如何控制kubectl与哪个集群对话？
如何控制kubectl与哪个集群对话？
提问于 2019-06-13 03:37:45
我正在使用kubectl来控制本地microk8s安装。我配置了一个本地Google cloud shell连接，以避免通过GKE仪表板提供的可笑机器。
kubectl可以引用不同环境的可能性是一个可怕的想法，显然是基于kubectl命令行界面的概念，它没有提供指定远程集群的方法。

kubectl config use-context命令可以用来修改kubectl与之交谈的对象。
使用配置文件配置对多个群集的访问权限。在一个或多个配置文件中定义群集、用户和上下文后，可以使用在群集之间快速切换。configure-access-multiple-clusters/

您可以向kubectl命令提供/添加--context和--namespace选项，以对任何群集运行kubectl。如果您同时使用多个集群来回工作，这将非常方便。
kubectl --cluster=my_cluster --namespace=my_namespace get pods注意:请为您的环境更改群集和命名空间名称。
下面是更多的kubectl选项：
~/git/kubernetes (master) $ kubectl options
The following options can be passed to any command:
--alsologtostderr=false: log to standard error as well as files
--as='': Username to impersonate for the operation
--as-group=[]: Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--cache-dir='/Users/robertrt/.kube/http-cache': Default HTTP cache directory
--certificate-authority='': Path to a cert file for the certificate authority
--client-certificate='': Path to a client certificate file for TLS
--client-key='': Path to a client key file for TLS
--cluster='': The name of the kubeconfig cluster to use
--context='': The name of the kubeconfig context to use
--insecure-skip-tls-verify=false: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
--kubeconfig='': Path to the kubeconfig file to use for CLI requests.
--log-backtrace-at=:0: when logging hits line file:N, emit a stack trace
--log-dir='': If non-empty, write log files in this directory
--log-flush-frequency=5s: Maximum number of seconds between log flushes
--logtostderr=true: log to standard error instead of files
--match-server-version=false: Require server version to match client version
-n, --namespace='': If present, the namespace scope for this CLI request
--request-timeout='0': The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
-s, --server='': The address and port of the Kubernetes API server
--stderrthreshold=2: logs at or above this threshold go to stderr
--token='': Bearer token for authentication to the API server
--user='': The name of the kubeconfig user to use
-v, --v=0: log level for V logs
--vmodule=: comma-separated list of pattern=N settings for file-filtered logging页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
