kubernetes部署-flanneld  

flanneld v0.10.0 版本部署部署

操作节点node、node1、node2

安装部署

cd /data/ssl/etcd/
#创建容器所使用的网络地址段

/opt/etcd/bin/etcdctl \
--ca-file=ca.pem --cert-file=server.pem --key-file=server-key.pem \
--endpoints="https://10.167.130.205:2379,https://10.167.130.206:2379,https://10.167.130.210:2379" \
set /coreos.com/network/config  '{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}'

下载软件包添加服务以及配置文件

cd /data/src/

wget https://github.com/coreos/flannel/releases/download/v0.10.0/flannel-v0.10.0-linux-amd64.tar.gz

mkdir /opt/kubernetes/bin -p
tar xf flannel-v0.10.0-linux-amd64.tar.gz
mv flanneld mk-docker-opts.sh  /opt/kubernetes/bin/

mkdir  /opt/kubernetes/cfg 


vim /opt/kubernetes/cfg/flanneld

检查

ps -ef |grep docker  #检查进程是否启动
ip addr #查看ip地址

确保docker0与flannel.1在同一网段。
测试不同节点互通，在当前节点访问另一个Node节点docker0 IP
如果能通说明Flannel部署成功。如果不通检查下日志：journalctl -u flannel
