参考文档中的问题

在部署flannal网络，etcd注册网段时

• 原文

[root@elasticsearch02 cfg]# /k8s/etcd/bin/etcdctl --ca-file=/k8s/etcd/ssl/ca.pem --cert-file=/k8s/etcd/ssl/server.pem --key-file=/k8s/etcd/ssl/server-key.pem --endpoints="https://10.2.8.44:2379,https://10.2.8.65:2379,https://10.2.8.34:2379"  set /k8s/network/config  '{ "Network": "10.254.0.0/16", "Backend": {"Type": "vxlan"}}'
{ "Network": "10.254.0.0/16", "Backend": {"Type": "vxlan"}}

• flanneld 当前版本 (v0.10.0) 不支持 etcd v3，故使用 etcd v2 API 写入配置 key 和网段数据，但etcd默认使用v3的API，故需修改为

[root@cn7180 bin]# ETCDCTL_API=2 /k8s/etcd/bin/etcdctl --ca-file=/k8s/etcd/ssl/ca.pem --cert-file=/k8s/etcd/ssl/server.pem --key-file=/k8s/etcd/ssl/server-key.pem --endpoints="http://172.29.122.34:2379,http://172.29.122.35:2379,http://172.29.122.36:2379"  set /k8s/network/config  '{ "Network": "10.254.0.0/16", "Backend": {"Type": "vxlan"}}'
{ "Network": "10.254.0.0/16", "Backend": {"Type": "vxlan"}}
