cluster-autoscaler.spec

#
# This is a template package spec that will support Go builds following the OpenShift conventions.
# It expects a set of standard env vars that define the Git version being built and can also handle
# multi-architecture Linux builds. It has stubs for cross building.

# Search for TODO and fill those sections out as appropriate.

### AUTO-BUNDLED-GEN-ENTRY-POINT

%description
Cluster Autoscaler is a component that automatically adjusts
the size of a Kubernetes/OpenShift cluster so that all pods
have a place to run and there are no unneeded nodes.
