k8s-2(Flanne网络)

1、写入分配的子网段到etcd，供flanneld使用

[root@linux-node1 ssl]# pwd
/opt/etcd/ssl
[root@linux-node1 ssl]# /opt/etcd/bin/etcdctl --ca-file=ca.pem --cert-file=server.pem --key-file=server-key.pem https://192.168.56.11:2379,https://192.168.56.12:2379,https://192.168.56.13:2379 set /coreos.com/network/config '{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}'
No help topic for 'https://192.168.56.11:2379,https://192.168.56.12:2379,https://192.168.56.13:2379'
[root@linux-node1 ssl]# /opt/etcd/bin/etcdctl --ca-file=ca.pem --cert-file=server.pem --key-file=server-key.pem --endpoints="https://192.168.56.11:2379,https://192.168.56.12:2379,https://192.168.56.13:2379" set /coreos.com/network/config '{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}'

{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}
