python调用kubernetesAPI简单使用方法

pip install kubernetes -i https://pypi.douban.com/simple

import os
from kubernetes import client, config
config.load_kube_config(file_path)  # 指定kubeconfig配置文件
apps_api = client.AppsV1Api()  # 资源接口类实例化

for dp in apps_api.list_deployment_for_all_namespaces().items:
    print(dp)

configuration.verify_ssl = True   # 启用证书验证
configuration.api_key = {"authorization": "Bearer " + token}  # 指定Token字符串
client.Configuration.set_default(configuration)
