Fast DDS - Vulcanexus Topic Intercommunication Demo

This project contains code for demonstrating intercommunication between Vulcanexus and Fast DDS applications. It provides a Vulcanexus application which instantiates a publisher on a HelloWorld topic, and a Fast DDS subscriber application that subscribes to it. Furthermore, it provides a Dockerfile to ease the building and showcasing process.

Build the Docker image

To build the Docker image, run (from this directory):

docker build -f Dockerfile -t dds2vulcanexus .

Build the demo

This demo requires two shells, one for the Vulcanexus publisher and another one for the Fast DDS subscriber.

Run the Fast DDS subscriber

1. Open a shell and run:

    docker run -it --rm dds2vulcanexus
    

1. From within the container, run:

    fastdds_subscriber
    

The subscriber application will start showing messages as soon as the publisher is run. It can be killed with CTRL-C.

Run the Fast DDS subscriber

1. Open a shell and run:

    docker run -it --rm dds2vulcanexus
    

1. From within the container, run:

    vulcanexus_publisher
    

The publisher application will start sending messages that will be received by the Fast DDS subscriber in the other shell. The publisher can be killed with CTRL-C as well.
