# The Ubuntu scripting supports two ways of networking: Flannel and
# CNI.  To use CNI: (1) put a CNI configuration file, whose basename
# is the configured network type plus ".conf", somewhere on the driver
# machine (the one running `kube-up.sh`) and set CNI_PLUGIN_CONF to a
# pathname of that file, (2) put one or more executable binaries on
# the driver machine and set CNI_PLUGIN_EXES to a space-separated list
# of their pathnames, and (3) set CNI_KUBELET_TRIGGER to identify an
# appropriate service on which to trigger the start and stop of the
# kubelet on non-master machines.  For (1) and (2) the pathnames may
# be relative, in which case they are relative to kubernetes/cluster.
# If either of CNI_PLUGIN_CONF or CNI_PLUGIN_EXES is undefined or has
# a zero length value then Flannel will be used instead of CNI.
