I am running the latest docker for mac build and have a number of docker-compose based apps up and running - all accepting being called from my local network.
I am now trying to implement a node.js app that needs network access to scan the host's network as well as responding to port 5005.
Can anyone show me a docker-compose.yml file that would allow for the following networking:
Local network: 192.168.123/24 router 192.168.123.1
Docker for Mac is running on my macbook at 192.168.123.118
Inside my network http://192.168.123.118:5005 should respond to the node requests to the container.
The container needs to scan the local network to look for services.
I have tried combinations of default, bridge and host networks with one or two interfaces and have only gotten confused.
Can a container truly be part of the host network?
I seem to remember that this was achievable when running docker on virtualbox.
The actual code I'm trying to configure is https://github.com/jishi/node-sonos-http-api I don't think there are issues with the code, just the environment I am trying to create.
The project I am trying to run is the Sonos controller app:
Here are my Dockerfile and docker-compose.yml files and the command to build the Sonos controller app
mkdir sonos
cd sonos
git clone https://github.com/jishi/node-sonos-http-api sonos
docker-compse.yml
version: '2'
services:
sonos:
build: sonos
network_mode: host
sonos/Dockerfile
FROM node:4-onbuild
EXPOSE 5005
After this I can start the controller:
docker-compose stop; docker-compose-build; docker-compose up;
And the output is:

I feel that the sonos container running in host mode is not able to see my local network in order to discover my Sonos speakers.
