⚡ Lightning Talk: `Kubectl Debug` Lacks an `IDE` Option. Let’s Fix That! - Mario Loriedo, Red Hat

Tuesday November 12, 2024 5:30pm - 5:35pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Don't get me wrong. `kubectl debug` is one of my favorite `kubectl` commands. But probably because I like it so much, I am convinced it deserves more love! This talk will present a `kubectl debug` extension that starts an IDE in an ephemeral container for debugging purposes. This extension uses the DevWorkspace operator, which is capable of running lightweight cloud development environments, including the IDE, in containers. If you like debugging by adding breakpoints in an IDE rather than inspecting your application's logs, you should attend this talk.

⚡ Lightning Talk: CloudEvents as APIs - Evan Anderson, Stacklok

Tuesday November 12, 2024 5:35pm - 5:40pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Most of us are familiar with tools like gRPC and OpenAPI for modelling synchronous calls between different applications or microservices. Sometimes, the right way to extend an application is through an asynchronous notification, or an event. CloudEvents is a CNCF project to standardize the format of asynchronous notifications, to make it easier for different projects and applications to communicate. CloudEvents is an envelope to make it easy to exchange asynchronous messages; in this talk, I'll highlight three useful patterns to leverage CloudEvents to connect applications, using examples from Stacklok's own experience.

⚡ Lightning Talk: Effortless, Sidecar-Less Mutual TLS and Rich Authorization Policies up and Running in 5 Minutes - Lin Sun, solo.io

Tuesday November 12, 2024 5:40pm - 5:45pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Do you need zero trust or mutual TLS (mTLS) among your application pods? You may be able to manage certificates within your applications, but how would you handle automatic periodic certificate rotation? The evolution of sidecar-less service mesh technology enables mTLS among application pods with just a simple namespace label. No sidecars or application pod restarts are required. This approach provides immediate benefits, including cryptographic identity for application pods, and ensures session-based data confidentiality and integrity in pod communications. In just 5 minutes, Lin will demonstrate live how developers and operators can effortlessly enforce mTLS and rich Layer 7 (L7) authorization policies without any sidecars!

⚡ Lightning Talk: Evaluating Scheduler Efficiency for AI/ML Jobs Using Custom Resource Metrics - Dmitry Shmulevich, NVIDIA

Tuesday November 12, 2024 5:45pm - 5:50pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Kubernetes deployments frequently utilize custom resources beyond just CPU and memory, such as GPUs, which are essential for AI/ML workloads. While the Metrics API offers insights into CPU and memory usage at both the pod and node levels, it does not provide similar information for custom resources. Although resource requests for custom resources are specified in the pod spec, there is no visibility into how efficiently these resources are utilized at the node and cluster levels. To address this gap, we developed a Prometheus Node Resource Exporter tailored to monitor custom resources. Our case study focuses on evaluating the efficiency of Kubernetes schedulers when handling a high volume of AI/ML jobs, using GPU occupancy on the nodes as the primary indicator. In this lightning talk, we will present a comparative analysis of several scheduling frameworks based on the metrics collected by our custom exporter.

⚡ Lightning Talk: Future-Proofing Kubernetes: Impact of Storage Version Migration and Meaning of Resource Version (RV) - Nilekh Chaudhari, Microsoft

Tuesday November 12, 2024 5:50pm - 5:55pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Kubernetes relies on API data being actively rewritten to support some maintenance activities related to at-rest storage. Two prominent examples are the versioned schema of stored resources (i.e., the preferred storage schema changing from v1 to v2 for a given resource) and encryption at rest (i.e., rewriting stale data based on a change in how the data should be encrypted). The simplest way to rewrite data is to issue no-op update requests via kubectl. This approach is problematic for any resource that can contain a large amount of data, such as Kubernetes secrets, and it is also impractical to perform without automation, as the number of resources that need migration is always growing. Storage Version Migration (SVM), which is now available as a built-in alpha API since Kubernetes v1.30, helps achieve this. However, the implementation of SVM has significant implications for the entire Kubernetes project and its ecosystem.

⚡ Lightning Talk: Is Everyone O-KEDA? “Exciting” Lessons Learned in Our Journey to Use KEDA Pod Autoscaling - Brian Davis, Red Canary

Tuesday November 12, 2024 5:55pm - 6:00pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

We thought that changing our Kubernetes pod autoscaler seemed like a really straightforward thing to do. With relative ease, we yanked out our old custom pod autoscaler and replaced it with KEDA. We were impressed with the flexibility and control we now had in our cluster, but then discovered a set of really hard lessons that no one had anticipated. In this lightning talk, I’ll hit the highlights of secondary issues we encountered due to such a seemingly simple change, such as Docker Hub rate limits, Kubernetes metrics server failures and their exciting impact on our cluster, AWS rate limits, and late night fights with Argo CD for control of pod maximums. Lastly, I’ll share my personal favorite topic: the “Night Club Theory” of autoscaling tuning. If you or someone you love is thinking of changing your autoscaler, I recommend spending 5 minutes with me to learn the things you should be aware of before you make the switch!

⚡ Lightning Talk: Minimizing Data Loss Within the OpenTelemetry (OTel) Collector - Alex Kats, Capital One

Tuesday November 12, 2024 6:05pm - 6:10pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

The OTel collector is meant to serve as a reliable and highly performant data pipeline. However, as a single component in a wider observability architecture, it is only as reliable as the downstream platforms/services it exports data to. The OTel collector has several built in mechanisms that aim to minimize the impact of unhealthy downstream exporters, including an out of the box sending queue with an additional configuration parameter for persistent queueing. There is a new component in the OTel contrib distribution, the Failover Connector. The Failover Connector allows for dynamic routing or “failover” of telemetry data based on downstream exporter health. This provides significant improvement to the data resiliency of the collector, as telemetry data can be continuously exported to a set of stable secondary locations, while the issues with the primary are resolved.

⚡ Lightning Talk: Running Kind Clusters with GPU Support Using Nvkind - Evan Lezar, NVIDIA

Tuesday November 12, 2024 6:10pm - 6:15pm MST

Hyatt Regency | Level 4 | Regency Ballroom BCD

Kind is a powerful tool for running local Kubernetes clusters using Docker. It is particularly useful for testing, development, and CI/CD workflows, offering features like multi-node cluster support, easy configuration, and cross-platform compatibility. However, providing access to GPUs in Kind is not a very straightforward process. There is no standard way to inject GPUs into a Kind worker node, and even with a series of "hacks" to make it possible, post-processing is still needed to isolate different sets of GPUs to different nodes. In this lightning talk, we introduce nvkind – a wrapper around Kind that encapsulates the steps necessary to make GPUs available to Kind worker nodes. Ideally, GPU support would have been added to Kind directly, but many challenges exist to make this possible. This talk discusses those challenges, how we've overcome them with nvkind, and the steps needed to eventually support GPUs directly within Kind itself.
