操作系统	Ubuntu16.04 or CentOS7	选的是CentOS7	-
Kubernetes版本	v1.14.3	-	-
Docker版本	19.03.1	yum安装	-

组件服务TLS证书对应关系表

集群部署-自签TLS证书
组件	使用的证书	-
etcd	ca.pem, server.pem,server-key.pem	-
kube-apiserver	ca.pem, server.pem, server-key.pem	-
flanneld	ca.pem, server.pem, server-key.pem	-
kube-controller-manager	ca.pem, ca-key.pem	-
kubelet	ca.pem, ca-key.pem	-

服务器ip对应角色关系表

角色	IP	组件
k8s-master	192.168.10.21	kube-apiserver kube-controller-manager kube-scheduler docker
k8s-node01	192.168.10.22	etcd kubelet kube-proxy docker
k8s-node02	192.168.10.23	etcd kubelet kube-proxy docker
k8s-node02	192.168.10.23	etcd kubelet kube-proxy docker

2. Etcd数据库集群部署

2.1 修改主机别名，并配置互信

cat >> /etc/hosts  << EOF
192.168.10.21  k8s-master
192.168.10.22  k8s-node01
192.168.10.23  k8s-node02
192.168.10.24  k8s-node03
EOF

master节点为例：（其他节点参照即可）   
ssh-keygen
ssh-copy-id  k8s-node01

2.2 三个节点互相加一下规则

开启防火墙
systemctl    start   firewalld
firewall-cmd --permanent --add-rich-rule="rule family=ipv4 source address=192.168.10.21 accept"  
firewall-cmd --permanent --add-rich-rule="rule family=ipv4 source address=192.168.10.22 accept"  
firewall-cmd --permanent --add-rich-rule="rule family=ipv4 source address=192.168.10.23 accept"
firewall-cmd --permanent --add-rich-rule="rule family=ipv4 source address=192.168.10.24 accept" 
firewall-cmd --permanent --add-rich-rule="rule family=ipv4 source address=192.168.1.106 accept"

systemctl    daemon-reload
systemctl    restart firewalld

2.3 生成证书

拷贝k8s-master节点所需二进制包

#拷贝k8s-master节点所需二进制包
mkdir -p /app/kubernetes/{bin,cfg,ssl};
\cp  ./server/bin/{kube-apiserver,kube-scheduler,kube-controller-manager,kubectl} /app/kubernetes/bin;

#创建环境变量
echo "export PATH=$PATH:/app/kubernetes/bin" >> /etc/profile;
source /etc/profile;

#下载生成TLS证书的二进制工具
wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64;
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64;
wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64;
chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 cfssl-certinfo_linux-amd64;
mv cfssl_linux-amd64          /usr/local/bin/cfssl;
mv cfssljson_linux-amd64      /usr/local/bin/cfssljson;
mv cfssl-certinfo_linux-amd64 /usr/local/bin/cfssl-certinfo;

批量创建证书的执行配置脚本

\cp  *pem /app/kubernetes/ssl/

执行该证书脚本

sh  certificate.sh

其他node节点，k8s-node01、k8s-node02和k8s-node03创建目录

mkdir -p /app/kubernetes/{bin,cfg,ssl}

master节点上将TLS证书拷贝到node节点

for i in   1 2 3   ; do scp *pem  k8s-node0$i:/app/kubernetes/ssl/; done
//做了互信认证
//证书包含了master节点和node节点所需TLS证书

2.4 配置etcd

https://github.com/coreos/etcd/releases/tag/v3.3.12

所有节点，拷贝etcd二进制包

tar -xf etcd-v3.3.12-linux-amd64.tar.gz
for i in 1 2 3 ;do scp etcd-v3.3.12-linux-amd64/{etcd,etcdctl} k8s-node0$i:/app/kubernetes/bin/; done

