforce cost-efficient resource requests, limit the use of high-cost instance types, and ensure workloads adhere to budget constraints. Discover how to integrate OPA with tools like Gatekeeper and OpenCost to provide real-time cost visibility and actionable insights. Through practical examples, attendees will gain the skills to use OPA for both security and cost optimization in Kubernetes environments.
