1、Kubernetes API使用
1.1 API是什么？
API（Application Programming Interface，应用程序接口）： 是一些预先定义的接口（如函数、HTTP接口），或指软件系统不同组成部分衔接的约定。 用来提供应用程序与开发人员基于某软件或硬件得以访问的一组例程，而又无需访问源码，或理解内部工作机制的细节。
K8s也提供API接口，提供这个接口的是管理节点的apiserver组件，apiserver服务负责提供HTTP API，以便用户、其他组件相互通信。
有两种方式可以操作K8s中的资源：
- HTTP API：https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.19/
- 客户端库： https://kubernetes.io/zh/docs/reference/using-api/client-libraries/
1.2 K8s认证方式
K8s支持三种客户端身份认证：
- HTTPS 证书认证：基于CA证书签名的数字证书认证（kubeconfig文件）
实际上官方使用kubeconfig 文件，也是用的里面的token，这个方式不建议，因为带了根证书。自己开发跳过这块逻辑，所以可以用这个文件登录了。
- HTTP Token认证：通过一个Token来识别用户（ServiceAccount）
- HTTP Base认证：用户名+密码的方式认证（1.19+已经弃用）
安装Kubernetes客户端库：
pip install kubernetes -i https://pypi.tuna.tsinghua.edu.cn/simple
HTTPS证书认证（kubeconfig）：
# 默认使用： cat ./kube/config
from kubernetes import client, config
import os
kubeconfig = os.path.join(os.getcwd(),"kubeconfig") # 获取当前目录并拼接文件
config.load_kube_config(kubeconfig) # 指定kubeconfig配置文件（/root/.kube/config）
apps_api = client.AppsV1Api() # 资源接口类实例化
#通过 kubectl api-resources | grep deploy 判断是哪个资源接口
for dp in apps_api.list_deployment_for_all_namespaces().items:
print(dp) # 打印Deployment对象详细信息
证书认证太麻烦，还需要我复制文件内容，这里我选择token认证比较方便，只需要创建一次即可。
HTTP Token认证（ServiceAccount）：
获取Token字符串：创建service account并绑定默认cluster-admin管理员集群角色：
# 创建用户
kubectl create serviceaccount k8s-api-admin -n kube-system
# 用户授权
kubectl create clusterrolebinding k8s-api-admin --clusterrole=cluster-admin --serviceaccount=kube-system:k8s-api-admin
# 获取用户Token
#1）先查看secret
kubectl -n kube-system get secret
#2）再查看具体token
kubectl describe secrets -n kube-system k8s-api-admin-token-rwb69
这步如果没有做就会报错
Message: Forbidden!Configured service account doesn't have access. Service account may have been revoked. endpoints "xxx" is forbidden: User "system:serviceaccount:xxx:default" cannot get resource "endpoints" in API group "" in the namespace "xxx".Pod内部环境应用程序在访问Kubernetes的Api Server的时候的权限验证就是通过serviceaccount实现的。
当你创建namespace的时候，会默认为该namespace创建一个名为default的serviceaccount。可以通过命令查看:
kubectl get sa -n 你的namespace
正如报错所示“system:serviceaccount:xxx:default”，这个就是pod内部的用到的默认的serviceaccount，xxx代表你的namespace，default则是namespace的默认serviceaccount名字，前面system:serviceaccount代表k8s中的serviceaccount用户组。
所以这个的错误的信息代表的意思是，pod用namespace默认的serviceaccout是没有权限访问K8s的 API group的。
全部代码，基于Python3实现
