Start mongoshell from a makefile. I recommend it for simple tasks, like a exercise in class.

MongoShell-Makefile

shell:
	@docker start mongoserver
	@docker start mongoshell -i
	@docker stop mongoshell mongoserver

connect: createMongo
	docker run -it --name mongoshell --link mongoserver:mongo mongo sh -c 'exec mongo "$$MONGO_PORT_27017_TCP_ADDR:$$MONGO_PORT_27017_TCP_PORT"'
	@docker stop mongoshell mongoserver

createMongo:
	@docker run  --name mongoserver -p 27017:27017 -p 28017:28017 -d mongo

cleanMongo:
	@docker rm mongoshell mongoserver
