# Configmap 'k-vswitch' is the only resource in this file that requires
# updates based on your cluster configuration.
#
# clusterCIDR should be updated to the same CIDR configured on your
#    Kubernetes components
# serviceCIDR should be updated to the same CIDR configured on your
#    Kubernetes components
# overlayType should be updated based on the overlay type you want.
#    Currently 'vxlan' and 'gre' are supported. 'gre' is recommended
#    but some cloud providers may not allow gre traffic over your network.
