六.kubernets(k8s) 1.4.0 部署

1.准备

• 下载kubernetes版本：1.4.0
• https://github.com/kubernetes/kubernetes/releases

[在master节点]

1.1.解压二进制包

tar xf kubernetesv1.4.0.tar.gz
cd kubernetes/server/

1.2.解压master所需的安装包

tar xf kubernetes-server-linux-amd64.tar.gz
cd kubernetes/server/bin/

1.3.把master需要的程序，拷贝到/usr/bin下，也可以设置环境变量达到相同目的

cp kube-apiserver kube-controller-manager kubectl kube-scheduler /usr/bin/

1.4.把minion需要的程序，scp发送到minion上

scp kubelet kube-proxy k8s_minion_ip:/usr/bin/

2.部署

[在master节点]

2.1.创建脚本

vim start_k8s_master.sh

#!/bin/bash

#firstly, start etcd
systemctl restart etcd

#secondly, start flanneld
systemctl restart flanneld

#then, start docker
systemctl restart docker

#start the main server of k8s master
nohup kube-apiserver --insecure-bind-address=0.0.0.0 --insecure-port=8080 --cors_allowed_origins=.* --etcd_servers=http://127.0.0.1:2379 --v=1 --logtostderr=false --log_dir=/var/log/k8s/apiserver --service-cluster-ip-range=172.100.0.0/16 &

nohup kube-controller-manager --master=k8s_master_ip:8080 --enable-hostpath-provisioner=false --v=1 --logtostderr=false --log_dir=/var/log/k8s/controller-manager &

nohup kube-scheduler --master=k8s_master_ip:8080 --v=1 --logtostderr=false --log_dir=/var/log/k8s/scheduler &

2.2.授权

chmod a+x start_k8s_master.sh

2.3.创建日志目录

mkdir -p /var/log/k8s/apiserver
mkdir -p /var/log/k8s/controller-manager
mkdir -p /var/log/k8s/scheduler

[在minion节点]

2.4.创建脚本

vim start_k8s_minion.sh

#!/bin/bash

#firstly, start etcd
systemctl restart etcd

#secondly, start flanneld
systemctl restart flanneld

#then, start docker
systemctl restart docker

#start the minion
nohup kubelet --address=0.0.0.0 --port=10250 --v=1 --log_dir=/var/log/k8s/kubelet --hostname_override=k8s_minion_ip --api_servers=http://k8s_master_ip:8080 --logtostderr=false &

nohup kube-proxy --master=k8s_master_ip:8080 --log_dir=/var/log/k8s/proxy --v=1 --logtostderr=false &

2.5.授权

chmod a+x start_k8s_minion.sh

2.6.创建日志目录

mkdir -p /var/log/k8s/kubelet
mkdir -p /var/log/k8s/proxy

3.运行k8s

[在master节点]

./start_k8s_master.sh

[在minion节点]

./start_k8s_minion.sh
