使用kubernetes client corev1api运行`CONNECT_GET_NAMESPACED_POD_EXEC`会发出错误请求

Question

按照这里的建议尝试了usings流-https://github.com/kubernetes-client/python/blob/master/examples/exec.py

冉：

api_response = stream(core_v1_api.connect_get_namespaced_pod_exec,
                      name, namespace,
                      command=exec_command,
                      stderr=True, stdin=False,
                      stdout=True, tty=False)

得到此错误：

core_v1_api = client.CoreV1Api()
api_response = core_v1_api.connect_get_namespaced_pod_exec(name=name,namespace=namespace,command=exec_command,stderr=True, stdin=False,stdout=True, tty=False)

Answer 1

我写了一个简单的程序来检查：

from kubernetes import client, config
from kubernetes.stream import stream

# create an instance of the API class

config.load_kube_config()
api_instance = client.CoreV1Api()

exec_command = [
    '/bin/sh',
    '-c',
    'echo This is Prafull Ladha and it is test function']
resp = stream(api_instance.connect_get_namespaced_pod_exec, "nginx-deployment-76bf4969df-467z2", 'default',
              command=exec_command,
              stderr=True, stdin=False,
              stdout=True, tty=False)
print("Response: " + resp)

它对我来说非常有效。

我相信您使用minikube进行开发。它无法识别您的主机名。您可以通过在程序中禁用assert_hostname使其工作，例如：

from kubernetes.client import configuration 
config.load_kube_config()                                                 
configuration.assert_hostname = False
