Kubernetes Contributor Summit North America 2024: Full Schedule

CGroup V1 is being phased out in many distributions and container runtime communities. Dropping support for cgroup v1 is a challenging task due to the long tail of operating systems. In this talk, we will discuss methods for deprecating cgroup v1 and include ways to phase cgroup v1 out. We will discuss ways to formalize the deprecation of cgroup v1 for distributions. We will also give an overview of what cgroup v2 benefits us and some features that the Kubernetes community should be excited about.

Introducing "New Contributor Orientation!"

Monday November 11, 2024 10:45am - 11:10am MST

Room 254, Level 2

SIG-ContribEx recently started a new initiative to help new contributors get involved with the community. The monthly New Contributor Orientation meetings are designed to orient new contributors in the community by providing a basic overview of what Kubernetes does as a technology, how the community is structured, and how they might fit within it. The presentation is followed by a Q&A period where prospective new contributors can get guidance that matters to them. In this session, we'll provide an overview of the content provided at these sessions, share our learnings from running them for 2 months so far, and open it up to your feedback. This initiative is meant to help all SIGs, and we value your input!

Contributing to Kubernetes: why is this so damn hard?!

Monday November 11, 2024 11:20am - 11:45am MST

Room 254, Level 2

Everyone here thinks Kubernetes is great… so shouldn’t it be easier to improve it?

Over the last ten years, Kubernetes has become a force to be reckoned with in infrastructure management, using its powerful container orchestration features to solve problems around the world. Of course, no good deed goes unpunished: this rapid adoption and meteoric growth has brought with it a dramatic rise in the difficulty of effecting change within Kubernetes itself, leaving many in the community around this massively successful, phenomenally useful platform with no sense of how they can fix the issues that a decade of experience is bringing to light.

Fortunately, while we believe that this it's probably inevitable for any project growing so big so fast to land here, we do think that there's a way out! Join us as we dig into the issues with trying to get things done in Kubernetes, with particular emphasis on the KEP process (and what drives projects to go around it), as well as on CRD APIs (and their challenges with versioning and the user experience). More importantly, though, join us to dig into how we can all work together to fix these issues -- even while the platform shifts underneath us.

wg-lts: proposal to increase release lifetime with regards to CVEs

Monday November 11, 2024 11:20am - 11:45am MST

Room 255 d, Level 2

The security releases proposal [1] attempts to take a slightly different approach to LTS than what is traditionally discussed. Instead of trying to mark any particular Kubernetes release as LTS, it proposes that we increase the supported lifetime of all Kubernetes releases, but with only security fixes being backported after the initial 14 months. Such a change has an impact on a broad set of community members, so lets take this opportunity to discuss things in person.

A Deep Dive into the Kubernetes Streaming API's

Monday November 11, 2024 11:55am - 12:20pm MST

Room 254, Level 2

Most users know a cluster exposes an HTTP/REST API; but interactively communicating with a container requires more performance than the typical HTTP request-response mechanism can provide. Which is why Kubernetes clusters also expose bidirectional streaming interfaces. This presentation dives deeply into the mechanics of the Kubernetes streaming interfaces. We will follow the streamed data as it traverses numerous components of the cluster from a client such as kubectl to the API Server, through a kubelet on a Node, through the Container Runtime Interface (CRI), all the way to the container runtime itself. We will finish by outlining the newest efforts to modernize the Kubernetes streaming protocol from the current aging SPDY to WebSockets (SIG API Machinery - KEP 4006).

In-person Device Management Working Group Meeting

Monday November 11, 2024 11:55am - 12:50pm MST

Room 255 d, Level 2

The device management working group is a newly formed working group with an active contributor base. It's first goal is to get "Dynamic Resource Allocation (DRA)" promoted to beta (and eventually GA). Unfortunately, many of the regular attendees to the working group meetings have never met in person. This session is an opportunity for all members to finally meet face-to-face. The co-chairs of the working group will present a few slides and then open the floor to general discussions around the technical topics pertinent to the working group.

Official Kubernetes CRDs: Where to from here?

Monday November 11, 2024 11:55am - 12:50pm MST

Room 255 a, Level 2

With the success of Gateway API, other projects, like AdminNetworkPolicy, have also started development using out-of-tree CRDs to enable rapid iteration.

However, this has led us back to the problem of ensuring that the CRDs are installed, at the correct version, with possibly multiple implemenations of an API installed in the cluster that may need multiple versions.

For Gateway API, we've definitely had user and contributor requests to find some way to have the CRDs more readily available in most clusters.

This session is to discuss all of these things and try and get some momentum behind _some_ action in this area, whether that is something like the proposed documentation or more.

Multi-networking: Challenges, progress and what's next

Monday November 11, 2024 2:05pm - 2:30pm MST

Room 255 a, Level 2

This session is to provide an overview of the current state of multi networking within Kubernetes, highlighting the work done by the Multi-Network WG which sits at an intersection with numerous ongoing efforts and groups – the Device Management WG and structured parameters for DRA, container runtimes, CNI (and the future of CNI) and naturally – SIG-Network. There are a number of challenges surrounding a decision to work out of core, paths forward for integrated network functionality (like services), and legacy implementations.

We'll address some of the legacies of what previous technologies and paradigms folks have been using, such as NetworkAttachmentDefinitions, and Network Service Mesh – and talk about the trade-offs these projects had working out of core, and what we can do to reduce those trade offs – notably, with service-like functionality.

This includes discussing the ongoing development of the Multi-Network KEP Phase I, some of the POCs around combining technologies, and the move to using CRDs. Most importantly, the session aims to gather feedback and foster discussions on the next steps – and especially to get feedback from and alignment with other critical groups.

Traditionally, E2E testing has been based on Ginkgo, whereas unit and integration testing are based on `go test`. Because of the different APIs, different helper packages have been developed for both although the often do the same thing (create objects

ktesting is an abstraction of common functionality (reporting failures, logging, cleanup, timeouts). We could use it to unify the test helper code. But should we?

This session provides a comparison of Ginkgo vs. `go test` and how ktesting hides the differences. It explains some API choices made for ktesting.

Brainstorming the Promise of PSI

Monday November 11, 2024 2:40pm - 3:05pm MST

Room 255 a, Level 2

PSI (pressure stall information) are metrics the kernel optionally emits that gives finer grained timeseries information on resources uses on the node. Other projects like Facebook's oomd have used these metrics to preempt workloads from being OOM killed and instead give them a more graceful lifecycle. runc 1.2.0 will eventually expose these metrics, and KEP 4205 will add them to kubernetes, but this is just the first step. Join Peter and Dixita in a roundtable discussion on various ways PSI metrics can be utilized in kubernetes. Improved OOM killing? Better informed eviction? Variable swap allocations? The sky is the limit!

Metaresources & Policy Attachment

Monday November 11, 2024 3:30pm - 4:30pm MST

Room 255 d, Level 2

Gateway API (SIG-NETWORK) introduced Policies as a declarative mechanism to enhance Kubernetes objects like Services and network extensions such as Gateways and HTTPRoutes. These Policies–more generally referred to as Metaresources–are the central piece of a pattern known as Policy Attachment, which is heading to new levels of maturity, evolving from initially an inventive way to expand solidified stable APIs, now into a new standard in the making across several networking-related implementations for contextual API extensions. This session will delve into the concept and evolution of Metaresources & Policy Attachment, exploring its goals, current state, and future potential.
