This Dockerfile defines an image for running MongoDB. It installs MongoDB from the official MongoDB repository, configures it to listen on all interfaces, exposes port 27017, and sets mongod as the default command to run a MongoDB instance when containers are created from this image. Building this image would result in a balboa/mongo image that can be run to start a MongoDB server in a container.
