kubernetes集群网络配置方案——flannel部署
部署环境： CentOS Linux release 7.2 64位 10.10.0.103 node01 10.10.0.49 node02 安装过程： # yum install flannel # tar zxfflannel-v0.8.0-linux-amd64_.tar.gz # cpflanneld /usr/bin/ # cpmk-docker-opts.sh /usr/bin/ 编辑服务配置文件： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 #cat/usr/lib/systemd/system/flanneld.service [Unit] Description=flanneldoverlayaddressetcdagent After=network.target Before=docker.service [Service] Type=notify EnvironmentFile= /etc/sysconfig/flannel ExecStart= /usr/bin/flanneld -etcd-endpoints=${FLANNEL_ETCD}$FLANNEL_OPTIONS [Install] RequiredBy=docker.service WantedBy=multi-user.target 编辑配置文件： 1 2 3 #cat/etc/sysconfig/flannel FLANNEL_ETCD= "http://10.10.0.103:2379,http://10.10.0.49:2379" FLANNEL_ETCD_KEY= "/coreos.com/network" 在etcd库中添加一条网络配置信息，flannel用来分配docker的虚拟ip地址段： # etcdctl set /coreos.com/network/config # etcdctl get /coreos.com/network/config { "Network": "10.1.0.0/16" } # systemctl start flanneld # mk-docker-ops.sh -i # source /run/flannel/subnet.env # ifconfig docker0 ${FLANNEL_SUBMENT} #ifconfig 查看docker网卡ip 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 docker0:flags=4163<UP,BROADCAST,RUNNING,MULTICAST>mtu1500 inet10.1.8.1netmask255.255.255.0broadcast10.1.8.255 ether02:42:bf:cb:f1:fftxqueuelen0(Ethernet) RXpackets40369bytes8671191(8.2MiB) RXerrors0dropped0overruns0frame0 TXpackets40663bytes3818695(3.6MiB) TXerrors0dropped0overruns0carrier0collisions0 eth0:flags=4163<UP,BROADCAST,RUNNING,MULTICAST>mtu1500 inet10.10.0.103netmask255.255.0.0broadcast10.10.255.255 ether00:16:3e:08:93:f7txqueuelen1000(Ethernet) RXpackets2033352bytes695497718(663.2MiB) RXerrors0dropped0overruns0frame0 TXpackets1378035bytes2166169069(2.0GiB) TXerrors0dropped0overruns0carrier0collisions0 flannel0:flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>mtu1472 inet10.1.8.0netmask255.255.0.0destination10.1.8.0 unspec00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00txqueuelen500(UNSPEC) RXpackets6bytes504(504.0B) RXerrors0dropped0overruns0frame0 TXpackets6bytes504(504.0B) TXerrors0dropped0overruns0carrier0collisions0 另一个节点同样重复以上安装步骤。 本文转自 baiying 51CTO博客，原文链接：http://blog.51cto.com/baiying/1967156，如需转载请自行联系原作者
