Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack code, the SIG largely focused on bug fixes and updates to match K8s 1.13 development.

### SIG Scalability

* kubeadm now preserves previous manifests after upgrades ([#64337](https://github.com/kubernetes/kubernetes/pull/64337), [@liztio](https://github.com/liztio))
* Implement kubelet side online file system resizing ([#62460](https://github.com/kubernetes/kubernetes/pull/62460), [@mlmhl](https://github.com/mlmhl))



# v1.11.0-beta.1

[Documentation](https://docs.k8s.io)

* implement proposal 34058: hostPath volume type ([#46597](https://github.com/kubernetes/kubernetes/pull/46597), [@dixudx](https://github.com/dixudx))
* HostAlias is now supported for both non-HostNetwork Pods and HostNetwork Pods. ([#50646](https://github.com/kubernetes/kubernetes/pull/50646), [@rickypai](https://github.com/rickypai))

- Kube-proxy: added `--logging-format` flag to support structured logging. ([#117800](https://github.com/kubernetes/kubernetes/pull/117800), [@cyclinder](https://github.com/cyclinder))
- NodeVolumeLimits implement the `PreFilter` extension point for skipping the Filter phase if the Pod doesn't use volumes with limits. ([#115398](https://github.com/kubernetes/kubernetes/pull/115398), [@tangwz](https://github.com/tangwz)) [SIG Scheduling]

- Autoscaling/v2beta2 and custom_metrics/v1beta2 have been introduced, which implement metric selectors for Object and Pods metrics, as well as allowing AverageValue targets on Objects, similar to External metrics. ([#64097](https://github.com/kubernetes/kubernetes/pull/64097), [@damemi](https://github.com/damemi)) Courtesy of SIG...

- The kubelet and the default docker runtime now support running ephemeral containers in the Linux process namespace of a target container. Other container runtimes must implement support for this feature before it will be available for that runtime. ([#84731](https://github.com/kubernetes/kubernetes/pull/84731), [@verb](https://github.com/verb)) [SIG Node]

    * HostPortSyncer: operates only with one IP family, skipping portmap entries with different IP families
* Implement the documented API semantics of list-type and map-type atomic to reject non-atomic sub-types. ([#84722](https://github.com/kubernetes/kubernetes/pull/84722), [@sttts](https://github.com/sttts))

* kubeadm: added `--print-join-command` flag for `kubeadm token create`. ([#56185](https://github.com/kubernetes/kubernetes/pull/56185), [@mattmoyer](https://github.com/mattmoyer))
* Implement kubelet side file system resizing. Also implement GCE PD resizing ([#55815](https://github.com/kubernetes/kubernetes/pull/55815), [@gnufied](https://github.com/gnufied))

  - Add missing stable labels to template nodes
  
  ### HuaweiCloud
  - Add auto scaling group support
  - Implement node group by AS
  - Implement getting desired instance number of node group
  - Implement increasing node group size
  - Implement TemplateNodeInfo
  - Implement caching instances
  
  ### IONOS
  - Add support for IONOS
  
  ### Kubemark

- Adds feature gate `NodeLogQuery` which provides cluster administrators with a streaming view of logs using kubectl without them having to implement a client side reader or logging into the node.
