Known issues

• exec liveness/readiness probes leak resources due to Docker exec leaking resources (#10659)
• docker load sometimes hangs which causes the kube-apiserver not to start. Restarting the Docker daemon should fix the issue (#10868)
• The kubelet on the master node doesn't register with the kube-apiserver so statistics aren't collected for master daemons (#10891)
• Heapster and InfluxDB both leak memory (#10653)
• Wrong node cpu/memory limit metrics from Heapster (kubernetes-retired/heapster#399)
• Services that set type=LoadBalancer can not use port 10250 because of Google Compute Engine firewall limitations
• Add-on services can not be created or deleted via kubectl or the Kubernetes API (#11435)
• If a pod with a GCE PD is created and deleted in rapid succession, it may fail to attach/mount correctly leaving PD data inaccessible (or corrupted in the worst case). (http://issue.k8s.io/11231#issuecomment-122049113)
  • Suggested temporary work around: introduce a 1-2 minute delay between deleting and recreating a pod with a PD on the same node.
• Explicit errors while detaching GCE PD could prevent PD from ever being detached (#11321)
• GCE PDs may sometimes fail to attach (#11302)
• If multiple Pods use the same RBD volume in read-write mode, it is possible data on the RBD volume could get corrupted. This problem has been found in environments where both apiserver and etcd rebooted and Pods were redistributed.
  • A workaround is to ensure there is no other Ceph client using the RBD volume before mapping RBD image in read-write mode. For example, rados -p poolname listwatchers image_name.rbd can list RBD clients that are mapping the image.
