## Subprojects
|
||||
|
||||
### Kubefed
|
||||
Control Plane for newer Multicluster-specific APIs. Discussions are ongoing to focus future development on multi-cluster specific Kubernetes APIs rather than a reimplementation of single-cluster Kubernetes APIs.
|
||||
|
||||
| | |
|
||||
| -------------- |:-------|
|
||||
| Recommended for Production | Not yet. |
|
||||
| General Availability | Beta by 2018-Q4. GA TBD. |
|
||||
| Current Level of Activity | Once to twice weekly discussions as part of Kubefed working group (most active SIG-Multicluster members). |
|
||||

|
||||
|
||||
### Cluster Registry
|
||||
Common abstraction for a Registry of Clusters that can store per-Cluster metadata and supports Kubernetes label selection. The Cluster Registry can be deployed as a standalone or an aggregated API server and currently provides a Registry of Clusters without any actively reconciling Kubernetes controller. The API design is documented [here](https://git.k8s.io/design-proposals-archive/multicluster/cluster-registry/api-design.md) and is intended to serve as a basis to develop multicluster controllers.
|
||||
|
||||
| | |
|
||||
| -------------- |:-------|
|
||||
| Recommended for Production | Not yet. |
|
||||
| General Availability | Beta by 2018-Q1, GA by 2018-Q2 (see Project plan for details). |
|
||||
| Current Level of Activity | Alpha, active development for Beta and GA milestones. |

|
||||
### Kubemci (Kube Multi-cluster Ingress)
|
||||
Ability to program Global multicluster load balancers with two deliverables:
|
||||
* Standalone CLI tool without a centralized control plane. Allows ingress configurations that span multiple clusters. It needs to be invoked whenever there is a change in the number of clusters (healthchecking is still maintained in the background). Much of this work will be folded back into the next deliverable.
|
||||
* Kubernetes style multicluster API and self-healing controller with cluster registry
|
||||
|
||||
| | |
|
||||
| -------------- |:-------|
|
||||
| Recommended for Production | Not yet. |
|
||||
| General Availability | CLI: Beta by 2018-Q1, Controller: Alpha by 2018-Q1 |
|
||||
| Current Level of Activity? | CLI is alpha and team is looking for feedback. Active development is on to bring it to beta. |

|
||||
|
||||
### Federation v1 (a.k.a. Cluster Federation)
|
||||
Control Plane that coordinates configuration across multiple clusters by presenting a subset of the existing single-cluster Kubernetes APIs. Initially released as part of Kubernetes 1.3, Cluster Federation has implemented parts of the existing “single-cluster” Kubernetes API so that they may be used transparently in a multi-cluster fashion. As of Kubernetes 1.9, many of the non-Federated Kubernetes Workloads APIs have moved to GA (Deployments, ReplicaSets, Daemonset, StatefulSet). However, under Federation, these workloads have not reached the maturity of “GA” since they are re-implemented by different federated controllers. The SIG is currently re-thinking how to support Kubernetes APIs in a Federation fashion and this discussion is reflected under Kubefed.
|
||||
|
||||
| | |
|
||||
| -------------- |:-------|
|
||||
| Recommended for Production | No. Between Alpha and Beta levels of functionality depending on Kubernetes APIs used. |
|
||||
| General Availability | No target set date. |
|
||||
| Current Level of Activity | On Hold. See Kubefed. |
|
||||
| Owner(s) | [@shashidharatd](https://github.com/shashidharatd) |
|
||||
| Where to find it? | Out of main Kubernetes repository as of 1.9 and into its own [kubernetes/federation](https://github.com/kubernetes/federation) repository (kubefed is no longer distributed as part of Kubernetes client tools). Users have to build their own Federation Control Plane and kubefed client tool or wait on [issue #192](https://github.com/kubernetes/federation/issues/192) to be resolved. |

1. What work did the SIG do this year that should be highlighted?
|
||||
|
||||
<!--
|
||||
Some example items that might be worth highlighting:
|
||||
- Major KEP advancement
|
||||
- Important initiatives that aren't tracked via KEPs
|
||||
- Paying down significant tech debt
|
||||
- Governance and leadership changes
|
||||
-->
|
||||
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)?
