# 使用kubectl options可以看到添加哪些选项。 root@k8s-master01:~# kubectl options The following options can be passed to any command:
--add-dir-header=false: If true, adds the file directory to the header of the log messages --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='/root/.kube/cache': Default 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-file='': If non-empty, use this log file --log-file-max-size=1800: Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. --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 --one-output=false: If true, only write logs to their native severity level (vs also writing to each lower severity level) --password='': Password for basic authentication to the API server --profile='none': Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex) --profile-output='profile.pprof': Name of the file to write the profile to --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 --skip-headers=false: If true, avoid header prefixes in the log messages --skip-log-headers=false: If true, avoid headers when opening log files --stderrthreshold=2: logs at or above this threshold go to stderr --tls-server-name='': Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used --token='': Bearer token for authentication to the API server --user='': The name of the kubeconfig user to use --username='': Username for basic authentication to the API server -v, --v=0: number for the log level verbosity --vmodule=: comma-separated list of pattern=N settings for file-filtered logging --warnings-as-errors=false: Treat warnings received from the server as errors and exit with a non-zero exit code
root@k8s-master01:~# kubectl config --help Modify kubeconfig files using subcommands like "kubectl config set current-context my-context"
The loading order follows these rules:
1. If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes place. 2. If $KUBECONFIG environment variable is set, then it is used as a list of paths (normal path delimiting rules for your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list. 3. Otherwise, ${HOME}/.kube/config is used and no merging takes place.
Available Commands: current-context Displays the current-context delete-cluster Delete the specified cluster from the kubeconfig delete-context Delete the specified context from the kubeconfig delete-user Delete the specified user from the kubeconfig get-clusters Display clusters defined in the kubeconfig get-contexts Describe one or many contexts get-users Display users defined in the kubeconfig rename-context Renames a context from the kubeconfig file. set Sets an individual value in a kubeconfig file set-cluster Sets a cluster entry in kubeconfig set-context Sets a context entry in kubeconfig set-credentials Sets a user entry in kubeconfig unset Unsets an individual value in a kubeconfig file use-context Sets the current-context in a kubeconfig file view Display merged kubeconfig settings or a specified kubeconfig file
