|
|
# machine (the one running `kube-up.sh`) and set CNI_PLUGIN_CONF to a

|
|
# 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.
