Run it without mongodb.

docker run -it --rm mulspace/meteor bash

Run it with mongodb

Start the two containers

 docker run -itd --name mongo mongo
 docker run -it --rm --link mongo:mongo -p 3000:3000 mulspace/meteor bash

Then run the command in meteor container.

meteor create test && cd test && MONGO_URL=mongodb://mongo:27017/test meteor

Run the meteor directly when start the container.

docker run -it --rm --link mongo:mongo -p 3000:3000 \
    -v $PWD:test:/home/meteor \
    mulspace/meteor \
    bash -c "cd test && MONGO_URL=mongodb://mongo:27017/test meteor"
