If the node is not ready for people to use please don't publish it to npm it just confuses people.

If you want people to test the node they can do a npm from git with the following syntax:

npm install kpavel/node-red-node-openwhisk

Or at least remove the node-red from the keywords so it doesn't show up on flows.nodered.org

When I add a openwhisk action to run in local container, I get "local docker client not initilized" error. If I restart the node-red container, local container start and openwhisk action executes locally. What am I doing wrong?

In order to make local and Bluemix action invocations to work the same (in terms of interfaces), we need to wrap the payload in local client with {"value": args}.

start with nodejs

'namespace' is not initialized in local service

• Dynamically select proper images, using a naming convention (e.g., suffix: org/image-name-)

Introduce simple preemption controller, as follows:

• maintain idle times (and state) of each container
• periodic task (e.g., every 10 minutes - configurable) that would manage the amount of running containers
  • high watermark: if less than $HIGH running containers, do nothing
  • low watermark: stop containers with largest idle times, to achieve total number <= $LOW (<$HIGH)
• on action invocation, start container if not running
• config params in settings.js:
  openwhiskLocal: {
  preeemptionPeriod: 600, // in seconds
  preemptionHighThresholdPerHost: 20, // number of running containers
  preemptionLowThresholdPerHost: 10 // number of running containers
  }

var docker = new Docker({socketPath: '/var/run/docker.sock'});

Typical usage:

• Node-RED is running in a Docker container, on the same host as the docker engine used to host the action containers
• /var/run/docker.sock is mounted as VOLUME from the host
