Kubernetes客户端python API错误401-未经授权

编程问答 2022-06-12

问题描述

我正在尝试创建一个Python客户端以在AKS集群上的Pod中连接并执行命令，但是当尝试连接时，我从客户端401 Unauthorized处收到消息错误。有人在API中遇到此问题吗？

API例外消息： 

kubernetes.client.rest.ApiException: (401)
Reason: Unauthorized
HTTP response headers: HTTPHeaderDict({'Audit-Id': 'ba23c2b3-d65b-4200-b802-161300119860','Cache-Control': 'no-cache,private','Content-Type': 'application/json','Date': 'Mon,21 Sep 2020 18:21:59 GMT','Content-Length': '129'})
HTTP response body: {"kind":"Status","apiVersion":"v1","Metadata":{},"status":"Failure","message":"Unauthorized","reason":"Unauthorized","code":401}

Python客户端API Kubernetes 

    from __future__ import print_function
import time
import kubernetes.client
import os
from kubernetes.stream import stream
from kubernetes.client.rest import ApiException
from pprint import pprint


name = input("Insira o POD name cadasTrado")
namespace = input("namespace do POD cadasTrado")
NomeAtuador = input("Insira o nome do atuador a ser gerado o arquivo de configuração")


configuration = kubernetes.client.Configuration()
#configuration.verify_ssl=False
#configuration.assert_hostname = False
configuration.api_key_prefix['authorization'] = 'Bearer'
configuration.api_key['authorization'] = 'MYTOKEN'
configuration.ssl_ca_cert= 'PATH TO CA.CRT'
configuration.host = "HOST_IP:443"

api_instance = kubernetes.client.CoreV1Api(
    kubernetes.client.apiclient(configuration))


exec_command = [
            '/etc/openvpn/setup/newClientCert.sh',(NomeAtuador),'xxxxxxx']

resp = stream(api_instance.connect_post_namespaced_pod_exec(
    (name),(namespace),command=exec_command,stderr=True,stdin=True,stdout=True,tty=True))
print("Response: " + resp)

我正在使用 Python 3.8.2 和 Kubernetes 1.16.13

解决方法

要解决我的问题，我将以下配置添加到群集配置中。

kubectl create clusterrolebinding serviceaccounts-cluster-admin \   --clusterrole=cluster-admin \   --group=system:serviceaccounts
