Navigating the Cgroup Transition: Bridging the Gap Between Kubernetes and User Expectations - Sohan Kunkerkar, Red Hat Inc

Thursday November 14, 2024 11:00am - 11:35am MST

Salt Palace | Level 1 | 155 BC

As Kubernetes and container technologies evolve, shifting from cgroup v1 to cgroup v2 has become a pivotal development. With cgroup v2 available in Kubernetes since v1.25, we're at a crossroads where many users and organizations must decide when and how to transition fully to this new system. Despite the benefits of cgroup v2, including better resource management and enhanced capabilities, users frequently encounter unexpected challenges signaling a gap in readiness and understanding. This talk will address the practical implications of moving to cgroup v2, discuss the coordinated efforts to deprecate cgroup v1, and propose actionable strategies to bridge the gap between the Kubernetes community, system administrators, and developers. By focusing on real-world experiences and providing clear guidance, this session aims to equip you with the knowledge and tools to navigate this significant change confidently.

Multi-Zone Clusters Inside and Out - Tom Dean, Buoyant

Thursday November 14, 2024 11:55am - 12:30pm MST

Salt Palace | Level 1 | 155 BC

Multi-zone clusters are a great tool for improving application reliability — and also a great way to spend a ton of cash. Why? What really happens when you set these things up? How do you use them effectively without bankrupting your whole organization? In this session, we'll dig into the nuts and bolts of what goes on under the hood of a multi-zone cluster, including what a zone is, what Kubernetes understands about zones, how zones affect routing, and why multi-zone clusters can drive costs up. We'll spend some time on Kubernetes' Topology Aware Routing, covering its advantages as well as its very real limitations. Finally, we'll dive into how you can influence Kubernetes' choices to take advantage of multi-zone clusters' reliability while containing costs. Join us for learning and live demos!

One Inventory to Rule Them All: Standardizing Multicluster Management - Corentin Debains, Google & Ryan Zhang, Microsoft

Thursday November 14, 2024 2:30pm - 3:05pm MST

Salt Palace | Level 1 | 155 BC

Most Kubernetes users run more than one cluster, and some run hundreds or more. Crossing cluster boundaries has always been a challenge, because most Kubernetes APIs, tools, and operators are cluster-centric. In fact, there’s a remarkable lack of standard tools and patterns for multi-cluster. Over time users have found ways to stitch clusters together but the community has been asking for standardization.To share multi-cluster tools, Kubernetes sig-multicluster has introduced the “ClusterProfile” API, a critical building block for multi-cluster capabilities. This API provides a canonical way for multicluster controllers and users to iterate over clusters, and to install or manage multi-cluster features. In this talk, we will look at some of the problems inherent to multi-clustering, explain the concepts introduced by this new API and look at implementations and consumers of it.We dive into real life examples of patterns and usage, with products such as Kueue, ArgoCD, and Argo workflow.

Orchestrating Quasi-Real Time Data Processing in the Computing Farm of the ATLAS Experiment at CERN - Giuseppe Avolio, CERN

Thursday November 14, 2024 3:25pm - 4:00pm MST

Salt Palace | Level 1 | 155 BC

What has Kubernetes got to do with a High Energy Physics experiment collecting one million physics events per second at a data rate of 5 TB/s? That is what we would like to show you! The ATLAS experiment at CERN filters one million complex collision signatures per second provided by the Large Hadron Collider in quasi real-time, using a mixture of custom electronics and a large computing farm (the Event Filter – EF – farm) consisting of up to 5000 commodity servers. In this talk, we will tell you how we are going to exploit Kubernetes to orchestrate the ATLAS EF computing farm. In particular, we will focus on the strategy and optimizations we put in place in order to start more than 25000 PODs over more than 2500 worker nodes in about 50 seconds. We will also show the impact of the Kubernetes Scheduler and Controller Manager QPS values on POD start and stop throughputs and we will report about how custom scheduler profiles allow us to schedule PODs at an average rate of about 500 Hz.

Per-Node Api-Server Proxy: Expand the Cluster's Scale and Stability - Weizhou Lan & Iceber Gu, DaoCloud

Thursday November 14, 2024 4:30pm - 5:05pm MST

Salt Palace | Level 1 | 155 BC

For lots of CNCF projects, kinds of daemonsets simultaneously synchronize datas from the Api-server from each node. Especially in large-scale clusters, it creates significant pressure on the Api-server, burdens the network, even affects the stability of the cluster. Some projects have implemented optimization to address this. For instance, Cilium aggregates endpoint information into the CRD CiliumEndpointSlice before distributing it to its daemonset. However, many projects have not yet adopted such data aggregation optimizations and Currently, there is still no project to help improve the communication between all components and the Api-server. ClusterPedia supports to launch per-node Api-server proxies to serve all local pods, and utilize eBPF to resolve the API server's clusterIP to the local proxy, which transparently implements API server access redirection on demand. In large-scale clusters, this can significantly improve the stability of all cluster's services.

Pod Power: Liberating Kubernetes Users from Container Resource Micromanagement - Dixita Narang, Google & Peter Hunt, Red Hat

Thursday November 14, 2024 5:25pm - 6:00pm MST

Salt Palace | Level 1 | 155 BC

In the dynamic world of Kubernetes, efficient resource management is crucial for optimizing performance and costs. Traditionally, managing resource requests and limits in Kubernetes has focused on individual containers within a pod. While this approach offers granular control, it can become cumbersome and error-prone, particularly for complex applications with multiple containers. Join us as we'll examine the challenges and scalability limitations posed by container resource micromanagement resource allocation. To address this issue, the pod-level feature specification is introduced. In this session, we'll delve into the transition towards pod-level resource specifications, providing an intuitive method for defining resource requests and limits at the pod level, in conjunction with the existing container-level settings. This innovative approach offers enhanced flexibility and optimized resource utilization for a variety of workloads, including those with init containers and sidecars.
