node-red-contrib-docker-stream

I thought Node-RED was a pretty cool guy. Docker is pretty darn nifty, too. This is the beginnings of what should hopefully be a nice collection of nodes to allow for interactions between the two.

Right now there is support for monitoring a docker daemon's event stream, but I'm currently mulling over how to provide a clean interface for functional interactions with docker. Please feel free to open an issue if you have something specific you'd like to do.

Installation

General node installation instructions can be found here for Node-RED. But it boils down to this:

cd $HOME/.node-red # Or whever your Node-RED user data directory is
npm install node-red-contrib-docker-stream

Usage

An example flow can be found in example/.

TODO

Some things that I know need work.

• Better daemon connection handling. Dockerode should handle this pretty well, but I'd like to test.
  • Perhaps in at a config node level? I'd like to put host configuration into a config node anyways.
• Node(s) to gather information from daemon.
  • Would be nice to do something like set a delay/trigger on container down, then check status to see if daemon fixed it.
  • Currently in progress. See dev branch.
• Send commands/actions to daemon.
  • Wait, someone added a new container! I wanna do the same on another daemon but don't have service/swarm set up.
  • Currently in progress. See dev branch.
• Add filters to event watcher
  • The event stream can be filtered with arguments easily, and would prevent the need to use a filter node or switch.
• Add ability to stream logs.
  • One input node type that maps to a single container, probably.