执行配置脚本

cat etcd.sh 配置文件的脚本待确定

#!/bin/bash
#
#master节点部署etcd01节点名称和ip配置如下
k8s_node01=192.168.10.22
k8s_node02=192.168.10.23
k8s_node03=192.168.10.24

cat > /app/kubernetes/cfg/etcd << EOF 
KUBE_ETCD_OPTS="                                   \--name=etcd03                                      \--data-dir=/var/lib/etcd/default.etcd              \--listen-peer-urls=https://${k8s_node01}:2380      \--listen-client-urls=https://${k8s_node01}:2379,http://127.0.0.1:2379 \--advertise-client-urls=https://${k8s_node01}:2379                    \--initial-advertise-peer-urls=https://${k8s_node01}:2380              \--initial-cluster=‘etcd01=https://${k8s_node01}:2380,etcd02=https://${k8s_node01}:2380,etcd03=https://${k8s_node02}:2380‘ \--initial-cluster-token=etcd-cluster               \--initial-cluster-state=new                        \--cert-file=/app/kubernetes/ssl/server.pem         \--key-file=/app/kubernetes/ssl/server-key.pem      \--peer-cert-file=/app/kubernetes/ssl/server.pem    \--peer-key-file=/app/kubernetes/ssl/server-key.pem \--trusted-ca-file=/app/kubernetes/ssl/ca.pem       \--peer-trusted-ca-file=/app/kubernetes/ssl/ca.pem"
EOF

#配置etcd启动脚本服务

EOF

systemctl daemon-reload
systemctl start  etcd
systemctl enable etcd
systemctl status etcd

其他node节点，部署方法相同，只需修改etcd节点的名称和IP，执行脚本即可!

查看etcd集群状态

/app/kubernetes/bin/etcdctl --ca-file=/app/kubernetes/ssl/ca.pem         --cert-file=/app/kubernetes/ssl/server.pem                           --key-file=/app/kubernetes/ssl/server-key.pem                        --endpoints="https://192.168.10.22:2379,https:192.168.10.23:2379,https://192.168.10.24:2379" cluster-health

member 445a7d567d5cea7f is healthy: got healthy result from https://192.168.1.230:2379
member a04dd241344fb42a is healthy: got healthy result from https://192.168.1.240:2379
member e5160a05dd6cb2ed is healthy: got healthy result from https://192.168.1.226:2379
cluster is healthy

//出现cluster is healthy 说明集群状态是正常的

3. 部署所有节点docker服务

执行配置脚本安装docker服务

cat docker_install.sh

cat > docker_install.sh << EOF
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce

#安装docker tab键补全
yum install -y bash-completion
source /usr/share/bash-completion/completions/docker
source /usr/share/bash-completion/bash_completion

systemctl start  docker
systemctl enable docker
systemctl status docker
EOF

拷贝脚本到其他节点，执行安装,master可选择性安装不影响使用，安装后，能与node节点上的容器通信。

4. 部署flannel容器网络

https://github.com/coreos/flannel/releases/download/v0.11.0/flannel-v0.11.0-linux-amd64.tar.gz

master节点操作：

所有node节点上，拷贝flannel二进制包

tar xf flannel-v0.11.0-linux-amd64.tar.gz
for i in 1 2 3;do scp flanneld  mk-docker-opts.sh k8s-node0$i:/app/kubernetes/bin/;done

执行配置脚本

cat flanneld.sh

#!/bin/bash 
#
k8s_node01=192.168.10.22
k8s_node02=192.168.10.23
k8s_node03=192.168.10.24

#写入分配的子网段到etcd，供flanneld使用，需要先执行，方能启动flannel服务
/app/kubernetes/bin/etcdctl                       --ca-file=/app/kubernetes/ssl/ca.pem            --cert-file=/app/kubernetes/ssl/server.pem      --key-file=/app/kubernetes/ssl/server-key.pem   --endpoints="https://${k8s_node01}:2379,https://${k8s_node02}:2379,https://${k8s_node03}:2379"   set /coreos.com/network/config ‘{"Network": "172.50.0.0/16", "Backend": {"Type": "vxlan"}}‘

