41ed85479a move predicates into library (address #12744) 
DONE:
1. refactor all predicates: predicates return fitOrNot(bool) and error(Error) in which the latter is of type
	PredicateFailureError or InsufficientResourceError. (For violation of either MaxEBSVolumeCount or
        MaxGCEPDVolumeCount, returns one same error type as ErrMaxVolumeCountExceeded)
2. GeneralPredicates() is a predicate function, which includes serveral other predicate functions (PodFitsResource,
        PodFitsHost, PodFitsHostPort). It is registered as one of the predicates in DefaultAlgorithmProvider, and
        is also called in canAdmitPod() in Kubelet and should be called by other components (like rescheduler, etc)
        if necessary. See discussion in issue #12744
3. remove podNumber check from GeneralPredicates
4. HostName is now verified in Kubelet's canAdminPod(). add TestHostNameConflicts in kubelet_test.go
5. add getNodeAnyWay() method in Kubelet to get node information in standaloneMode

TODO:
1. determine which predicates should be included in GeneralPredicates()
2. separate GeneralPredicates() into:
	a. GeneralPredicatesEvictPod() and
	b. GeneralPredicatesNotEvictPod()
3. DaemonSet should use GeneralPredicates()

8a952748a1 Merge pull request #22942 from jsafrane/devel/aws-more-devices 
Allow up to 39 PVs attached to AWS node
 2016-03-15 12:41:15 -07:00
Jan Safranek
f270cb1b9b Allow 39 atached EBS devices. 
AWS has soft support limit for 40 attached EBS devices. Assuming there is just
one root device, use the rest for persistent volumes.

The devices will have name /dev/xvdba - /dev/xvdcm, leaving /dev/sda - /dev/sdz
to the system.

Also, add better error handling and propagate error
"Too many EBS volumes attached to node XYZ" to a pod.

9236e4a0b4 scheduler: change fit predicates and priority func as needed for optimization 2016-02-09 09:38:28 -08:00
Oleg Shaldybin
3a36dfb306 Minor selectHost optimization in scheduler 
Instead of sorting hosts by score, find max score and choose one of
the hosts with max score directly. Saves a little time on sorting and
avoids extra copying of HostPriorityList entries.

Test had to be updated as one of the test cases relied on having a
stable order from pre-sorting.
