kubectl config set: please add some examples

[ahmetb]

kubectl v1.10
/kind documentation
/sig cli

This command's --help message is not useful at all. Can we please have some commonly used tasks listed in EXAMPLES section of the --help message?

$ kubectl config set --help
Sets an individual value in a kubeconfig file

PROPERTY _NAME is a dot delimited name where each token represents either an attribute name or a map key.  Map keys may
not contain dots.

PROPERTY _VALUE is the new value you wish to set. Binary fields such as 'certificate-authority-data' expect a base64
encoded string unless the --set-raw-bytes flag is used.

Options:
      --set-raw-bytes=false: When writing a []byte PROPERTY_VALUE, write the given string directly without base64
decoding.

Usage:
  kubectl config set PROPERTY_NAME PROPERTY_VALUE [options]

Use "kubectl options" for a list of global command-line options (applies to all commands).

It would also be nice if there was an option to kubectl config view that would show the property names in a format that was compatible with config set.

+1 agree that examples would be very helpful.

I do have one example that will work, but I have not determined the total syntax for "maps"

 kubectl config set clusters.cluster.certificate-authority-data $(echo "cert_data_here" | base64 -i -)
