Docker¶

This guide will take you through the process of compiling and runnning an OpenDDS application with Docker. Docker images containing a pre-built OpenDDS are available in GitHub Container Registry. An image corresponding to a particular release has a tag of the form DDS-X.xx, e.g., DDS-3.23.

Prerequisites¶

Check that docker and docker-compose are installed.

docker --version
docker-compose --version

Compile the Messenger Example¶

Enter a container

docker run --rm -ti -v "$PWD:/opt/workspace" ghcr.io/opendds/opendds:latest-release

Copy the Messenger directory

cp -R /opt/OpenDDS/DevGuideExamples/DCPS/Messenger Messenger
cd Messenger

Configure and build the Messenger example

source /opt/OpenDDS/setenv.sh
mwc.pl -type gnuace
make

Exit the container
```
exit
```

Run the Messenger Example with RTPS¶

Enter the Messenger directory
```
cd Messenger
```
Run the Messenger example with RTPS
```
docker-compose up
```

Run the Messenger Example with InfoRepo¶

Enter the Messenger directory if not done as part of the previous section
```
cd Messenger
```

Run the Messenger example with InfoRepo

docker-compose -f docker-compose-inforepo.yml up

Use Control-C to kill the InfoRepo process