#配置Flannel：
cat > /app/kubernetes/cfg/flanneld << EOF 
flannel_options="                              \--etcd-endpoints=https://${k8s_node01}:2379,https://${k8s_node02}:2379,https://${k8s_node03}:2379 \-etcd-cafile=/app/kubernetes/ssl/ca.pem        \-etcd-certfile=/app/kubernetes/ssl/server.pem  \-etcd-keyfile=/app/kubernetes/ssl/server-key.pem"

获取创建的网络（验证用）

/app/kubernetes/bin/etcdctl                     --ca-file=/app/kubernetes/ssl/ca.pem           --cert-file=/app/kubernetes/ssl/server.pem     --key-file=/app/kubernetes/ssl/server-key.pem  --endpoints="https://192.168.10.22:2379,https://192.168.10.23:2379,https://192.168.10.24:2379"  get /coreos.com/network/config ‘{"Network": "172.50.0.0/16", "Backend": {"Type": "vxlan"}}‘

其他节点安装flanneld的方式相同。
测试不同节点互通，在当前节点访问另一个Node节点docker0 IP即可

注意事项：

1） 保证etcd通信，集群状态是正常的
2） 要先添加子网段，否则flannel启动报错
3） 要确保docker0与flannel.1在同一网段，若不在，需要重新加载启动下docker服务，默认的docker0网段的ip涉及到的环境变量，在/run/flannel/subnet.env
    这个文件里，是由第一步"写入子网段到etcd集群"中时，自动生成的，可修改。

5. 获取token文件

1）创建TLS Bootstrapping Token
2）创建kubelet kubeconfig
3）创建kube-proxy kubeconfig

在master节点上操作，然后将生成的配置文件拷贝到node节点上面

执行配置脚本

cat kubeconfig.sh

#!/bin/bash
#
# 创建 TLS Bootstrapping Token，token的字符可以随机的生成
export  BOOTSTRAP_TOKEN=$(head -c 16 /dev/urandom | od -An -t x | tr -d ‘ ‘)
cat > token.csv << EOF
${BOOTSTRAP_TOKEN},kubelet-bootstrap,10001,"system:kubelet-bootstrap"
EOF

# 创建kubelet bootstrapping kubeconfig 
KUBE_APISERVER="https://192.168.10.21:8080"

# 设置集群参数
kubectl config set-cluster kubernetes     --certificate-authority=/app/kubernetes/ssl/ca.pem      --embed-certs=true                    --server=${KUBE_APISERVER}            --kubeconfig=bootstrap.kubeconfig

# 设置客户端认证参数
kubectl config set-credentials kubelet-bootstrap     --token=${BOOTSTRAP_TOKEN}            --kubeconfig=bootstrap.kubeconfig

# 设置上下文参数
kubectl config set-context default        --cluster=kubernetes                  --user=kubelet-bootstrap              --kubeconfig=bootstrap.kubeconfig

# 设置默认上下文
kubectl config use-context default --kubeconfig=bootstrap.kubeconfig

#--------------------------------
# 创建kube-proxy kubeconfig文件

kubectl config set-cluster kubernetes   --certificate-authority=/app/kubernetes/ssl/ca.pem   --embed-certs=true                    --server=${KUBE_APISERVER}            --kubeconfig=kube-proxy.kubeconfig

kubectl config set-credentials kube-proxy   --client-certificate=./kube-proxy.pem     --client-key=./kube-proxy-key.pem         --embed-certs=true                        --kubeconfig=bootstrap.kubeconfig

kubectl config set-context default   --cluster=kubernetes               --user=kube-proxy                  --kubeconfig=kube-proxy.kubeconfig

kubectl config use-context default --kubeconfig=kube-proxy.kubeconfig

生成node节点所需配置文件以及token文件

chmod +x kubeconfig.sh  ; 
sh  kubeconfig.sh ;
//会生成 token.csv，bootstrap.kubeconfig，kube-proxy.kubeconfig，这三个文件，后面会用到

