saadali	542f2dc708	Introduce new kubelet volume manager ... This commit adds a new volume manager in kubelet that synchronizes volume mount/unmount (and attach/detach, if attach/detach controller is not enabled). This eliminates the race conditions between the pod creation loop and the orphaned volumes loops. It also removes the unmount/detach from the `syncPod()` path so volume clean up never blocks the `syncPod` loop.	2016-06-15 09:34:08 -07:00
Saad Ali	9dbe943491	Attach/Detach Controller Kubelet Changes ... This PR contains Kubelet changes to enable attach/detach controller control. * It introduces a new "enable-controller-attach-detach" kubelet flag to enable control by controller. Default enabled. * It removes all references "SafeToDetach" annoation from controller. * It adds the new VolumesInUse field to the Node Status API object. * It modifies the controller to use VolumesInUse instead of SafeToDetach annotation to gate detachment. * There is a bug in node-problem-detector that causes VolumesInUse to get reset every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9 opened to fix that.	2016-06-02 16:47:11 -07:00
saadali	92500a20d7	Attach detach controller business logic added ... Split controller cache into actual and desired state of world. Controller will only operate on volumes scheduled to nodes that have the "volumes.kubernetes.io/controller-managed-attach" annotation.	2016-05-24 23:01:16 -07:00
