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.
Deploying a Node-RED Docker container is as simple as:
$ docker run -it -p 1880:1880 --name mynodered nodered/node-redLet'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.
Welcome to 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.
