配置flanneld

shell>#vi /etc/sysconfig/flanneld 

  1. # Flanneld configuration options
  3. # etcd url location.  Point this to the server where etcd runs
  4. FLANNEL_ETCD_ENDPOINTS="http://etcd1.k8s.com:2379,http://etcd2.k8s.com:2379,http://etcd3.k8s.com:2379;"
  6. # etcd config key.  This is the configuration key that flannel queries
  7. # For address range assignment
  8. FLANNEL_ETCD_PREFIX="/flannel/network"
  10. # Any additional options that you want to pass
  11. #FLANNEL_OPTIONS=""