6. 部署Master节点组件

kubernetes master 节点包含的组件：

kube-apiserver

kube-scheduler

kube-controller-manager

目前这三个组件需要部署在同一台机器上

kube-scheduler、kube-controller-manager 和 kube-apiserver 三者的功能紧密相关；

同时只能有一个 kube-scheduler、kube-controller-manager 进程处于工作状态，如果运行多个，则需要通过选举产生一个 leader；

步骤简介：

拷贝二进制包启动服务命令；

拷贝token文件和需要的证书文件；

配置并执行"apiserver.sh 脚本；

验证kube-apiserver服务；

6.1 配置和启动 kube-apiserver 组件

二进制包包含客户端的所有组件

https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.12.md

执行配置脚本

cat apiserver.sh

#!/bin/bash
#

etcd-0               Healthy   {"health":"true"}   
etcd-2               Healthy   {"health":"true"}

6.2 配置和启动 kube-controller-manager 组件

执行配置脚本

7. 部署Node节点组件

Kubernetes node节点包含如下组件：

Flanneld：安装过程参考文档上面安装flannel网络。

kubelet：直接用二进制文件安装

kube-proxy：直接用二进制文件安装

步骤简介:

确认在之前我们安装配置的网络插件flannel已启动且运行正常

安装配置docker后启动

安装配置kubelet、kube-proxy后启动

验证

master节点操作：
拷贝node节点kubelet和kube-proxy服务所需配置文件

for i in 1 2 3 ; do scp bootstrap.kubeconfig kube-proxy.kubeconfig  k8s-node0$i:/app/kubernetes/cfg/; done
for i in 1 2 3 ; do scp ./server/bin/{kubelet,kube-proxy}           k8s-node0$i:/app/kubernetes/bin/; done  
证书一开始已经拷贝过去了

执行将kubelet-bootstrap用户绑定到系统集群角色

kubectl create clusterrolebinding kubelet-bootstrap   --clusterrole=system:node-bootstrapper              --user=kubelet-bootstrap

7.1 配置和启动 kubelet 组件

k8s-node01节点操作：

执行配置脚本

cat kubelet.sh

#!/bin/bash
#如下是node01为例
k8s_node01=192.168.10.22
k8s_node02=192.168.10.23
k8s_node03=192.168.10.24

其他k8s-node02节点部署方法相同，改下节点ip即可

附：其中/app/kubernetes/cfg/kubelet.config配置文件如下：

//无需手动配置，了解下即可。正常启动后，会自动加载进来，配置如下

cat /app/kubernetes/cfg/kubelet.config

apiVersion: v1
clusters:

通过 CSR 请求并验证

# kubectl certificate approve [NAME1,NAME2,NAME3]                 //可以同时给多个节点名进行授权认证
certificatesigningrequest "node-csr-Cm3XIZb_R6fEV1bbT9N2ufxuDAXkf05-8mnUjWbh6eo" approved

node-csr-bTrFC53MHuzspJQUlyYTsESLpQe4TlFnlUtmyiMASjY   92s   kubelet-bootstrap   Approved,Issued

7.2 配置和启动 kube-proxy 组件

k8s-node01节点操作：

执行配置脚本

cat kube-proxy.sh

#!/bin/bash
#如下是以node01为例
k8s_node01=192.168.10.22
k8s_node02=192.168.10.23
k8s_node03=192.168.10.24

#配置kube-proxy
cat > /app/kubernetes/cfg/kube-proxy << EOF
KUBE_PROXY_OPTS="                   \--logtostderr=true                  \--v=4                               \--hostname-override=${k8s_node01}   \--cluster-cidr=10.10.10.0/24        \--kubeconfig=/app/kubernetes/cfg/kube-proxy.kubeconfig"
EOF

#systemd管理kube-proxy组件
cat  > /usr/lib/systemd/system/kube-proxy.service << EOF 
[Unit]
Description=Kubernetes Proxy
After=network.target

