This command is meant to be used as a kustomize exec plugin.
|
|
|
|
The command reads the configuration file CONFIG passed as a first argument and
|
|
determines a particular plugin to execute. Additional arguments may be passed
|
|
to this command and can be used by the particular plugin.
|
|
|
|
CONFIG must be a structured kubernetes manifest (i.e. resource) and must have
|
|
'apiVersion' and 'kind' keys. If the appropriate plugin was not found, the
|
|
command returns an error.
