`source`

source reads resources from a local directory and writes them in Function Specification wire format to stdout. The output of the source can be pipe’d to commands such as kpt fn eval that accepts Function Specification wire format. source is useful for chaining functions using Unix pipe. For more details, refer to Chaining functions.

Synopsis #

kpt fn source [DIR] [flags]

Args #

DIR:
  Path to the local directory containing resources. Defaults to the current
  working directory.

Flags #

--fn-config:
  Path to the file containing `functionConfig`.

--include-meta-resources:

  resources are included by default with kpt version v1.0.0-beta.15+.

--output, o:
  If specified, the output resources are written to stdout in provided format.
  Allowed values:
  1. stdout(default): output resources are wrapped in ResourceList and written to stdout.
  2. unwrap: output resources are written to stdout, in multi-object yaml format.

# output to DIR directory.