[Service]
EnvironmentFile=-/app/kubernetes/cfg/kube-proxy
ExecStart=/app/kubernetes/bin/kube-proxy \$KUBE_PROXY_OPTS
Restart=on-failure

[Install]
WantedBy=multi-user.target  
EOF

systemctl daemon-reload
systemctl enable kube-proxy
systemctl start  kube-proxy
systemctl status kube-proxy

若kube-proxy服务有错误日志如下

Sep 20 09:35:16 k8s-node01 kube-proxy[25072]: E0920 09:35:16.077775   25072 reflector.go:126]
k8s.io/client-go/informers/factory.go:133: Failed to list *v1.Service: services is forbidden: User "system:anonymous
" cannot list resource "services" in API group "" at the cluster scope

解决方法：需要绑定一个cluster-admin的权限

否则映射的端口外网是访问不到的，权限不足

kubectl create clusterrolebinding system:anonymous   --clusterrole=cluster-admin   --user=system:anonymous

其他k8s-node02节点部署方式一样，修改下对应的节点ip即可

8. 查看k8s集群状态

# kubectl get node
NAME            STATUS   ROLES    AGE   VERSION
192.168.10.22   Ready    <none>   15s   v1.14.3
192.168.10.23   Ready    <none>   17s   v1.14.3
192.168.10.24   Ready    <none>   17s   v1.14.3

附：该STATUS 状态值由‘NotReady‘ --->  ‘Ready‘,说明集群节点添加成功

[root@k8s-master ~]# 
[root@k8s-master ~]# kubectl get cs
NAME                 STATUS    MESSAGE             ERROR
controller-manager   Healthy   ok                  
scheduler            Healthy   ok                  
etcd-1               Healthy   {"health":"true"}   
etcd-2               Healthy   {"health":"true"}   
etcd-0               Healthy   {"health":"true"}

9. 运行nginx测试容器

创建一个nginx web服务，测试集群是否正常

1）命令运行测试容器：
kubectl run nginx --image=nginx --replicas=3

2）启用yaml文件启动测试容器：
cat > nginx.yaml << EOF
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 3
  template:
    metadata:
      labels:
        run: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
EOF

运行容器：
kubectl   create   -f  nginx.yaml 

暴露映射外部端口，用来访问：
kubectl expose deployment nginx --port=88 --target-port=80 --type=NodePort

查看Pod，Service：

[root@k8s-master ~]# kubectl get pods
NAME                     READY   STATUS    RESTARTS   AGE
nginx-7db9fccd9b-5njsv   1/1     Running   0          45m
nginx-7db9fccd9b-tjz6z   1/1     Running   0          45m
nginx-7db9fccd9b-xtkdx   1/1     Running   0          45m
[root@k8s-master ~]# 
[root@k8s-master ~]# 
[root@k8s-master ~]# kubectl get svc
NAME         TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.10.10.1    <none>        443/TCP        47m
nginx        NodePort    10.10.10.73   <none>        88:49406/TCP   3m38s   
[root@k8s-master ~]#

访问node节点网址：

192.168.10.22:49406
192.168.10.23:49406
192.168.10.24:49406

访问结果如下：
[root@k8s-master ~]# curl -I  192.168.10.23:49406
HTTP/1.1 200 OK
Server: nginx/1.17.3

Last-Modified: Tue, 13 Aug 2019 08:50:00 GMT
Connection: keep-alive
ETag: "5d5279b8-264"
Accept-Ranges: bytes

附： 该代理端口在node节点上是可以查到的

10. 部署kubedns组件

管理节点配置并修改kube-dns.yaml文件

clusterIP与kubelet启动参数--cluster-dns一致即可，在service cidr中预选1个地址做dns地址

修改后配置

cat  > kube-dns.yaml <<  EOF

查看配置说明

kube-dns ServiceAccount不用修改，kubernetes集群预定义的ClusterRoleBinding system:kube-dns已将kube-system（系统服务一般部署在此）namespace中的
ServiceAccout kube-dns 与预定义的ClusterRole system:kube-dns绑定，而ClusterRole system:kube-dns具有访问kube-apiserver dns的api权限

