Unknown admission plugin: DefaultTolerationSeconds

[niyanchun]

I install Kubernetes on Ubuntu 14.04, and I git clone the master branch, in kubernetes/cluster/ubuntu/config-default.sh, there is a config:

export ADMISSION_CONTROL=NamespaceLifecycle,LimitRanger,ServiceAccount,DefaultStorageClass,DefaultTolerationSeconds,ResourceQuota

but kube-apiserver doesn't know DefaultTolerationSeconds.

@niyanchun how did you install Kubernetes? The DefaultTolerationSeconds admission plugin referenced in the master version of the install scripts does not exist in the 1.5.x version

@calebamiles not a blocker, CI is testing this plugin

@liggitt I installed Kubernetes following this manual: https://kubernetes.io/docs/getting-started-guides/ubuntu/manual/, and add v1.5.5 to the $KUBE_ROOT/version file (#39224). I commented the DefaultTolerationSeconds and installed successfully.

I would recommend using the scripts from the v1.5.5 tag to accompany the v1.5.5 you have installed. Master scripts include features that do not exist yet in a released version.
