Usage: kubectl [OPTIONS] COMMAND [ARG...]

The following options can be passed to any command:
$ kubectl options -n, --namespace='': If present, the namespace scope for this CLI request. -s, --server='': The address and port of the Kubernetes API server. --cluster='': The name of the kubeconfig cluster to use. --context='': The name of the kubeconfig context to use. --kubeconfig='': Path to the kubeconfig file to use for CLI requests. --skip-headers=false: If true, avoid header prefixes in the log messages. --skip-log-headers=false: If true, avoid headers when opening log files. --add-dir-header=false: If true, adds the file directory to the header. --log-file='': If non-empty, use this log file. --log-dir='': If non-empty, write log files in this directory. --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. --alsologtostderr=false: log to standard error as well as files. --log-backtrace-at=:0: when logging hits line file:N, emit a stack trace. --stderrthreshold=2: logs at or above this threshold go to stderr. -v, --v=0: number for the log level verbosity --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. --user='': The name of the kubeconfig user to use. --username='': Username for basic authentication to the API server. --password='': Password for basic authentication to the API server. --as='': Username to impersonate for the operation. --as-group=[]: Group to impersonate for the operation, this flag can be repeated to specify multiple groups. --token='': Bearer token for authentication to the API server. --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. --insecure-skip-tls-verify=false: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure. --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. --cache-dir='/home/mtitek/.kube/http-cache': Default HTTP cache directory. --match-server-version=false: Require server version to match client version. --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. --vmodule=: comma-separated list of pattern=N settings for file-filtered logging.

explain Documentation of resources. get Display one or many resources. edit Edit a resource on the server. delete Delete resources by filenames, stdin, resources and names, or by resources and label selector.

rollout Manage the rollout of a resource. scale Set a new size for a Deployment, ReplicaSet or Replication Controller. autoscale Auto-scale a Deployment, ReplicaSet, or ReplicationController.

cluster-info Display cluster info. top Display Resource (CPU/Memory/Storage) usage. certificate Modify certificate resources. cordon Mark node as unschedulable. uncordon Mark node as schedulable. drain Drain node in preparation for maintenance. taint Update the taints on one or more nodes.
