Easy-NMOS Docker Compose Solution

This starter kit allows the user to launch a simple NMOS setup with minimal installation steps. It is composed of three Docker containers:

• an NMOS Registry (from nmos-cpp)
• a virtual NMOS Node (from nmos-cpp) which should automatically register
• the AMWA NMOS Testing Tool

All you need is a Linux host (Windows and Mac hopefully coming soon), with a recent version of Docker and Docker Compose installed. Alternatively, you can run the implementation inside a Linux virtual machine on any platform.

Finally, if you want/need access to the build instructions for these containers you can use the following links:

• nmos-cpp container from NVIDIA
• AMWA NMOS Testing Tool container from AMWA

Brief installation instructions

0. Clone this repository locally or download and unpack the archive

1. Install Docker and Docker Compose

Follow the short instructions.

2. Configure Compose IP addresses for your environment

You will need 3 unused IP addresses that all reside in the same subnet as the host IP address. The docker-compose script by default starts all the containers with externally facing IP addresses so that they are easily accessible from your LAN.

Configure the following inside the "docker-compose.yml" file

• Set a valid IP address for the NMOS Registry/Controller to be exposed on. Replace 192.168.6.101 with something unused and appropriate in the "Create nmos-registry container instance" section
• Set a valid IP address for the NMOS Virtual Node to be exposed on. Replace 192.168.6.102 with something unused and appropriate in the "Create nmos-virtnode container instance" section
• Set a valid IP address for the AMWA NMOS Testing Tool to be exposed on. Replace 192.168.6.103 with something unused and appropriate in the "Create nmos-testing container instance" section
• Adjust the network interface to use your specific host interface. Replace the "parent: ens33" to match your external facing interface in the "external" section at the end of the file
• Adjust the external subnet to use. Replace the "subnet: 192.168.6.0/24" so that it correctly sets the subnet for the IP addresses you've defined above in the "external" section at the end of the file
• Note: In order for the Node to be correctly accessible the IP address specified must be different to the host IP address

3. Start Docker Compose to start Easy-NMOS

You should just be able to docker-compose up and then access the relevant host IP address and port.

In order to ensure you keep the docker images up-to-date, just docker-compose pull before the docker-compose up.

Quick Start Guide

Default Ports and mDNS hostnames

Services	mDNS name	Opened ports
NMOS Registry/Controller/MQTT Broker	nmos-registry.local	80 (HTTP), 81 (WebSocket), 1883 (MQTT)
NMOS Virtual Node	nmos-virtnode.local	80 (HTTP), 81 (WebSocket)
AMWA NMOS Testing Tool	nmos-testing.local	5000 (HTTP)

These values appear in "docker-compose.yml", "registry.json" and "node.json".

How to Browse to respective NMOS services and tools

Assuming your client device is correctly supporting mDNS and is on the same LAN as the host running the containers you should be able to use the mDNS hostnames. If this does not work please try the respective IP addresses etc.

Browse to the NMOS Controller

http://nmos-registry.local/admin

Browse to the AMWA NMOS Testing Tool

http://nmos-testing.local:5000/

Browse to the APIs of the NMOS Registry

http://nmos-registry.local/x-nmos

Browse to the APIs of the NMOS Node

http://nmos-virtnode.local/x-nmos

Next steps for this project

• Identify a Windows and Mac equivalent for macvlan driver in order to connect to LAN network
• Expand the README.md file to explain what can/can't be done with easy-nmos
• Expand the README.md to explain the use of the "registration.sh" script to disable the nmos-registry so that the testing tool can be used to test the nmos-virtnode - Current work-around is to use docker-compose stop nmos-registry
