Kubectl连接到Azure ACS群集

Question

我已成功将群集部署到Azure。 现在尝试设置kubectl来使用它。

正在运行：

az acs kubernetes get-credentials --resource-group=group --name=cluster

结果是：

scp: .kube/config: No such file or directory
Traceback (most recent call last):
  File "/Users/me/lib/azure-cli/lib/python2.7/site-packages/azure/cli/main.py", line 36, in main
    cmd_result = APPLICATION.execute(args)
  File "/Users/me/lib/azure-cli/lib/python2.7/site-packages/azure/cli/core/application.py", line 212, in execute
    result = expanded_arg.func(params)

    return self.handler(*args, **kwargs)

    reraise(*sys.exc_info())

    raise SCPException(asunicode(msg[1:]))
SCPException: scp: .kube/config: No such file or directory

文件~/.kube/config存在，并且我可以ssh到集群的主节点。

知道我正在做什么会出错吗？

更新。

尝试按以下任一注释运行命令：

az acs kubernetes get-credentials --resource-group=group --name=cluster -f /Users/me/.kube/config --debug

并收到以下信息：

azure cli的版本是2.0.18。 不胜感激建议。

Answer 1

尝试使用--file -f标志指定.kube目录中“ config”文件的绝对路径，您可以使用--debug进行进一步调试。

az acs kubernetes get-credentials --resource-group=group --name=cluster -f /.../.../.kube/config --debug

Answer 2

就我而言，.kube / config文件不是在主服务器上创建的。 尝试创建.kube / config文件时发生错误，我通过ssh-ing到主节点并查看/ var / log / azure目录注意到了这一错误。 错误与我的服务主体密码有关。 有了新的服务主体，新群集就可以正常工作。
