Kubernetes 1.8.9-beta.0 和 1.8.8，容器集群管理系统

容器集群管理系统发布了 1.8.9-beta.0 和 1.8.8 版本，1.8.8 有以下值得关注的更新：

• Configurable etcd quota backend bytes in GCE (#59259, @wojtek-t)
• Cluster Autoscaler 1.0.4 (#59271, @mwielgus)
• Prevent kubelet from getting wedged if initialization of modules returns an error. (#59020, @brendandburns)
• Updates Calico version to v2.6.7 (Fixed a bug where Felix would crash when parsing a NetworkPolicy with a named port. See https://github.com/projectcalico/calico/releases/tag/v2.6.7) (#59130, @caseydavenport)
• Configurable etcd compaction frequency in GCE (#59106, @wojtek-t)
• [GCE] Apiserver uses InternalIP as the most preferred kubelet address type by default. (#59019, @MrHohn)
• Updated priority of mirror pod according to PriorityClassName. (#58485, @k82cn)
• Fix kubelet to correctly umounts mount points for glusterfs when transport endpoint is not connected and nfs when there is a stale file handle (#58660, @humblec)
• Detach and clear bad disk URI (#58345, @rootfs)
• Expose Metrics Server metrics via /metric endpoint. (#57456, @kawych)
• Access to externally managed IP addresses via the kube-apiserver service proxy subresource is no longer allowed by default. This can be re-enabled via the ServiceProxyAllowExternalIPs feature gate, but will be disallowed completely in 1.11 (#57265, @brendandburns)
• Add apiserver metric for number of requests dropped because of inflight limit. (#58340, @gmarek)
• Add apiserver metric for current inflight-request usage. (#58342, @gmarek)
• Update Calico version to v2.6.6 (#58482, @tmjd)
• Correctly handle transient connection reset errors on GET requests from client library. (#58520, @porridge)
• Fixes an issue where the resourceVersion of an object in a DELETE watch event was not the resourceVersion of the delete itself, but of the last update to the object. This could disrupt the ability of clients clients to re-establish watches properly. (#58547, @liggitt)
• Fix a bug affecting nested data volumes such as secret, configmap, etc. (#57422, @joelsmith)
• Fix garbage collection and resource quota when the controller-manager uses –leader-elect=false (#57340, @jmcmeek)
• Fixed encryption key and encryption provider rotation (#58375, @liggitt)
