Node Red Docker Template

This is a lean template for node red applications to be run and hosted in docker.

Details

This repo contains a dockerfile, flow.json and settings.js file.

Dockerfile

The dockerfile is setup so that it uses the latest version of node-red it also exposes the default port for node-red 1880 additionally includes the flow.json and settings.js files.

Adding node modules

To add custom modules to the docker image you can uncomment the lines in the dockerfile for the node_modules and package.json.

Flow.json file

The example file just has a simple flow that outputs a timestamp in the debug window.

Settings.js file

The following settings are turned on which means the admin interface will be disabled when running it.

httpAdminRoot: 'false',

disableEditor: true,

If you like to have them enabled just comment the lines above.

Debugging and development

The simplest way to develop node-red with this docker template is not to build the docker image everytime you want to test or build your flows.

The easiest way to develop using this template is just to run a node red container and adding the correct volumes to it.

See an easy example below:

docker run -it --rm --name node-red -p 1880:1880 \
-v /path/to/settings/file:/data/settings.js \
-v /path/to/node_modules/folder:/data/node_modules \
-v /path/to/package/json/file:/data/package.json \
nodered/node-red

Please note that the flow.json file is not needed since you will want to edit and create new flows so you can use the import and export menu items of the admin interface for that.
