一直在尝试让 kubernetes 的 python 客户端按预期工作。祝你好运config.load_kube_config()现在我想从远程机器使用Python客户端，而远程机器都没有kubectl nor ~/.kube/config在上面。尝试了 python 客户端 API 参考，例如this https://github.com/kubernetes-client/python/blob/master/kubernetes/docs/CoreV1Api.md#list_pod_for_all_namespaces
Snippet:
from __future__ import print_function
import time
import kubernetes.client
from kubernetes.client.rest import ApiException
from pprint import pprint
# Configure API key authorization: BearerToken
configuration = kubernetes.client.Configuration()
configuration.api_key['authorization'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['authorization'] = 'Bearer'
起初，我似乎需要使用默认的服务帐户令牌，其中显示：
configuration.api_key['authorization'] = 'YOUR_API_KEY
看了很多之后很快就发现事实并非如此[SSL: CERTIFICATE_VERIFY_FAILED]
有人可以提示我可以从新安装中获得这个吗？
使用 kubeadm 启动该集群。
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T21:10:44Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T09:42:01Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}
设法使用以下方法从 master 获取令牌：
$ kubectl describe secret $(kubectl get secrets | grep default | cut -f1 -d ' ') | grep -E '^token' | cut -f2 -d':' | tr -d '\t'
上面的结果被命名为ApiToken在下面的Python代码片段中。
from kubernetes import client, config
from kubernetes.client.rest import ApiException
ApiToken = 'eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJkZWZhdWx0Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZWNyZXQubmFtZSI6ImRlZmF1bHQtdG9rZW4tbXF0eG4iLCJrdWJlcm5ldGVzLmlvL3NlcnZpY2VhY2NvdW50L3NlcnZpY2UtYWNjb3VudC5uYW1lIjoiZGVmYXVsdCIsImt1YmVybmV0ZXMuaW8vc2VydmljZWFjY291bnQvc2VydmljZS1hY2NvdW50LnVpZCI6IjA5NWQ3ZGVhLTA5MDgtMTFlOC04NTFiLTA4MDAyNzk0OGE2OSIsInN1YiI6InN5c3RlbTpzZXJ2aWNlYWNjb3VudDpkZWZhdWx0OmRlZmF1bHQifQ.DBk6gyh4BFy-Gc94dihasYXLbspMvMEjuzFS-AEyNUwk6pR1zsdYOqxo5J-0t6qHN09JyyNK5Oz75cR6bYOGxir1a7SveQpXly4S2Iu3K3o6n8ys_kdP4lNMgBZy--rE0h4neG9s91ven36XP4nYZMwvWal56w39nCUmkomR2-DfhaD4-_Mqq2bd7lmETNinD2hpzTa9cf46VTTY0kcIwhk8FzxEtPA3kxoZul0AfpZT2QlyzLk9fTBRPjd57XbktBgQmiO2wppa_A1KN1Kg83fk1p40hSfY4Vf7Dr76rmKgAUVae-qkN725FWj-4NqzktjyAqalli5jcHo2leJv0A'

响应是HTTP/1.1 403 Forbidden信息。

现在解决这个阶段的问题。
