[**ubuntu部署kubeadm1.13.1高可用**][ubuntu_kubeadm1.13.1]

1.安装前准备

关闭selinux  防火墙  swap分区（否则在init初始化无法进行），准备工作较为基础此处不过多编写

$ vi /etc/sysctl.d/k8s-sysctl.conf net.bridge.bridge-nf-call\-iptables=1net.bridge.bridge-nf-call\-ip6tables=1 $ sysctl -p /etc/sysctl.d/k8s-sysctl.conf

2.安装docker

\#Ubuntu安装dcoker存储库

apt-get install -y apt-transport-https ca-certificates curl software-properties-common

\#添加Docker官方的GPG密钥

curl -fsSL [https://download.docker.com/linux/ubuntu/gpg][https_download.docker.com_linux_ubuntu_gpg] | sudo apt-key add -

\#设置stable存储库

add-apt-repository "deb \[arch=amd64\] [https://download.docker.com/linux/ubuntu][https_download.docker.com_linux_ubuntu] $(lsb\_release -cs) stable"

\#更新apt包索引

apt-get update

\#安装docker最新版本18.06

apt install docker-ce=18.06.0~ce~3-0~ubuntu

3.安装kubeadm，kubelet和kubectl（建议版本号与Kubernetes的版本匹配）

apt-get update && apt-getinstall \-y apt-transport-https curl

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

EOF

apt-get update

apt-get install -y kubelet kubeadm kubectl

4.配置主节点上的kubelet使用的cgroup驱动程序(小坑，前面版本的部署基本都没怎么配置docker驱动和kubelet都是一致的，这里忽略了导致后面出现的报错且日志中没有反馈这方面报错信息)

dcoker info查看下驱动，修改/etc/default/kubelet

我这里是cgroupfs ，保证驱动一致，多说一句很多文档对这里没有提到，1.13和以前在这里配置略微不同，老版本这里都是修改/etc/systemd/system/kubelet.service.d/10-kubeadm.conf配置就可以，kubelet默认驱动配置是system

cat /etc/defaule/kubelet

KUBELET\_EXTRA\_ARGS=--cgroup-driver=cgroupfs

需要重新启动kubelet

systemctl daemon-reload systemctl restart kubelet

5.在每台node上执行images

root@ubuntu:~\# vim /root/pull.sh

\#!/bin/bash

Tar\_List="k8s.gcr.io/kube-apiserver:v1.13.3

k8s.gcr.io/kube-controller-manager:v1.13.3

k8s.gcr.io/kube-proxy:v1.13.3

k8s.gcr.io/kube-scheduler:v1.13.3

k8s.gcr.io/coredns:1.2.6

k8s.gcr.io/etcd:3.2.24

k8s.gcr.io/pause:3.1

gcr.io/google\_containers/kubernetes-dashboard-amd64:v1.6.3"

docker pull quay.io/coreos/flannel:v0.10.0-amd64

docker pull quay.io/coreos/flannel:v0.10.0-arm

Tar\_ali\_Begin=registry.cn-hangzhou.aliyuncs.com/google\_containers

for Project in $\{Tar\_List\};do

echo "docker $\{Project\}"

Tar=$(echo $\{Project\}|awk -F/ '\{print $NF\}')

echo docker pull $\{Tar\_ali\_Begin\}/$\{Tar\}

docker pull $\{Tar\_ali\_Begin\}/$\{Tar\}

docker tag $\{Tar\_ali\_Begin\}/$\{Tar\} $\{Project\}

docker rmi $\{Tar\_ali\_Begin\}/$\{Tar\}

done

$hostnamectl set-hostname \`hostname\`

$/bin/bash /root/pull.sh

8.初始化init

kubeadm init --pod-network-cidr=10.244.0.0/16

初始化成功

保留token，已便后面添加节点用

kubeadm join --token <token> <master-ip>:<master-port> \--discovery-token-ca-cert-hash sha256:<hash>

kubeadm token list（可查看生成的token）

运行以下命令

mkdir \-p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config

\#部署网络Flanner

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

查看节点状态

kubectl get node

kubectl get pod --all-namespaces

这里master节点安装完成，如果pod状态不是running查看系统日志或者使用kubectl describe pod –n kube-system+pod名查看

9.将证书文件从第一个master节点复制到其余master节点,集群etcd采用的是http没有加证书

USER=root \# customizable CONTROL\_PLANE\_IPS="172.16.10.2 172.16.10.3"for host in$\{CONTROL\_PLANE\_IPS\}; do scp /etc/kubernetes/pki/ca.crt "$\{USER\}"@$host: scp /etc/kubernetes/pki/ca.key "$\{USER\}"@$host: scp /etc/kubernetes/pki/sa.key "$\{USER\}"@$host: scp /etc/kubernetes/pki/sa.pub "$\{USER\}"@$host: scp /etc/kubernetes/pki/front-proxy-ca.crt "$\{USER\}"@$host: scp /etc/kubernetes/pki/front-proxy-ca.key "$\{USER\}"@$host: \#scp /etc/kubernetes/pki/etcd/ca.crt "$\{USER\}"@$host:etcd-ca.crt\#scp /etc/kubernetes/pki/etcd/ca.key "$\{USER\}"@$host:etcd-ca.key scp /etc/kubernetes/admin.conf "$\{USER\}"@$host: done

其他master节点操作

USER=root \# customizable mkdir -p /etc/kubernetes/pki/etcd mv /home/$\{USER\}/ca.crt /etc/kubernetes/pki/ mv /home/$\{USER\}/ca.key /etc/kubernetes/pki/ mv /home/$\{USER\}/sa.pub /etc/kubernetes/pki/ mv /home/$\{USER\}/sa.key /etc/kubernetes/pki/ mv /home/$\{USER\}/front-proxy-ca.crt /etc/kubernetes/pki/ mv /home/$\{USER\}/front-proxy-ca.key /etc/kubernetes/pki/ mv /home/$\{USER\}/etcd-ca.crt /etc/kubernetes/pki/etcd/ca.crt mv /home/$\{USER\}/etcd-ca.key /etc/kubernetes/pki/etcd/ca.key mv /home/$\{USER\}/admin.conf /etc/kubernetes/admin.conf

执行kubeadm join启动

kubeadm join 172.16.10.210:6443 --token r2tshb.svfb47rz7fdg874p --discovery-token-ca-cert-hash sha256:b2721cafb1e3979b19040aeebc544277998e15b683c93ee7360b28d363473c9a

其余节点重复上述操作。

node节点加入集群执行kubeadm join，如果出现报错想要初始化init执行kubeadm reset

\#部署Dashboard

git clone [https://github.com/bakuppus/kubernetes-dashboard.git][https_github.com_bakuppus_kubernetes-dashboard.git]

cd kubernetes-dashboard/

kubectl apply -f kubernetes-dashboard.yaml

\#\#让master也可以部署pod(默认master 禁用安装pod)

kubectl taint node master1 node-role.kubernetes.io/master-
