Welcome to the Node-RED Docker wiki

This wiki describes how Node-RED can be run in a Docker environment. It is assumed that some basic familiarity with Docker and the Docker Command Line are known. A good starting point can be found here.

Quick Start

Deploying a Node-RED Docker container is as simple as:

$ docker run -it -p 1880:1880 --name mynodered nodered/node-red

Let's dissect that command:

docker run	run a container.
-it	attach a terminal session so we can see what is going on
-p 1880:1880	connect internal local port 1880 to the exposed external port 1880
--name mynodered	a friendly name for the container.
nodered/node-red	the image to base the container on - currently Node-RED v1.0

Running the above command should give a terminal window with a running instance of Node-RED.

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.
