etcd

修改 /etc/etcd/etcd.conf:

ETCD_LISTEN_CLIENT_URLS="http://10.31.166.39:2379"

flannel

创建 flannel-config.json 文件：

{
  "Network": "10.20.0.0/16",
  "SubnetLen": 24,
  "Backend": {
    "Type": "vxlan",
    "VNI": 1
  }
}

写入 etcd :

# etcdctl --no-sync --endpoints "http://10.31.166.39:2379" set /atomic.io/network/config < flannel-config.json                                                                                       
{
  "Network": "10.20.0.0/16",
  "SubnetLen": 24,
  "Backend": {
    "Type": "vxlan",
    "VNI": 1
