2024 Annual Report: SIG Multicluster

Current initiatives and Project Health

1. What work did the SIG do this year that should be highlighted?

Stephen Kitt (@skitt) replaced Paul Morie (@pmorie) as SIG co-chair.

Significant progress was made on graduating KEP 1645 to beta; the only remaining item is collapsing the ServiceImport spec and status fields to root, https://github.com/kubernetes-sigs/mcs-api/pull/52 or https://github.com/kubernetes-sigs/mcs-api/pull/85.

A conformance suite for KEP 1645 has been implemented in https://github.com/kubernetes-sigs/mcs-api/tree/master/conformance

CI for the mcs-api repository was revamped, with presubmit jobs added to test-infra: https://github.com/kubernetes/test-infra/pull/33393

A lot of discussion happened around ClusterProfile credentials storage.

2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?

No.

3. Did you have community-wide updates in 2024 (e.g. KubeCon talks)?
