Usage of /usr/bin/gke-gcloud-auth-plugin:
      --account string                        Optional account to use for gcloud config command
      --add_dir_header                        If true, adds the file directory to the header of the log messages
      --alsologtostderr                       log to standard error as well as files (no effect when -logtostderr=true)
      --alsologtostderrthreshold severity     logs at or above this threshold go to stderr when -alsologtostderr=true (no effect when -logtostderr=true)
      --cluster string                        Name of the Cluster (only applicable when '--use_edge_cloud' is enabled).
      --impersonate_service_account string    Impersonate a service account to retrieve tokens for the Cluster.
      --legacy_stderr_threshold_behavior      If true, stderrthreshold is ignored when logtostderr=true (legacy behavior). If false, stderrthreshold is honored even when logtostderr=true
      --location string                       Location of the Cluster (only applicable when '--use_edge_cloud' is enabled).
      --log_backtrace_at traceLocation        when logging hits line file:N, emit a stack trace (default :0)
      --log_dir string                        If non-empty, write log files in this directory (no effect when -logtostderr=true)
      --log_file string                       If non-empty, use this log file (no effect when -logtostderr=true)
      --log_file_max_size uint                Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
      --logtostderr                           log to standard error instead of files (default true)
      --one_output                            If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
      --project string                        Parent project of the Cluster (mandatory when using --use_edge_cloud, optional otherwise).
      --skip_headers                          If true, avoid header prefixes in the log messages
      --skip_log_headers                      If true, avoid headers when opening log files (no effect when -logtostderr=true)
      --stderrthreshold severity              logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true unless -legacy_stderr_threshold_behavior=false)
      --use_application_default_credentials   Output is an ExecCredential filled with application default credentials.
      --use_edge_cloud                        Output is an ExecCredential for an Edge Cloud cluster.
  -v, --v Level                               number for the log level verbosity
      --version version[=true]                --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
      --vmodule moduleSpec                    comma-separated list of pattern=N settings for file-filtered logging
