安装最新版本的kubernets（+安装插件dashboard）

一、安装docker
// 安装系统工具:
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
// 添加docker yum repo信息:
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
// 更新并安装 docker:
sudo yum makecache fast
sudo yum -y install docker-ce
// 开启docker服务并设置开机启动:
sudo systemctl start docker
sudo systemctl enable docker
// 设置docker:
sudo mkdir -p /etc/docker
cat /etc/docker/daemon.json
{
  "exec-opts": ["native.cgroupdriver=systemd"],　　##这一步一定要有，否则在初始化kubectl的时候很可能会报错
  "bip": "10.20.0.1/16",
  "fixed-cidr": "10.20.0.0/16",
  "mtu": 1500,
  "insecure-registries": ["harbor.eainc.com"]
}
// 重启 docker
sudo systemctl daemon-reload
sudo systemctl restart docker
// 关闭swap，否则会导致kubectl服务启动失败sudo swapoff -a    
二、安装kubelet、kubeadm、kubectl
// 设置kubernetes软件源
cat /etc/yum.repos.d/kubrenetes.repo
 [kubernetes]
 name=Kubernetes Repo
 baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
 gpgcheck=0
 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
// 安装 kubelet kubeadm kubectl 服务yum install -y kubelet kubeadm kubectl

// 查看kubectl（很重要）# kubectl version Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.0", GitCommit:"e8462b5b5dc2584fdcd18e6bcfe9f1e4d970a529", GitTreeState:"clean", BuildDate:"2019-06-19T16:40:16Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"}

// kubectl 的版本是 1.15.0 ，后面docker拉取的kube- 服务也要为1.15.0

三、安装基础镜像
docker pull mirrorgooglecontainers/kube-apiserver:v1.15.0
docker pull mirrorgooglecontainers/kube-controller-manager:v1.15.0
docker pull mirrorgooglecontainers/kube-scheduler:v1.15.0
docker pull mirrorgooglecontainers/kube-proxy:v1.15.0
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd:3.3.10
docker pull coredns/coredns:1.3.1
docker pull docker.io/dockerofwj/flannel

docker tag mirrorgooglecontainers/kube-apiserver:v1.15.0 k8s.gcr.io/kube-apiserver:v1.15.0
docker tag mirrorgooglecontainers/kube-controller-manager:v1.15.0 k8s.gcr.io/kube-controller-manager:v1.15.0
docker tag mirrorgooglecontainers/kube-scheduler:v1.15.0 k8s.gcr.io/kube-scheduler:v1.15.0
docker tag mirrorgooglecontainers/kube-proxy:v1.15.0 k8s.gcr.io/kube-proxy:v1.15.0
docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag mirrorgooglecontainers/etcd:3.3.10 k8s.gcr.io/etcd:3.3.10
docker tag coredns/coredns:1.3.1 k8s.gcr.io/coredns:1.3.1
docker tag docker.io/dockerofwj/flannel quay.io/coreos/flannel:v0.10.0-amd64

docker image rm mirrorgooglecontainers/kube-apiserver:v1.15.0
docker image rm mirrorgooglecontainers/kube-controller-manager:v1.15.0
docker image rm mirrorgooglecontainers/kube-scheduler:v1.15.0
docker image rm mirrorgooglecontainers/kube-proxy:v1.15.0
docker image rm mirrorgooglecontainers/pause:3.1
docker image rm mirrorgooglecontainers/etcd:3.3.10
docker image rm coredns/coredns:1.3.1
docker image rm docker.io/dockerofwj/flannel
四、k8s初始化
# kubeadm init --kubernetes-version=v1.15.0 --apiserver-advertise-address=192.168.37.49 --pod-network-cidr=10.10.0.0/16 --ignore-preflight-errors=swap　　  ............................
　Your Kubernetes control-plane has initialized successfully!　　### 看到这一行说明初始化成功

To start using your cluster, you need to run the following as a regular user:

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

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.3.4:6443 --token 21k4ls.cdne6rd3p8p31gpy     --discovery-token-ca-cert-hash sha256:dc5a8012c92dae38cedb7581153552d7f8b589bf670b67cb131da144eff83124### 最后两行很重要，关系到node节点的设置


// 设置环境变量


mkdir -p $HOME/.kube


sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config


sudo chown $(id -u):$(id -g) $HOME/.kube/config


// 配置 kubectl并验证


echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> /etc/profile


source /etc/profile


echo $KUBECONFIG #查看是否输出正确内容


// 设置系统参数


sysctl net.bridge.bridge-nf-call-iptables=1


 


五、Master安装Pod网络


// Pod网络用于Pod之间进行通信。这里我们选用flannel网络方案



vim kube-flannel.yaml
#添加以下内容

wget https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

// 修改配置文件
# sed -i ‘s/k8s.gcr.io/loveone/g‘ kubernetes-dashboard.yaml
# sed -i ‘/targetPort:/a\ \ \ \ \ \ nodePort: 30001\n\ \ type: NodePort‘ kubernetes-dashboard.yaml

// 部署dashboard
# kubectl create -f kubernetes-dashboard.yaml

// 启动相关服务
kubectl get deployment kubernetes-dashboard -n kube-system
kubectl get pods -n kube-system -o wide
kubectl get services -n kube-system

// 查看端口是否启动
netstat -ntlp|grep 30001

七、浏览器测试
由于https证书的问题，暂时只能先通过火狐浏览器增加安全例外的方式访问（亲测，google浏览器不行）

在Firefox浏览器输入Dashboard访问地址：https://192.168.3.4:30001




令牌获取方法如下：令牌是token后面的内容



# kubectl create serviceaccount  dashboard-admin -n kube-system
serviceaccount/dashboard-admin created

# kubectl create clusterrolebinding  dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created

# kubectl describe secrets -n kube-system $(kubectl -n kube-system get secret | awk ‘/dashboard-admin/{print $1}‘)
