DMR Homebrew Server with IPSC Bridge

Dockerfile

This Dockerfile packages up some great code the other people wrote:

• dmrlink by N0MJS, IPSC_Bridge branch, https://github.com/n0mjs710/DMRlink/tree/IPSC_Bridge
• hblink by N0MJS, HB_Brige branch, https://github.com/n0mjs710/HBlink/tree/HB_Bridge
• ipscbuild by Vance w6ss@dx40.com

Docker is best at running a single application. In this case, we wanted to run 2 applications. Supervisord is employed to run HB_Bridge and IPSC_Bridge, Docker thinks we're just running Supervisor.

Config

Before you begin, you must edit the configuration files.

hblink.cfg

Defines parameters for homebrew. Master means: open a port and wait for HB clients to connect. Your hotspot (Pi-Star or openSpot, etc) will connect here. The default port is 55555/udp. Docker requires an additional layer of port mapping, so be sure to connect to your exposed port.

HB_Bridge.cfg

Defines AMBE ports for talking to IPSC_Bridge. Also, defines the talkgroup deck.

dmrlink.cfg

Defines parameters for IPSC master and peers. If you have a cBridge, use it as an IPSC master.

IPSC_Bridge.cfg

Settings paired (inverted) from HB_Bridge.cfg. HB_Bridge and IPSC_Bridge will use these 2 ports to communicate.

Other Config

supervisord.conf

Build

Clone a copy of the Dockerfile

git clone https://github.com/KI7SBI/HomebrewDocker.git

Edit your config files

cd HomebrewDocker
nano ...

Build the Dockerfile

When you run the following build command, config files are copied into the docker image. Name:Tag can be set to any value you wish. sudo docker build -t HBIPSCDocker:config1

Multiple copies or versions

Edit config files, and build again, using a different tag. For example, sudo docker build -t HBIPSCDocker:pnwdigital

#Run Remember to map exposed ports. sudo docker run -d -p 50001:55555 HBIPSCDocker:config1 sudo docker run -d -p 50002:55555 HBIPSCDocker:pnwdigital

Connect your hotspot

Hotspots in MMDVM Server mode may connect to your port 50001 to use config1 bridge settings. Or, connect to 50002 to use pnwdigital bridge settings.

Manage Docker Instances

docker ps
docker images
docker kill

#Why Docker? Yes, docker has a learning curve. It may seem unnecessary for you, and perhaps it is in your case. The goal in containerizing the HB+IPSC pair is primarily to simplify running multiple instances on a single server. If you dont care to run multiple instances, then you may always just install these apps directly.
