`sink`

sink reads resources from stdin and writes them to a local directory. Resources must be in one of the following input formats:

1. Multi object YAML where resources are separated by ---.

2. KRM Function Specification wire format where resources are wrapped in an object of kind ResourceList.

sink is useful for chaining functions using Unix pipe. For more details, refer to Chaining functions.
