Automatic merge from submit-queue Add EmptyDir volume capacity isolation This PR adds the support for isolating the emptyDir volume use. If user sets a size limit for emptyDir volume, kubelet's eviction manager monitors its usage and evict the pod if the usage exceeds the limit. This feature is part of local storage capacity isolation and described in the proposal kubernetes/community#306 **Release note**: ```release-note Alpha feature: allows users to set storage limit to isolate EmptyDir volumes. It enforces the limit by evicting pods that exceed their storage limits ```
This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.
Most code in the staging/ directory is authoritative, i.e. the only copy of
the code. You can directly modify such code. However the packages in
staging/src/k8s.io/client-go/pkg are copied from pkg/. If you modify the
original code in pkg/, you need to run hack/godep-restore.sh from the k8s
root directory, followed by hack/update-staging-client-go.sh. We are working
towards making all code in staging/ authoritative.
The vendor/k8s.io directory contains symlinks pointing to this staging area,
so to use a package in the staging area, you can import it as
k8s.io/<package-name>, as if the package were vendored. Packages will be
vendored from k8s.io/<package-name> for real after the test matrix is
converted to vendor k8s components.
