thingsboard-udp-loadbalancer's Introduction

ThingsBoard UDP Load Balancer

The Load Balancer is designed to support popular CoAP and LwM2M use-cases, where the main priority is to maintain the route table between clients and servers.

Building from sources

Build scripts require Linux based OS and the following packages to be installed:

  • Ubuntu 16.04+
  • CentOS 7.1+
  • Java 11
  • Maven 3.1.0+

Build

After you've downloaded the code from GitHub, you can build it using Maven:

mvn clean install

Build artifacts

You can find debian, rpm and windows packages in the target folder:

application/target

Build local docker images and publish

  1. Change the repository name in the msa/pom.xml file.
  2. Execute the following command: mvn clean install -Ddockerfile.skip=false -Dpush-docker-image=true

thingsboard-udp-loadbalancer's Issues

.deb systemd service fails to initialize due to logger

When trying to run the load balancer through the systemd service, I am met with a handful of exceptions in my journalctl logs, and the app crashes.

$ sudo systemctl start tb-udp-lb

I'm willing to bet that it's caused by root owning the logs. Not 100% sure how that happened, could be my bad.

chowning the file back to thingsboard:thingsboard seems to resolve the issue.

Add build instructions?

I am very much not a Java person, but I'd like to try out this LB. I see that it uses Gradle, but I can't get it to build with a Debian container. I get errors about a specific plugin:

...

FAILURE: Build failed with an exception.

* Where:

But got another error:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.
