Function Controller

Purpose

The function controller runs inside kubernetes and continuously monitors the function and topic custom resource definitions for changes. It then reacts by requesting the deployment of functions, and scales them according to new events being detected on their input topics.

Development

Prerequisites

The following tools are required to build this project:

• make

• Docker

• Glide for dependency management

If you intend to re-generate mocks for testing, install:

• Mockery

If you would like to run tests using the ginkgo command, install:

• Ginkgo

Get the source

cd $(go env GOPATH)   #defaults to ~/go
git clone -o upstream https://github.com/projectriff/function-controller src/github.com/projectriff/function-controller

Building

• To build locally (this will produce a binary named function-controller on your machine):

  make build

• To build for docker (and deploy as part of the whole riff installation):

  make dockerize

  This assumes that your docker client is correctly configured to target the daemon where you want the image built.

• To run tests:

  make test

• To attach a delve capable debugger (such as Goland) to a function-controller running inside k8s:

  make debug-dockerize

  Then expose the 2345 port as a service, using riff/config/delve/function-controller-debug.yaml:

  kubectl apply -f riff/config/delve/function-controller-debug.yaml

  Then you can connect the debugger through port 30102.
