I've been following the documentation ([Running under Docker : Node-RED](https://nodered.org/docs/getting-started/docker)) but can't figure it out. It builds but when I try to open 127.0.0.1:1880 I get ERR\_CONNECTION\_REFUSED in Chrome, so the web service is not running?

What I wanted to do is add support for Elasticsearch with the package from Jeff, this is my Dockerfile:

```auto
FROM nodered/node-red:latest
USER root
RUN npm install node-red-contrib-elasticsearch-jd
USER node-red

```

Build it:

`docker build -t test/noderedext:latest .`

Run it:

`docker run test/noderedext -p 1880:1880 -d`

I know I'm not mounting any volumes her, so I will get the warning up on the dashboard but for now I only want to add the dependency before I go ahead and complete the container.
