Gafferctl

gafferctl can be used to run any command listed below. For example, you can get a list of all processes templates:

gafferctl is an HTTP client able to connect to a UNIX pipe or a tcp connection and connect to a gaffer node. It is using the httpclient module to do it.

You can create your own client either by using the client API provided in the httpclient module or by reading the doc here and passing your own message to the gaffer node. All messages are encoded in JSON.
