How do I define the name of image built with docker-compose

I’m using docker-compose to create my development environment. I want to build a specific image, but I don’t know how to set a name for that image.

wildfly:
  build: /path/to/dir/Dockerfile
  container_name: wildfly_server
  ports:
   - 9990:9990
   - 80:8080
  environment:
   - MYSQL_HOST=mysql_server
   - MONGO_HOST=mongo_server
   - ELASTIC_HOST=elasticsearch_server
  volumes:
   - /Volumes/CaseSensitive/development/wildfly/deployments/:/opt/jboss/wildfly/standalone/deployments/
  links:
   - mysql:mysql_server
   - mongo:mongo_server
   - elasticsearch:elasticsearch_server

When I execute docker-compose everything is ok, but I get a random name for the new image. Is it possible to set a name to the build image?
