一，简单搭建，未使用ssl证书，可载谷歌浏览器访问
1，拉取镜像
docker pull gcrxio/kubernetes-dashboard-amd64:v1.10.1
docker tag gcrxio/kubernetes-dashboard-amd64:v1.10.1 k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.1
# 为主节点打标签，使容器起在主节点，修改部署文件见第2步
kubectl label node k8s-master type=master
2，k8s dashboard 部署yaml
cat kubernetes-dashboard.yaml

部署：
kubectl apply -f kubernetes-dashboard.yaml
查看：
kubectl get pods --all-namespaces
使用API Server 访问
https://<master-ip>:<apiserver-port>/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
访问结果为：
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "services "https:kubernetes-dashboard:" is forbidden: User "system:anonymous" cannot get services/proxy in the namespace "kube-system"",
"reason": "Forbidden",
"details": {
"name": "https:kubernetes-dashboard:",
"kind": "services"
},
"code": 403
}
这是因为没有进行认证，需要去创建一个证书
创建证书
#将kubectl的配置文件复制到$HOME/.kube/config中,$HOME/.kube/config 可能存在，可以先备份
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
生成p12文件
# 生成client-certificate-data
grep 'client-certificate-data' ~/.kube/config | head -n 1 | awk '{print $2}' | base64 -d >> kubecfg.crt
# 生成client-key-data
grep 'client-key-data' ~/.kube/config | head -n 1 | awk '{print $2}' | base64 -d >> kubecfg.key
# 生成p12，这里会要求输入密码，记住这个密码
openssl pkcs12 -export -clcerts -inkey kubecfg.key -in kubecfg.crt -out kubecfg.p12 -name "kubernetes-client"
导入p12文件；可以在谷歌浏览器内导入私有证书
装过程中需要输入的密码则为生成p12文件过程中输入的密码
安装完成后，关闭所有的浏览器，再重新打开，就会显示让选择证书的界面，选择证书，就会出现登录界面。
创建用户
vi admin-user.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kube-system
kubectl create -f admin-user.yaml
用户绑定角色
vi admin-user-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1beta1
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
kubectl create -f admin-user-role-binding.yaml
获取token ,这个token 是系统默认的token
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
访问
https://172.20.7.132:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy
输入获取的token

问题：
1，搭建使用了系统默认的证书，并未自己新建证书进行加载
2，对角色，用户绑定等知识点不熟
3，集成Heapster插件安装失败
4，细节不懂，只是照抄而已
