本文详细介绍如何使用两台CentOS 7.2虚拟机部署Kubernetes集群，包括管理节点和服务器节点的配置步骤，如安装Etcd、Kubernetes Master组件及Node组件等。

k8s架构图

环境介绍

本次部署使用两台centos7.2虚拟机，最小化安装，一台作为管理节点，一台作为服务节点，均关闭selinux和firewalld服务

主机	服务
k8s-master	apiserver,controller-manager,scheduler,etcd
k8s-node1	docker,kubelet,kube-proxy,flannel

10.10.84.112    k8s-node1
10.10.84.111    k8s-master k8s-etcd

部署k8s-master：

安装etcd

[root@k8s-master ~]# yum install -y etcd-3.1.9-2.el7.x86_64
[root@k8s-master ~]# vim /etc/etcd/etcd.conf
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://k8s-etcd:2379"
[root@k8s-master ~]# etcdctl --endpoints http://10.10.84.111:2379 set /atomic.io/network/config '{"Network":"172.17.0.0/16"}'
[root@k8s-master ~]# systemctl enable etcd
[root@k8s-master ~]# systemctl restart etcd

安装kubernets-master

[root@k8s-master ~]# yum -y install kubernetes-master-1.5.2-0.7
[root@k8s-master ~]# vim /etc/kubernetes/apiserver
KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"
KUBE_ETCD_SERVERS="--etcd-servers=http://k8s-etcd:2379"
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,ResourceQuota"
[root@k8s-master ~]# vim /etc/kubernetes/config
KUBE_MASTER="--master=http://k8s-master:8080"
[root@k8s-master ~]# systemctl enable kube-apiserver kube-scheduler kube-controller-manager
[root@k8s-master ~]# systemctl start kube-apiserver kube-scheduler kube-controller-manager

测试k8s-master，返回json描述信息

部署k8s-node

安装docker

[root@k8s-node1 ~]# yum install docker-1.12.6-48.git0fdc778.el7.centos.x86_64
[root@k8s-node1 ~]# systemctl enable docker
[root@k8s-node1 ~]# systemctl start docker

安装flannel

[root@k8s-node1 ~]# yum install flannel-0.7.1-2.el7
[root@k8s-node1 ~]# vim /etc/sysconfig/flanneld
FLANNEL_ETCD_ENDPOINTS="http://k8s-etcd:2379"
FLANNEL_ETCD_PREFIX="/atomic.io/network"
[root@k8s-node1 ~]# systemctl enable flanneld
[root@k8s-node1 ~]# systemctl start flanneld

安装kubernetes-node

[root@k8s-node1 ~]# yum install kubernetes-node-1.5.2-0.7.git269f928.el7.x86_64
[root@k8s-node1 ~]# vim /etc/kubernetes/config
KUBE_MASTER="--master=http://k8s-master:8080"
[root@k8s-node1 ~]# vim /etc/kubernetes/kubelet
KUBELET_HOSTNAME="--hostname-override=k8s-node1"
KUBELET_API_SERVER="--api-servers=http://k8s-master:8080"
[root@k8s-node1 ~]# systemctl enable kubelet kube-proxy
[root@k8s-node1 ~]# systemctl start kubelet kube-proxy

测试

[root@k8s-master ~]# kubectl get node
NAME        STATUS    AGE
k8s-node1   Ready     5m