查看重要信息

# kubectl get clusterrolebinding system:kube-dns -o yaml
………… 省略
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: system:kube-dns
subjects:

………… 省略
rules:
- apiGroups:
  - ""
  resources:
  - endpoints

启动kube-dns

kubectl create -f kube-dns.yaml

若kube-dns执行有误，想删掉重新安装

kubectl   get deployment --all-namespaces   //查看
kubectl   delete  -f  kube-dns.yaml         //清除

11. 验证Kubedns组件服务

kube-dns Deployment & Service & Pod

kube-dns Pod 3个容器已”Ready”，服务，deployment等也正常启动

kubectl get pod        -n kube-system -o wide
kubectl get service    -n kube-system -o wide
kubectl get deployment -n kube-system -o wide

kube-dns 查询

如下是查询dns是否成功解析的信息操作

默认的busybox镜像有问题，选用一个即可

# cat  > busybox.yaml  << EOF
apiVersion: v1
kind: Pod
metadata:
  name: busybox
  namespace: default
spec:
  containers:
  - name: busybox
    #image: zhangguanzhang/centos

    command:
      - sleep
      - "3600"
    imagePullPolicy: IfNotPresent
  restartPolicy: Always
EOF

运行带有工具的pod
# kubectl create  -f busybox.yaml

查看kube-dns的pod IP
# kubectl  get pod -n kube-system -o wide

$IP 为查出来的dns  pod 的 IP
注: 应该有输出信息的，如果没有输出，是其他问题    
# kubectl exec -ti busybox -- nslookup kubernetes.default

kube-dns，有三组日志

kubectl logs --namespace=kube-system $(kubectl get pods --namespace=kube-system -l k8s-app=kube-dns -o name | head -1) -c kubedns

kubectl logs --namespace=kube-system $(kubectl get pods --namespace=kube-system -l k8s-app=kube-dns -o name | head -1) -c dnsmasq

kubectl logs --namespace=kube-system $(kubectl get pods --namespace=kube-system -l k8s-app=kube-dns -o name | head -1) -c sidecar

12. 部署dashboard组件

管理节点执行

所用镜像名如下

netonline/kubernetes-dashboard-amd64:v1.8.3    //如下配置，以此为例
registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-amd64:v1.7.1

配置文件模板

# ConfigMap
wget https://raw.githubusercontent.com/kubernetes/kubernetes/master/cluster/addons/dashboard/dashboard-configmap.yaml

# Secret
wget https://raw.githubusercontent.com/kubernetes/kubernetes/master/cluster/addons/dashboard/dashboard-secret.yaml

# RBAC
wget https://raw.githubusercontent.com/kubernetes/kubernetes/master/cluster/addons/dashboard/dashboard-rbac.yaml

# dashboard-controller
wget https://raw.githubusercontent.com/kubernetes/kubernetes/master/cluster/addons/dashboard/dashboard-controller.yaml

# Service
wget https://raw.githubusercontent.com/kubernetes/kubernetes/master/cluster/addons/dashboard/dashboard-service.yaml

本实验使用yaml文件（修改版）

https://github.com/Netonline2016/kubernetes/tree/master/addons/dashboard

12.1 修改dashboard-configmap.yaml

暂不修改，针对此次验证，dashboard-controller也未使用到configmap

12.2 修改dashboard-rbac.yaml

默认dashboard-rbac.yaml定义了1个name为”kubernetes-dashboard-minimal”的Role；并做了name为”kubernetes-dashboard-minimal”的RoleBinding，向name为”kubernetes-dashboard”的ServiceAccount授权；

