3. Docker Image (recommended)

eProsima distributes a Docker image of Fast DDS Spy with Ubuntu 22.04 as base image. This image launches an instance of Fast DDS Spy that is configured using a YAML configuration file provided by the user and shared with the Docker container. The steps to run Fast DDS Spy in a Docker container are explained below.

1. Download the compressed Docker image in .tar format from the eProsima Downloads website. It is strongly recommended to download the image corresponding to the latest version of Fast DDS Spy.

   
   

2. Extract the image by executing the following command:

   load ubuntu-fastddsspy:<version>.tar
   

   where version is the downloaded version of Fast DDS Spy.

   
   

3. Build a Fast DDS Spy configuration YAML file on the local machine. This will be the Fast DDS Spy configuration file that runs inside the Docker container. Open your preferred text editor and copy a full configuration example into the /<fastddsspy>/FASTDDSSPY_CONFIGURATION.yaml file, where fastddsspy is the path where to execute the tool. To make this accessible from the Docker container we will create a shared volume containing just this file. This is explained in next point.

   
   

4. Run the Docker container executing the following command:

   docker run -it \
       --net=host \
       --ipc=host \
       --privileged \
       -v /<fastddsspy>/FASTDDSSPY_CONFIGURATION.yaml:/root/FASTDDSSPY_CONFIGURATION.yaml \
       ubuntu-fastddsspy:v0.3.0
   

   It is important to mention that both the path to the configuration file hosted in the local machine and the one created in the Docker container must be absolute paths in order to share just one single file as a shared volume.

   After executing the previous command you should be able to see the initialization traces from the Fast DDS Spy running in the Docker container. If you want to terminate the application gracefully, just press Ctrl+C to stop the execution of Fast DDS Spy.
