docker flannel k8s1 yum安裝flannel包： yum install flannel -y
[root@master ~]# etcdctl get /coreos.com/network/subnets/10.1.39.0-24
{"PublicIP":"192.168.233.129"}
[root@master ~]# etcdctl get /coreos.com/network/config
{ "Network": "10.1.0.0/16" }
[root@master ~]#
2 編輯配置文件
vim /etc/sysconfig/flanneld
FLANNEL_ETCD_ENDPOINTS="http://192.168.233.130:2379"
FLANNEL_ETCD_PREFIX="/coreos.com/network"
#FLANNEL_OPTIONS=""
3 flannel網絡依賴etcd存儲，啟動flanneld服務前需在etcd存儲裏添加配置：
etcdctl set /coreos.com/network/config ‘{ "Network": "10.1.0.0/16" }‘
4 啟動flanneld服務前必須先關閉docker服務：
systemctl stop docker
systemctl start flanneld
5 flanneld服務會通過執行腳本mk-docker-opts.sh在目錄/run/flannel下面生成兩個文件。
/run/flannel/docker
/run/flannel/subnet.env
/usr/lib/systemd/system/docker.service.d/flannel.conf指向/run/flannel/docker
6 systemctl start docker:
7 查看etcd：
[root@master ~]# etcdctl get /coreos.com/network/subnets/10.1.95.0-24
[root@master ~]# etcdctl get /coreos.com/network/subnets/10.1.39.0-24
{"PublicIP":"192.168.233.129"}
[root@master ~]# etcdctl get /coreos.com/network/config
{ "Network": "10.1.0.0/16" }
[root@master ~]#