但默认的dashboard-rbac.yaml定义的Role权限太小，不太方便验证；

重新定义rbac，只需要定义新的ClusterRoleBinding: kubernetes-dashboard，将kubernetes自身的具有全部权限的ClusterRole: cluster-admin赋予ClusterRoleBinding；此授权方式在生产环境慎用；

修改后的配置

cat > dashboard-rbac.yaml << EOF
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding        ## 修改或新增部分
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    addonmanager.kubernetes.io/mode: Reconcile
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole             ## 修改或新增部分
  name: cluster-admin           ## 修改或新增部分
subjects:
  - kind: ServiceAccount
    name: kubernetes-dashboard  ## 修改或新增部分
namespace: kube-system
EOF

12.3 修改dashboard-secret.yaml

dashboard-secret.yaml不做修改

12.4 修改dashboard-controller.yaml

dashboard-controller.yaml定义了ServiceAccount资源（授权）与Deployment（服务Pod）

修改该文件使用的镜像

sed -i ‘s|k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3|netonline/kubernetes-dashboard-amd64:v1.8.3|g‘ dashboard-controller.yaml

修改后的配置文件

cat > dashboard-controller.yaml << EOF
apiVersion: v1

      serviceAccountName: kubernetes-dashboard
      tolerations:
      - key: "CriticalAddonsOnly"
        operator: "Exists"
EOF

12.5 修改dashboard-service.yaml

定义”NodePort” type，为验证通过控制节点直接访问dashboard（生产环境中建议不使用方式），”nodePort: 18443”定义具体的端口，不设置则在服务端口范围中随机产生

修改后的配置文件

cat  > dashboard-service.yaml << EOF 
apiVersion: v1
kind: Service
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
spec:
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort
  ports:
  - port: 443
    targetPort: 8443
    nodePort: 38443
EOF

12.6 启动kubernetes-dashboard并验证服务

启动rbac，secret，controller，service4个yaml文件定义的服务即可；

或者 kubectl create -f .

kubectl create -f dashboard-rbac.yaml 
kubectl create -f dashboard-secret.yaml 
kubectl create -f dashboard-controller.yaml 
kubectl create -f dashboard-service.yaml

查看相关服务

查看service，deployment,pod服务

# kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.10.10.2    <none>        53/UDP,53/TCP   23h
kubernetes-dashboard   NodePort    10.10.10.30   <none>        443:38443/TCP   92m

# kubectl get deployment -n kube-system

kubernetes-dashboard-8646f64494-6ttr4   1/1     Running   0          96m

获取集群服务列表
kubectl cluster-info

12.7 访问dashboard方式

查看nodePort，进行访问UI

# kubectl   get svc -n kube-system
NAME                   TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.10.10.2    <none>        53/UDP,53/TCP   23h
kubernetes-dashboard   NodePort    10.10.10.97   <none>        443:38443/TCP   22h

查看dashboard服务运行所在节点服务器

#  kubectl get pod -n kube-system -o wide
NAME                                  READY STATUS  RESTARTS AGE IP          NODE          NOMINATED NODE READINESS GATES
kube-dns-5995c87955-j5z7n             3/3   Running 6        26h 172.50.94.2 192.168.10.23 <none>         <none>
kubernetes-dashboard-8646f64494-5nzvs 1/1   Running 2        25h 172.50.29.2 192.168.10.24 <none>         <none>

访问UI地址

//谷歌和IE对证书有要求，访问异常，需要用火狐浏览器访问，并添加url例外

https://192.168.10.24:38443

创建管理员角色用户

创建了一个admin-user的服务账号，并放在kube-system命名空间下，并将cluster-admin角色绑定到admin-user账户，这样admin-user账户就有了管理员的权限。
默认情况下，kubeadm创建集群时已经创建了cluster-admin角色，我们直接绑定即可

# cat > dashboard-adminuser.yaml << EOF 
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kube-system
EOF

# kubectl create -f dashboard-adminuser.yaml

获取管理员的token值

# kubectl get secret -n kube-system  
NAME                               TYPE                                  DATA   AGE
