摘抄这个，因为这个有些不全 导致走了一些弯路

一、配置镜像源

国外特别的慢

{"debug": true,"experimental": false,"insecure-registries": ["try-registry.example.com"],"registry-mirrors": ["https://mirror.ccs.tencentyun.com","https://reg-mirror.qiniu.com","https://docker.mirrors.ustc.edu.cn","https://dockerhub.azk8s.cn","https://hub-mirror.c.163.com","https://registry.docker-cn.com"]
}

二、使用步骤

1.引入库

代码如下（示例）：

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import warnings
warnings.filterwarnings('ignore')
import  ssl
ssl._create_default_https_context = ssl._create_unverified_context

2.安装k8s

勾选并点击restart

等一段时间，呈现上面的样子。在列表中会有很多k8s的pod

3.加载资源

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

注意 :有时连接不到raw.githubusercontent.com

1. 查找IP

   https://site.ip138.com/raw.githubusercontent.com/
   

   

2. 配置hosts，在末尾加一行 中间有空格

   C:\Windows\System32\drivers\etc
   

   

4.K8S官方dashboard

1. 随便找个地方创建dashbord.yml

C:\Users\LENOVO\Desktop\dashbord.yml

2. 执行命令，即可创建Dashbord相关POD。如果报命名空间不存在，可以创建对应的命名空间，再次执行上面的代码。

kubectl apply -f xxx.yaml

3. 启动

kubectl proxy

4. 访问网址

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/login

5. 创建用户
地址

C:\Users\LENOVO\Desktop\dash.yaml

增加内容

apiVersion: v1
kind: ServiceAccount
metadata:name: admin-usernamespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:name: admin-user
roleRef:apiGroup: rbac.authorization.k8s.iokind: ClusterRolename: cluster-admin
subjects:
- kind: ServiceAccountname: admin-usernamespace: kubernetes-dashboard

6. 加载资源

kubectl apply -f dash.yaml

7. 查看用户

kubectl -n kubernetes-dashboard get sa

8. 给用户生成token

kubectl create token -n kubernetes-dashboard admin-user

9. 将生成的token 放入web中
   

总结

java调用k8s的api就是使用这个token，并且token很容易就过期。需要重新创建。刚刚摸索完  不对指正。
