Install.md

Install docker as per latest instructions at

https://docs.docker.com/installation/

e.g. for Ubuntu 14.04

sudo apt-get update
sudo apt-get install linux-image-generic-lts-trusty wget
wget -qO- https://get.docker.com/ | sh

add yourself to docker group for when you get fed up with all the sudo below...

sudo usermod -aG docker $USER
sudo service docker restart

install Node-RED from the gist above

sudo docker build -rm -t davecj/node-red http://gist.github.com/raw/9435867/Dockerfile
or
sudo docker build -rm -t davecj/node-red git://gist.github.com/9435867.git

(or copy / paste the Dockerfile and build)

sudo docker build -rm -t davecj/node-red - < Dockerfile

Note: there will be errors during the npm install - but they should be warnings about gyp failing to build icu and serialport - but they will fail back to pre-compiled versions ok. So all should be ok.

run (as daemon)

sudo docker run -d -p 1880:1880 --name mynodered davecj/node-red

start a command line inside the container

sudo docker run -it --rm -p 1880:1880 --name mynodered davecj/node-red /bin/bash

show running containers

sudo docker ps -a

show all images (so you can tidy up)

sudo docker images

How can we pass the creds/ environment variable?
