三、Kubernetes_V1.10集群部署-master-部署flanne网络

1.

etcdctl --ca-file=/etc/etcd/ssl/ca.pem --cert-file=/etc/etcd/ssl/server.pem --key-file=/etc/etcd/ssl/server-key.pem --endpoints="https://172.18.6.39:2379,https://172.18.6.40:2379,https://172.18.6.41:2379" set /coreos.com/network/config '{ "Network": "172.31.0.0/16", "Backend": {"Type": "vxlan"}}'

2.生成flannel启动文件

cat > /usr/lib/systemd/system/flanneld.service <<EOF
[Unit]
Description=Flanneld overlay address etcd agent
After=network-online.target network.target
Before=docker.service

[Service]
Type=notify
EnvironmentFile=/etc/kubernetes/flanneld
ExecStart=/usr/bin/flanneld --ip-masq \$FLANNEL_OPTIONS
ExecStartPost=/usr/bin/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/subnet.env
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF

3.生成flannel配置文件

cat >/etc/kubernetes/flanneld<<EOF
FLANNEL_OPTIONS="--etcd-endpoints=https://172.18.6.39:2379,https://172.18.6.40:2379,https://172.18.6.41:2379 -etcd-cafile=/etc/etcd/ssl/ca.pem -etcd-certfile=/etc/etcd/ssl/server.pem -etcd-keyfile=/etc/etcd/ssl/server-key.pem"
EOF

4.启动flannel

5.修改docker配置文件

（1）修改启动文件

vim /usr/lib/systemd/system/docker.service
#Add envionment#
EnvironmentFile=/run/flannel/subnet.env #添加
ExecStart=/usr/bin/dockerd --graph=/opt/docker $DOCKER_NETWORK_OPTIONS #修改

（2）修改配置文件

cd /etc/docker/
cp daemon.json daemon.json_bak

systemctl daemon-reload
systemctl restart docker
