Conference: KubeCon + CloudNativeCon North America 2022

These are exciting times for Kubernetes SIG Node. Many deprecation and graduations happened and many new initiatives are starting now. Come to our maintainers track session to learn about the recent releases of Kubernetes, full of exciting improvements and get a glance into the SIG Node roadmap. SIG Node owns components that control interactions between pods and host resources, including the Kubelet, Container Runtime Interface (CRI), and Node API. SIG Node is responsible for the Pod’s lifecycle from allocation to teardown, to liveness checks and shared resource management. We work with the various container runtimes, kernels, networking, storage, and more; anything a pod touches is SIG Node’s responsibility! We will talk more about cgroup v2 adoption and exciting opportunities it brings, how we invest in small quality of life improvements and working on new exciting big features. Join this session to learn more about our SIG, and how you might get involved to make Node even better!

The presentation discusses the future of Cloud Native applications and their impact on infrastructure. It explores the concept of emergent systems and how it applies to the community. The speaker predicts that applications will eventually be able to deploy anywhere in the world based on their requirements.
- Cloud Native applications are replacing sysadmins as the primary focus for runtimes and tooling
- New runtime environments are being built on lessons learned from the community to increase developers' capabilities
- Emergent systems have unique behaviors that arise as part of the system, and there is no global control or observability
- Applications will eventually be able to deploy anywhere in the world based on their requirements
- Human processes are impacted by changes in APIs and standards
- The community needs to be thoughtful and careful in taking Cloud Native to the next level

The presentation discusses the efforts made by GetPad to speed up image pull times by implementing caching mechanisms using IPFS and a registry facade.
- GetPad tried pre-pooling images, pre-baking them into VM images, and relying on Kubernetes mechanisms, but these methods were not effective in reducing image pull times.
- The solution was to use a registry facade that dynamically assembles the manifest and points to an instance of IPFS for caching mechanisms.
- Nerd control IPFS registry was explored but was not the solution to the problem.
- IPFS is a peer-to-peer based distributed file system that can be used for caching mechanisms.

Choosing the right container runtime engine is crucial for different use cases. Docker is a good option for developers, but there are other options like Podman, GVizor, Kata, and Firecracker for more secure and isolated environments. Kubernetes can work with different OCI compliant runtimes.
- Traditional deployment of applications can be unreliable
- Virtualization creates isolated environments but can be limiting
- Containers allow for deploying applications with all dependencies while still having access to host resources
- Docker is a good option for developers but has restrictions
- Podman can be a drop-in replacement for Docker and is more secure
- GVizor, Kata, and Firecracker are options for more isolated environments
- Kubernetes can work with different OCI compliant runtimes

Unikraft is an open-source library operating system that enables the construction of ultra-lightweight VMs quickly, easily and without time-consuming developer effort. These VM images are tailored to the application itself and have high-performance, low resource usage and a small attack surface. The talk compares Unikraft with existing runtimes for the cloud and demonstrates how it can be used with Kubernetes today.
- Existing runtimes for the cloud rely on traditional kernel stacks and hypervisors, which negatively impact security and performance.
- Unikraft is an open-source library operating system that enables the construction of ultra-lightweight VMs quickly, easily and without time-consuming developer effort.
- Unikraft VM images are tailored to the application itself and have high-performance, low resource usage and a small attack surface.
- Unikraft can be used with Kubernetes today.
- Unikraft supports major cloud vendors such as AWS and GCP.

These are exciting times for Kubernetes SIG Node. Come to our maintainers track session to learn about the just released version 1.24 of Kubernetes, full of exciting improvements and get a glance into the SIG Node roadmap. SIG Node owns components that control interactions between pods and host resources, including the Kubelet, Container Runtime Interface (CRI), and Node API. SIG Node is responsible for the Pod’s lifecycle from allocation to teardown, to liveness checks and shared resource management. We work with the various container runtimes, kernels, networking, storage, and more; anything a pod touches is SIG Node’s responsibility! We will discuss how Container Runtime logic was streamlined and simplified with dockershim removal, progress on cgroup v2 support, as well as many other improvements. Join this session to learn more about our SIG, and how you might get involved to make Node even better!Click here to view captioning/translation in the MeetingPlay platform!
