1. 整体结构图
版本信息
- Kubernetes-1.2
- docker-1.9.0
- flannel-0.5.3
- etcd-2.1.1
2. kubernetes环境部署
- Master:172.16.198.129
- Slave: 172.16.198.128
两台虚拟机准备工作:
- 每台机器禁用firewalld：
systemctl stop firewalld
systemctl disable firewalld- 禁用selinux：
# vi /etc/selinux/config
# SELINUX=enforcing
SELINUX=disabled也可用命令
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config2.1 Master机器安装与配置
#yum -y install etcd kubernetes#vi /etc/etcd/etcd.conf
ETCD_NAME=default
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"

KUBE_LOG_LEVEL="--v=0"
KUBE_ALLOW_PRIV="--allow_privileged=false"
KUBE_MASTER="--master=http://172.16.198.129:8080"启动服务:
for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler; do
systemctl restart $SERVICES
systemctl enable $SERVICES
systemctl status $SERVICES
done定义flannel网络配置到etcd,这个配置会推送到各个Slave的flannel服务上
etcdctl mk /coreos.com/network/config '{"Network":"172.17.0.0/16"}'2.2 Slave:机器的安装与配置
安装docker并更新重启
#yum -y install docker
#yum -y update
#reboot#yum -y install kubernetes-node flannel# vi /etc/kubernetes/config

FLANNEL_ETCD="http://172.16.198.129:2379"
FLANNEL_ETCD_KEY="/coreos.com/network"启动服务
for SERVICES in kube-proxy kubelet docker flanneld; do
systemctl restart $SERVICES
systemctl enable $SERVICES
systemctl status $SERVICES
done登陆master，确认minions的状态：
[root@master ~]# kubectl get nodes
