Creating and running a MongoDB Docker container

docker run --name my-mongodb -v ~/mongodb/db:/data/db -d -p 27017:27017 mongo

-v ~/mongodb/db:/data/db mounts the ~/mongodb/db directory on the host, meaning the local computer running the container, to the /data/db directory in the container. If you do not set up a volume this way, the stored data is deleted when the container is deleted. Once deleted, container data cannot be recovered.

% docker run --name my-mongodb -v ~/mongodb/db:/data/db -d -p 27017:27017 mongo
