Docker images are available on Docker Hub. Check the latest tag (version) available. Run the application with:

docker run -p 8086:8086 -d mpergolesi/exp-nsd-composer:<latest-tag>

Wait for the application to start, then test it with:

curl http://localhost:8086/vsb/schema

Development

Some dependencies are not available in Maven repository. Check pom.xml.

Compile the project with:

mvn clean package

Build the Docker image with:

docker build --no-cache=true --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') \
    --build-arg BUILD_VERSION=$(mvn help:evaluate -Dexpression=project.version -q -DforceStdout) \
    -t <your-repo>/exp-nsd-composer:$(mvn help:evaluate -Dexpression=project.version -q -DforceStdout) .

Graph export for visualization

Debug log often provides network topology export into graphviz format. Running tests will produce output examples.

Copy the output to a text file called 'example.txt' and create a PNG with

circo -Tpng example.txt -o example.png

Or copy the output to an online Graphviz editor like Edotor.
