What areas and/or subprojects does your group need the most help with? Any areas with 2 or fewer OWNERs? (link to more details) - Growing additional reviewers and approvers, also see no. 4 below. 2. What metrics/community health stats does your group care about and/or measure? - Open untriaged issues and PRs 3. 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? - It's up-to-date. 4. 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’re working with SIG-CLI on starting a monthly review club, details to be announced soon. 5. Does the group have contributors from multiple companies/affiliations? - [11 companies](https://k8s.devstats.cncf.io/d/8/company-statistics-by-repository-group?orgId=1&var-period=y&var-metric=contributions&var-repogroup_name=SIG%20Apps&var-repo_name=kubernetes%2Fkubernetes&var-companies=All&from=1609455600000&to=1639350000000) contributed code in 2021. 6. 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? - Increase the test coverage for all controllers. ## Membership - Primary slack channel member count: 2900 - Primary mailing list member count: 674 - Primary meeting attendee count (estimated, if needed): 10 - Primary meeting participant count (estimated, if needed): 6 - Unique reviewers for SIG-owned packages: 23 - Unique approvers for SIG-owned packages: 31 Include any other ways you measure group membership ## Subprojects New in 2021: - None Retired in 2021: - None Continuing: - [application](https://git.k8s.io/community/sig-apps#application) - [examples](https://git.k8s.io/community/sig-apps#examples) - [execution-hook](https://git.k8s.io/community/sig-apps#execution-hook) - [kompose](https://git.k8s.io/community/sig-apps#kompose) ## Working groups New in 2021: - None Retired in 2021: - None Continuing: - [Data Protection](https://git.k8s.io/community/wg-data-protection/) ([2021 report](https://github.com/kubernetes/community/blob/master/wg-data-protection/annual-report-2021.md)) ## Operational Operational tasks in [sig-governance.md]: - [x] [README.md] reviewed for accuracy and updated if needed - [x] [CONTRIBUTING.md] reviewed for accuracy and updated if needed (or created if missing and your contributor steps and experience are different or more in-depth than the documentation listed in the general [contributor guide] and [devel] folder.) - [x] Subprojects list and linked OWNERS files in [sigs.yaml] reviewed for accuracy and updated if needed - [x] SIG leaders (chairs, tech leads, and subproject owners) in [sigs.yaml] are accurate and active, and updated if needed - [x] Meeting notes and recordings for 2021 are linked from [README.md] and updated/uploaded if needed - [x] Did you have community-wide updates in 2021 (e.g. community meetings, kubecon, or kubernetes-dev@ emails)?
