	2022 Annual Report: SIG Node
Current initiatives
- 
What work did the SIG do this year that should be highlighted?
- Dockershim removal has big effect on community, 3rd party tools vendors and end users.
 - With CRI v1alpha2 removal we set the minimal compatible Containerd version. This is continuous trend as we require newer and newer dependencies.
 - Cgroups v2 GA opens up possibility for new features, but sets the minimal bar for dependencies again.
 - Cgroups v1 deprecation is on horizon.
 - No perma beta progress - keep removing and/or promoting old features. For example, DynamicKubeletConfig removed, various resource managers GA'd.
 - User namespaces for stateless pods entered alpha. It is a very old feature request.
 - Evented PLEG - working on minimization of kubelet overhead at bigger scale.
 - DRA was introduced which opens up more device integration scenarios.
 
 - 
What initiatives are you working on that aren't being tracked in KEPs?
- Keep working on CI stability and overall reliability of SIG Node components.
 - Refactoring E2E Node Tests to run against multiple cloud providers more easily.
 - Infra rehosting: new image registry and working on e2e tests on AWS.

Project health
- 
What areas and/or subprojects does your group need the most help with? Any areas with 2 or fewer OWNERs? (link to more details)
- Node Problem Detector is not very active and has small participation.
 - In general all areas are well covered with reviewers and approvers. However community would benefit to have clearer ownership of areas defined someplace. Ideas (https://github.com/kubernetes/community/issues/7234):
- Add more people to subdirectories as approvers
 - Split more clearly between approvers and reviewers
 
 
 - 
What metrics/community health stats does your group care about and/or measure?
- Active PRs and weekly changes of PRs at weekly SIG meetings.
 - Untriaged PRs, bugs - via CI group bug triage.
 - It will be great to have a PR full-cycle metrics to get insights into time to review and time to approve as well as number of iterations.
 
 - 
Does your CONTRIBUTING.md help new contributors engage with your group specifically by pointing to activities or programs that provide useful context or allow easy participation?
- No, current CONTRIBUTING.md is not adequately covers the getting started experience for the new contributors.
 - Ideas for improvements: https://github.com/kubernetes/community/issues/7223
 - Also we need clearer code organization documentation for Kubernetes. This is not specific to SIG Node, but due to size, SIG Node group would likely benefit the most from it.
 
 - 
If your group has special training, requirements for reviewers/approvers, or processes beyond the general contributor guide, does your CONTRIBUTING.md document those to help existing contributors grow throughout the contributor ladder?
- We published the SIG Node contributor ladder that details requirements for reviewers/approvers.
 
 - 
Does the group have contributors from multiple companies/affiliations?
- The group has contributors from multiple companies/affiliations.
 - 19 companies made 1+ contributions over the last year.
 
 - 
Are there ways end users/companies can contribute that they currently are not? If one of those ways is more full time support, what would they work on and why?
- Drive dockershim deprecation and report back issues. We still see the adoption not being very fast. It will be great to see more 3rd party tools vendors helping with migration.
 - We have another potential deprecation - cgroupv1 upcoming. It will likely be less impactful, but may need support.
 - Need more feedback from end users on various deprecations and a new features.
- Can we publish surveys and check on features usage from end users?
