This will make your HTTPS connections insecure--kubeconfig stringPath to the kubeconfig file to use for CLI requests.--kuberc stringPath to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.--match-server-versionRequire server version to match client version-n, --namespace stringIf present, the namespace scope for this CLI request--password stringPassword for basic authentication to the API server--profile string Default: "none"Name of profile to capture.
