./mvnw spring-boot:run -f todo-api -Dspring-boot.run.arguments="--spring.docker.compose.enabled=true --spring.docker.compose.file=$(pwd)/compose.yaml"
./mvnw spring-boot:run -f todo-frontend -Dspring-boot.run.arguments="--spring.docker.compose.enabled=true --spring.docker.compose.file=$(pwd)/compose.yaml"

Feel free to add new Todos or complete them.

You can see the tracing via Zipkin (http://localhost:9411)

Docker Compose will automatically start up when the app is started, but it will not automatically shut down, so if you do not need Zipkin after stopping the app, please shut down Docker Compose as well.
