enable distributed tracing using Spring Cloud Sleuth and Zipkin. This can be done with the following steps:

Add dependencies to the build files to bring in Spring Cloud Sleuth and the capability of sending trace information to Zipkin

Add dependencies on RabbitMQ and Kafka for the projects that haven't used them before, that is, the Spring Cloud projects authorization-server, eureka-server, and gateway

Configure the microservices to send trace information to Zipkin using either RabbitMQ or Kafka

Add a Zipkin server to the Docker Compose files

Add the kafka Spring profile in docker-compose-kafka.yml to the Spring Cloud projects authorization-server, eureka-server, and gateway
