The queue didn't declared when I use Dockerfile1, but Dockerfile2 works.What's the difference between Dockerfile1 and Dockerfile2?

yes , there is difference in Dockerfile1 and Dockerfile2 . you are exposing port 15672 before queue creation in dockerfile2 and exposing after queue command in dockerfile1. Actually Rabbitmqadmin use HTTP API to create queue , exchange etc. if you apply command
curl -u guest:guest -XGET http://localhost:15672/api/queues
you will get list of all queues if you apply command :
curl -i -u guest:guest -H "content-type:application/json" \
-XPUT -d'{"type":"direct","durable":true}' \
http://localhost:15672/api/exchanges/%2f/my-new-exchange
it will create new exchange my-new-exchange. without exposing port how will you able to create queue ? . for more info you can go through manual of rabbitmq. http://hg.rabbitmq.com/rabbitmq-management/raw-file/3646dee55e02/priv/www-api/help.html
