CentOS7安装kubernetes V1.0版本

3212ed

组件版本如下：

   
1.Kubernetes-1.0
2.docker-1.8.0
3.flannel-0.5.3
4.etcd-2.1.1


kubernetes环境部署:

   
1.Master:172.16.198.129
2.Slave: 172.16.198.128


两台虚拟机准备工作:

1.每台机器禁用firewalld：

   
systemctl stop firewalld
systemctl disable firewalld


2.禁用selinux：

   
vi /etc/selinux/config
#SELINUX=enforcing  
SELINUX=disabled
#也可用命令
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config


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"
ETCD_ADVERTISE_CLIENT_URLS="


   
vi /etc/kubernetes/apiserver
KUBE_API_ADDRESS="--address=0.0.0.0"
KUBE_ETCD_SERVERS="--etcd_servers=http://172.16.198.129:2379"
KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"
KUBE_ADMISSION_CONTROL="--admission_control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"
KUBE_API_ARGS=""


   
vi /etc/kubernetes/controller-manager
KUBE_CONTROLLER_MANAGER_ARGS="--node-monitor-grace-period=10s --pod-eviction-timeout=10s"


   
vi /etc/kubernetes/config
KUBE_LOGTOSTDERR="--logtostderr=true"
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"}'


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
KUBE_LOGTOSTDERR="--logtostderr=true"
KUBE_LOG_LEVEL="--v=0"
KUBE_ALLOW_PRIV="--allow_privileged=false"
KUBE_MASTER="--master=http://172.16.198.129:8080"


   
vi /etc/kubernetes/kubelet
KUBELET_ADDRESS="--address=127.0.0.1"
KUBELET_HOSTNAME="--hostname_override=172.16.198.128"
KUBELET_API_SERVER="--api_servers=http://172.16.198.129:8080"
KUBELET_ARGS="--pod-infra-container-image=kubernetes/pause"


   
vi /etc/sysconfig/flanneld
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：

   
[iyunv@master ~]# kubectl get nodes
NAME             LABELS                                  STATUS
172.16.198.128   kubernetes.io/hostname=172.16.198.128   Ready


注：如果需要多台Slave节点，只需要重复上面slava机器上的操作。
