### 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.

  // List of sources to populate environment variables in the container.
  // The keys defined within a source must be a C_IDENTIFIER. All invalid keys
  // will be reported as an event when the container is starting. When a key exists in multiple
  // sources, the value associated with the last source will take precedence.
  // Values defined by an Env with a duplicate key will take precedence.
  // Cannot be updated.
  // +optional

- Reduce API server memory when many CRDs are loaded by sharing a single etcd3 client logger across all clients ([#111650](https://github.com/kubernetes/kubernetes/pull/111650), [@negz](https://github.com/negz)) [SIG API Machinery]

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...

- 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`...

* API: the metadata.selfLink field is deprecated in individual and list objects. It will no longer be returned starting in v1.20, and the field will be removed entirely in v1.21. ([#80978](https://github.com/kubernetes/kubernetes/pull/80978), [@wojtek-t](https://github.com/wojtek-t))

- The EndpointSlice controller now waits for EndpointSlice and Node caches to be synced before starting. ([#94086](https://github.com/kubernetes/kubernetes/pull/94086), [@robscott](https://github.com/robscott)) [SIG Apps and Network]
- Upon successful authorization check, an impersonated user is added to the system:authenticated group.

- 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]

<p>
A set of files sharing the same PackageName form the implementation of a package.
An implementation may require that all source files for a package inhabit the same directory.
