To override the entry point for any of the docker images. In the vertx image you can first avoid executing vertx and bash in to the container and then execute later

docker run -it --entrypoint=/bin/bash vertx/vertx3-exec

--rm removes the image as soon as you exit the container. Clean!!!
docker run -it --rm --entrypoint=/bin/bash vertx/vertx3-exec

View running processes

$ sudo docker ps
