## Known Issues
|
|
|
|
This document summarizes known issues with existing Kubernetes releases.
|

|
|
Please consult this document before filing new bugs.

|
### Release 1.0.1
|
|
|
|
* `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 (https://github.com/GoogleCloudPlatform/heapster/issues/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.
