215, node 节点的 docker-ce 的安装和 flanneld 搭建 (day215)
作者:互联网
1, 安装node 节点flanneld 网络。 1) 安装好dockers。 2) # step 1: 安装必要的一些系统工具 3) sudo yum install -y yum-utils device-mapper-persistent-data lvm2 4) # Step 2: 添加软件源信息 5) sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 6) # Step 3: 更新并安装 Docker-CE 7) sudo yum makecache fast 8) sudo yum -y install docker-ce 2)写入分配的子网段到etcd,供flanneld使用。(这句在master端 操作一次就可以了) #/opt/kubernetes/bin/etcdctl \ --ca-file=/opt/kubernetes/ssl/ca.pem --cert-file=/opt/kubernetes/ssl/server.pem --key-file=/opt/kubernetes/ssl/server-key.pem \ --endpoints="https://192.168.1.101:2379,https://192.168.1.102:2379,https://192.168.1.103:2379" \ set /coreos.com/network/config '{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}' // etcd 的集群地址为:https://192.168.0.211:2379,https://192.168.0.212:2379,https://192.168.0.213:2379 3) tar xf flanner.tar.gz cd flanner mv flanneld mk-docker-opts.sh /opt/kubernetes/cfg/ 4)先拷贝证书到ssl目录,创建flanneld文件。 [root@localhost cfg]# [root@localhost cfg]# vim flanneld FLANNEL_OPTIONS="--etcd-endpoints=https://192.168.132.157:2379,https://192.168.132.158:2379,https://192.168.132.159:2379 -etcd-cafile=/opt/kubernetes/ssl/ca.pem -etcd-certfile=/opt/kubernetes/ssl/server.pem -etcd-keyfile=/opt/kubernetes/ssl/server-key.pem" [root@localhost cfg]# pwd /opt/kubernetes/cfg [root@localhost cfg]# 5) [root@localhost cfg]# [root@localhost cfg]# cat /usr/lib/systemd/system/flanneld.service [Unit] Description=Flanneld overlay address etcd agent After=network-online.target network.target Before=docker.service [Service] Type=notify EnvironmentFile=/opt/kubernetes/cfg/flanneld ExecStart=/opt/kubernetes/bin/flanneld --ip-masq $FLANNEL_OPTIONS ExecStartPost=/opt/kubernetes/bin/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/subnet.env Restart=on-failure [Install] WantedBy=multi-user.target [root@localhost cfg]# systemctl start flanneld 6, 修改docker.service 使用flanner,添加箭头的行。
systemctl restart docker
