kubectl is the kubernetes swiss army knife - as well as being able to manipulate kubernetes it gives access to loads of data
But to make use of that data we need to format it - and one of the more powerful ways of doing this is using gotemplates
the help page just says
–template=’':
Template string or path to template file to use when -o=go-template, -o=go-template-file.
The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].

It hasn’t been especially clear to me how a new token is best generated.
