# Now we're running in the sidecar container
# /etc/kubernetes/addons holds the data in the hyperkube container
# /srv/kubernetes is an emptyDir that maps to /etc/kubernetes in the addon-manager container
# This way we're using the latest manifests from hyperkube without updating
# kube-addon-manager which is used for other deployments too

# Inside /etc/kubernetes/addons, there are two directories: singlenode and multinode
# If "singlenode" is passed to this script; those manifests are copied to the addon-manager and vice versa with "multinode"
SUBDIRECTORY=$1

# While there is no data copied over to the emptyDir, try to copy it.
