### SIG-ibmcloud

As a newly created SIG, the SIG-ibmcloud has mainly focused on SIG set up, sharing IBM Clouds ongoing Kubernetes work like scalability tests, Kubernetes upgrade strategy etc. with the SIG members and start working on processes to move cloud provider code to a public GitHub repo.

### SIG-instrumentation

  * OOM parser uses kmsg
  * Add hugepages support
  * Add CRI-O support

* Sharing a PID namespace between containers in a pod is disabled by default in version 1.8. To enable for a node, use the `--docker-disable-shared-pid=false` kubelet flag. Be aware that PID namespace sharing requires Docker version greater than or equal to 1.13.1.

* Fix issues related to the eviction manager.

- Pod process namespace sharing is now Generally Available. The `PodShareProcessNamespace` feature gate is now deprecated and will be removed in Kubernetes 1.19. ([#84356](https://github.com/kubernetes/kubernetes/pull/84356), [@verb](https://github.com/verb))

installation, upgrade and configuration even more robust has been a major focus for this cycle for SIG Cluster Lifecycle (see the May 6, 2019 [Community Update](https://docs.google.com/presentation/d/1QUOsQxfEfHlMq4lPjlK2ewQHsr9peEKymDw5_XwZm8Q/edit?usp=sharing)). Bug fixes across bare metal tooling and production-ready user stories, such as the high availability use cases have been given priority for 1.15.

kubeadm, the cluster lifecycle building block, continues to receive features and stability...

- Forbidden sysctls for pod sharing the respective namespaces with the host are now checked when creating or updating pods without such sysctls. ([#118705](https://github.com/kubernetes/kubernetes/pull/118705), [@pacoxu](https://github.com/pacoxu))

### Failing Test

- Reverted the change to "support sharing waitingPods across different scheduler profiles". ([#124001](https://github.com/kubernetes/kubernetes/pull/124001), [@kerthcet](https://github.com/kerthcet))

### Bug or Regression

* Sharing a PID namespace between containers in a pod is disabled by default in 1.8. To enable for a node, use the --docker-disable-shared-pid=false kubelet flag. Note that PID namespace sharing requires docker >= 1.13.1. ([#51634](https://github.com/kubernetes/kubernetes/pull/51634), [@verb](https://github.com/verb))

- Add --permit-address-sharing flag to `kube-apiserver` to listen with `SO_REUSEADDR`. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoids waiting for the kernel to release socket in `TIME_WAIT` state, and hence, considerably reducing `kube-apiserver`...

- Allow cross-compilation of kubernetes on different platforms. ([#94403](https://github.com/kubernetes/kubernetes/pull/94403), [@bnrjee](https://github.com/bnrjee)) [SIG Release]
- Azure: Support multiple services sharing one IP address ([#94991](https://github.com/kubernetes/kubernetes/pull/94991), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
