Krustlet bootstrap bash script on minikube

I was attempting to run a hello-world demo of Krustlet on minikube. According to Krustlet's official tutorial, there is step to generate a bootstrap config with a utility script.

Since I was running minikube without kubectl manually installed, I had to use minikube kubectl rather than kubectl. So I also did this replacement in the script and tried to run it with bash bootstrap.sh. However, the result was a complaint:

Error: unknown shorthand flag: 'f' in -f
See 'minikube kubectl --help' for usage.

Please, any help?

First look at the bash minikube kubectl --help page:

      --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
  -b, --bootstrapper string              The name of the cluster bootstrapper that will set up the Kubernetes cluster. (default "kubeadm")
  -h, --help                             
      --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
      --log_file string                  If non-empty, use this log file
      --log_file_max_size uint           Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
      --logtostderr                      log to standard error instead of files
      --one_output                       If true, only write logs to their native severity level (vs also writing to each lower severity level)
  -p, --profile string                   The name of the minikube VM being used. This can be set to allow having multiple instances of minikube independently. (default "minikube")
      --skip_headers                     If true, avoid header prefixes in the log messages
      --skip_log_headers                 If true, avoid headers when opening log files
      --stderrthreshold severity         logs at or above this threshold go to stderr (default 2)
      --user string                      Specifies the user executing the operation. Useful for auditing operations executed by 3rd party tools. Defaults to the operating system username.
  -v, --v Level                          number for the log level verbosity
      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging

This is a very simple command and does not support the -f flag. To solve this problem you can install full kubectl command. You can find the guide also here. Of course you can also setup your cluster not in Minikube. Basically, you need to have kubectl command to run your script.
