How to restore Docker data volumes

To restore a container using the backup of data volumes taken, first create a new container by providing data volume and container names:

docker run -p 27017:27017 --name mongodb e43a2492d00f

e43a2492d00f = image-id

docker run -p 27017:27017 --rm --volumes-from mongodb -v $(pwd):/backup e43a2492d00f  tar xvf /backup/mongodb.tar

docker restart mongodb

mongodb = name of stop container

To push container as a image on docker-hub
