predixedge/predix-edge-node-red repository overview

⁠edge-node-red

see https://nodered.org/docs/platforms/docker⁠

Predix Edge node-red projects require a config/settings.js Your existing flows.json may also be in /config and will get picked up when running in Predix Edge

The entry_point.sh script launches the app.

When using this container in multi-module project, each project can have different settings.js or flows.json simply by creating different Predix Edge config.zip files and deploying via Edge Manager or PETC. See the Predix Edge Reference App⁠ for details.

⁠Build new container using Dockerfile

Can include other nodes from npm this way.

docker build -t predixedge/predix-edge-node-red:<tag> .       //where tag is latest or a version

or when behind a proxy server

docker build --build-arg HTTP_PROXY --build-arg HTTPS_PROXY -t predixedge/predix-edge-node-red:<tag> .

⁠Run container locally

docker run is more like docker create in concept. It creates a container instance.

docker run -it -p 1880:1880 --name predix-edge-node-red predixedge/predix-edge-node-red

⁠Run container locally like Predix Edge

In order to be on the same network as another docker stack, use docker stack to deploy the containers.

docker stack deploy -c docker-compose-local.yml predix-edge-node-red

⁠Node-Red Node Development

For Development of Nodes: map this repo dir to /config of container. This is why our nodes live in a folder called node_modules. e.g. see example lower-case node. Because Node-Red looks for nodes in the /config/node_modules dir.

docker run -it -p 1880:1880 -v `pwd`:/data --name predix-edge-node-red predix-edge-node-red

cd node_modules/lower-case
npm install
docker stop predix-edge-node-red; docker start predix-edge-node-red
refresh node-red in browser
repeat

To detach:

ctrl-p ctrl-q

docker attach predix-edge-node-red

docker stop predix-edge-node-red; docker start predix-edge-node-red

docker start predix-edge-node-red

⁠Open a shell in the container

docker exec -it predix-edge-node-red /bin/bash

⁠Adding Node Red Nodes

#example of how to add more node-red nodes #RUN npm install node-red-node-wordpos
